The superior and inferior vena cava are classified as large blood vessels called veins. In the circulatory system, veins are responsible for carrying deoxygenated blood from various parts of the body back to the heart. The superior vena cava and inferior vena cava are the two primary veins that perform this crucial task.
The superior vena cava, located in the upper part of the body, collects deoxygenated blood from the head, neck, upper limbs, and chest region. It then transports this blood to the right atrium of the heart. On the other hand, the inferior vena cava is responsible for carrying deoxygenated blood from the lower part of the body, including the abdomen, pelvis, and lower limbs, to the right atrium.
Both the superior and inferior vena cava play a vital role in maintaining the circulatory system's function, as they help to complete the blood circulation loop. By transporting deoxygenated blood back to the heart, these large veins ensure that the blood can be oxygenated once again in the lungs before being pumped to the rest of the body by the heart.

Bones that join together and are held in place with threads of collagen form a(n):_________
Bones connected by threads of collagen form a fibrous joint. These joints might include sutures, gomphoses, and syndesmoses, which are found in the skull, between teeth and jaw, and between parallel bones respectively. These joints serve to protect internal organs, provide body strength, and ensure weight-bearing stability.
Explanation:Bones that join together and are held in place with threads of collagen form a fibrous joint. These joints are where adjacent bones are united strongly by fibrous connective tissue. The connective tissue that fills the gap between the bones may be narrow or wide. There are three types of fibrous joints: sutures, gomphoses, and syndesmoses. A suture is a narrow fibrous joint that unites most bones of the skull. At a gomphosis, the root of a tooth is anchored across a narrow gap by periodontal ligaments to the walls of its socket in the bony jaw. A syndesmosis is a type of fibrous joint that unites parallel bones and is found between the bones of the forearm (radius and ulna) and the leg (tibia and fibula). The gap between these bones may be wide and filled with a fibrous interosseous membrane, or it may be narrow with ligaments spanning between the bones. Fibrous joints provide protection to internal organs, add strength to body regions, and offer weight-bearing stability.

Normally, pancreatic enzymes assist the intestines in breaking down food. In a child with cystic fibrosis, the pancreatic duct is blocked by mucus, making it impossible for these natural enzymes to reach the gut.
Undigested lipids and proteins result in fatty stools in the absence of pancreatic enzymes. Normal stools should result from pancreatic enzyme therapy; fatty stools are produced when therapy is not adhered to. Bloody stools, pee with glucose, or bloody urine are not signs of noncompliance. Steatorrhea indicates that your stools contain too much fat (poop). It is a sign of malabsorption of fat. This indicates that your digestive system is having difficulty metabolising and absorbing lipids. Your organs could be impacted by this issue, one or more.
