What is the ratio of length of the small ntestine to the length of the large intestine? How does this compare with the ratio of the lengths of the intestines in humans?
The ratio of the length of the small intestine to the large intestine in pigs is 1:5, which is the same as humans. A pig's small intestine would usually measure from about 6 to 8 feet while its large intestine would measure from 1 to 3 feet. The length of a human's small intestine is normally about 7 metres withthe large intestine being about 1.5 metres long. The small intestine is longer than the large intestine, in both pigs and humans, despite it's little name.
What did you notice about the structure of the trachea? What is the function of the speacial design of the trachea?
The trachea has a unique design, similar to that of a bendy straw. It is a tube of smooth soft tissue, sturdied by c-shaped bands of cartilage, which keep the trachea from collapsing. This semi- rigid structure of the trachea allows it to remain flexible, yet prevents its from closing. If it were completely rigid, it would still allow air flow, but the neck would have no mobility. The combination of soft tissue, with cartilage, creates a perfect balance and is what makes the trachea the most appropriate for performing its function.
Which chamber of the heart was most muscular? Explain why?
The left ventricle was the most muscular in comparison to the other chambers of the heart because it exerts the most pressure. The atria only have to pump into the ventricles, and, while the right ventricle is quite muscular as well, it has to pump blood just to the lungs. The left ventricle,on the other hand, has to pump the oxygenated blood through the aorta, and the arteries, to the entire body. It has to pump blood over much longer distances and through many more capillary networks, making it the most muscular chamber of the heart.
How could you tell the arteries from the veins in the circulatory system?
Ateries are much thicker and are more elastic than veins because they are under much more pressure. Arteries are also found deeper inside the body, while veins have thinner walls and are closer to the surface of the skin.
