The closure of which valves causes the sound lub and dup

Answers

Answer 1

Answer:

The sound "lub" is produced by the closure of the atrioventricular valves (mitral and tricuspid valves) while the sound "dub" is produced by the closure of the semilunar valves (aortic and pulmonic valves).

Explanation:

The question above is related to the body's circulatory system. The heart is pumping non-stop in order to deliver oxygenated blood to the body. Blood follows a particular flow once it enters and leaves the heart. Part of that flow produces the "lub" and "dub" sound. These sounds are produced by the two valves that ensure the blood follows a correct path. These are the atrioventricular valves and the semilunar valves.

The atrioventricular valves are located in the middle of the atria and the ventricles while the semilunar valves are located at the bottom of the vessels. Once the blood flows towards the atrioventricular valves and they close, it produces the "lub" sound, also called the first heart sound. When the blood flows towards the semilunar valves and they close, it produces the "dub" sound, also called the second heart sound.

How do extreme temperatures affect my body system?
How does infection affect my body system?
How can cancer affect my body system?

Answers

Answer:

I am the immune system. I help fight off viruses and bacteria from living things. Also known as microbes! The main parts of my immune system are white blood cells, antibodies, the spleen, the thymus, the bone marrow, The complement system, and The lymphatic system. When I try to explain what an immune system is, I think of swiss cheese! Yum. There are about three levels to an my system. There's innate, which everyone is born with. There's adaptive, which you can develop throughout life, and passive, which is a borrowed source. So anyway, there are multiple layers of the my immune system. Like layers of cheese. And like swiss cheese, there are holes in random places. And those holes don't always line up, which makes it harder for viruses and bacteria to get through. But when a body doesn't get enough rest, or nutrients, it makes it harder to fight those microbes off! So then there are like, bigger holes, like they line up more, and so it's not as hard for microbes to get in.

Infection affects the body system because there are viruses, bacteria, microbes in your body. Especially if you don't get enough rest or whatever your body needs, it makes it all the harder for your immune system to fight it off. Because of the microbes, your body is now infected with bacteria and things that can hurt you. This can cause stuff such as constipation, vomiting, runny nose, headache/migrane, diarreah, dehydration, fatigue etc. Which is why, we have doctors and trained specialists for medicine and cures to help our immune system, give it a little boost.

The excretory system removes the waste and excess fluids from the body. Extreme temperatures, infections, and cancer have various impacts on the excretory system, which can affect its ability to function properly.

What is excretory system?

The excretory system removes waste products and excess fluids from the body. The kidneys filter the blood and produce urine. The excretory system also maintains electrolyte balance and regulate blood pressure.

The high temperatures causes dehydration, which lead to decreased urine output and kidney damage. The low temperatures causes decreased blood flow to the kidneys, which also causes kidney damage.

The excretory system can be affected by urinary tract infections which are caused by bacteria entering the urethra and multiplying in the bladder. Symptoms include painful urination, lower abdominal pain, etc.

The cancer can also affect the excretory system, specifically the kidneys and bladder. Symptoms of kidney and bladder cancer include blood in the urine, abdominal or back pain, and frequent urination.

Therefore, the excretory system removes the waste and excess fluids from the body and extreme temperatures, infections, and cancer have negative impacts on the excretory system.

3. Discuss ways parents can reduce the stress of parenting in these first two years, so they can model happy feelings for their babies and have energy for relationships with their infants.

Answers

1. The arrival of a new baby can be a joyful experience, but it can also be overwhelming and stressful for new parents. Here are some sources of support that can help new parents through the early days:

- Family and friends: Having a supportive network of family and friends can be a great source of comfort and help for new parents. They can provide emotional support, practical help with chores or errands, and even offer to babysit so parents can take a break.

- Healthcare professionals: Doctors, nurses, and midwives can offer advice and support on a range of issues related to the baby's health and well-being, as well as the mother's health postpartum. They can also refer parents to other resources if needed.

- Parenting classes: Attending parenting classes can help new parents feel more prepared and confident in their new role. Classes may cover topics such as feeding, sleeping, and caring for a newborn, as well as self-care for parents.

- Support groups: Joining a parent support group can provide a sense of community and connection with other new parents who are going through similar experiences. This can be especially helpful for parents who may feel isolated or overwhelmed.

2. Parent Advice List for Reducing Toddler Tantrums:

- Maintain a consistent routine: Toddlers thrive on routine, so sticking to a consistent daily schedule can help reduce their stress levels and prevent tantrums.

- Be clear and consistent with rules: Setting clear boundaries and rules for behavior can help toddlers understand what is expected of them and reduce frustration that could lead to tantrums.

- Provide choices: Giving toddlers a choice between two acceptable options can help them feel more in control and reduce the likelihood of tantrums.

- Acknowledge and validate feelings: Toddlers may have strong emotions that they don't yet know how to express. Acknowledging their feelings and offering comfort can help prevent tantrums.

- Distract and redirect: If a toddler is starting to get upset, distracting them with a new activity or redirecting their attention to something else can help prevent a tantrum.

- Stay calm and patient: It's important for parents to stay calm and patient when dealing with a toddler's tantrum. Reacting with anger or frustration can escalate the situation.

- Use positive reinforcement: Praising good behavior and offering rewards can help encourage positive behavior and reduce the likelihood of tantrums.

3. Ways Parents Can Reduce the Stress of Parenting in the First Two Years:

- Practice self-care: Taking care of oneself is essential to being a good parent. Parents should make time for activities that they enjoy and that help them feel relaxed and rejuvenated.

- Seek support: It's important for parents to ask for help when needed, whether that means asking a partner, family member, or friend for assistance or seeking professional support.

- Practice mindfulness: Mindfulness techniques, such as meditation and deep breathing, can help parents reduce stress and feel more present in the moment.

- Prioritize sleep: Getting enough sleep is essential for parents to have the energy and patience to care for their baby. Parents should make sleep a priority and try to establish a bedtime routine for themselves.

- Connect with others: Connecting with other parents who are going through similar experiences can provide a sense of community and support. Joining a parent group or attending playdates can be a great way to connect with others.

- Be realistic: It's important for parents to be realistic about what they can and cannot do. Setting realistic expectations can help reduce stress and prevent burnout.

Who invented the swimming technique now known as the freestyle? OA. South Pacific Islanders OB. Norwegians O C. Japanese OD. Australians PREVIOUS​

Answers

It was Australian swimmers who popularized the freestyle technique in competitive swimming, and it has remained a staple of the sport ever since. So, the correct option is D.

The swimming technique known as freestyle was not invented by any specific individual or group of individuals. Rather, it developed over time through various influences and adaptations.
Historically, swimming has been a part of human culture and activity for thousands of years, with depictions of people swimming found in ancient Egyptian and Greek art. Different cultures around the world developed their own unique styles of swimming, such as the sidestroke in England and the breaststroke in Japan.
However, as competitive swimming became more popular in the late 19th and early 20th centuries, swimmers began to experiment with different techniques to increase their speed and efficiency in the water.

One of these techniques, which eventually became known as freestyle, involved swimming on the front with the arms reaching forward alternately and the legs kicking in a fluttering motion.
While it is difficult to pinpoint a specific group or individual who first used this technique, it is believed to have developed through a combination of influences from various cultures and swimmers around the world.

Some credit South Pacific Islanders with creating a similar style of swimming, while others point to Norwegian swimmers who developed a similar technique for swimming in cold water. So, the correct option is D.

draw and label the blood floow in the human body​

Answers

The description provides a general overview of blood flow in the human body, and there are numerous branches and connections throughout the circulatory system to ensure proper oxygenation and nutrient delivery to all cells and organs.

The human body consists of a complex network of blood vessels that make up the circulatory system.

These blood vessels include arteries, veins, and capillaries, and they are responsible for the transportation of oxygen, nutrients, hormones, and waste products throughout the body.

The journey of blood begins in the heart, which acts as a pump.

The heart contracts and pumps oxygen-rich blood into the aorta, the largest artery in the body.

The aorta branches off into smaller arteries that carry the oxygenated blood to various organs and tissues.

As the arteries travel away from the heart, they progressively divide into smaller vessels called arterioles.

Arterioles then give rise to even smaller vessels called capillaries. Capillaries are the tiniest blood vessels, and their thin walls allow for the exchange of oxygen, nutrients, and waste products with the surrounding cells.

From the capillaries, blood flows into venules, which gradually merge to form veins.

Veins carry the deoxygenated blood back towards the heart.

The largest vein in the body, the superior vena cava, returns blood from the upper body, while the inferior vena cava returns blood from the lower body.

Finally, the deoxygenated blood enters the right atrium of the heart, and the cycle begins again as the heart pumps the blood into the lungs to pick up oxygen and release carbon dioxide.

Suppose you were seeking a child-care setting for your baby. What would you want it to be like and why?

Answers

Answer:

I would seek a private home where your baby gets one on one care or a nanny who came into my home. Having been in charge of programming for Day Care centers I know how fast they turn over employees and I also know, that despite the cameras, that babies get ignored and can, sadly, be abused.

Child-care workers are not there to love your baby. That is not what they get paid to do.

A baby needs a lot of love. You can’t just give them love after work; they need it all day long.

Child care center workers are there to give children basic care in a kind way.

You might want your baby to get a lot of one on one time however, that will not happen as the ratio of babies to care-givers is higher than that.

So, do not expect your baby to get picked up right away when it cries, changed as often as you would like, or to be fed immediately when he/she is hungry. Care-givers can only feed one baby at a time. Change one baby at a time and hold one baby at a time. Your baby will learn to wait and that can make infants feel insecure as having their needs met as soon as possible teaches them to trust that their needs will be met. When that happens a baby grows secure and is less fussy.

I had to leave the industry as I could not take seeing all these young babies crying as they waited for their turn. A three-year-old can wait; a two-month-old should not have to.

Some people brag that their babies do not cry very much after being in a child-care center thining which means they have a “good baby”. But, that is not what it means. It means that the baby has learned that crying to get held, to be changed, to be played with, or to get their diaper changed did not work so they simply stop crying as much.

You see this happen with babies in foster care as well.

Do not think that just because a daycare center has cameras that your baby is not being called rude names you cannot hear or is being pinched where you can not see it. I am not trying to scare you I am telling you what goes on that they will not admit to. Part of the reason turnover of child care center employees is so high is that even though they screen potential workers some who are not good care-givers do get hired.

A study done has shown that parents, who were in child-care centers themselves as children, are now choosing to not put their children in such care. They are choosing for the mother (or the father) to be a stay-at-home parent that cares for their own baby. I find that interesting.

If you can stay home with your baby as long as you can. That way you imprint on your baby; not rotating strangers.

If you can’t do that then work opposite your husband’s schedule so one of you is almost always home with the baby. Perhaps a family member can watch the baby when both of you are not available.

Or, work part-time and spend as little time away from your baby as you can.

Babies are not little adults. They are babies. Babies learn from those who care for them the most.

If that is not you, then your baby is going to learn from others and you cannot stop that from happening.

If you choose a child-care center you have to hope their turnover rate is not high. They will tell you it is not but that is because they do not want any negatives to be known.

I can’t tell you what I would look for in a center as I would not be looking for one. The ones I worked for were expensive and still, there were problems.

My own daughters stayed home with their babies after seeing childcare centers from the inside out. One is a Realtor now; a job that allows her to make her own schedule and put her baby with family when she does need to work outside the home.

One thing I tell parents is to make up a worksheet where they list all the expenses that come with the mother working and the baby being in daycare.

Those expenses are everything from gas in her car, maintenance of her car, clothes, lunch-time meals, fast food meals for dinner, day-care costs, etc.

I tell them to take that number and subtract it from what the mother brings home, after taxes and any other deductions.

They take a look at that number so they can decide if the mother working, outside the home, makes sense financially.

I have seen women working and putting their baby in daycare while only bringing fifty dollars or less of added income to the family after expenses connected to her working are deducted.

I then advise those women to find something to do, from home, that pays.

I have seen some very creative women who work from home, with their baby and end up making more than they did at their office jobs.
