Heart dissection questions:
1) The muscles are much thicker in the left ventricle than the right ventricle because the left ventricle needs to pump blood and so needs a thicker muscle. The right ventricle receives the blood.
2) The aorta was very stretchy but tough; it was quite hard to cut through. Also it has a light shade of pink and it looks like a thick hollow tube-like artery. When you reach in the aorta, you can reach to different chambers of the heart, and you can feel the firm veins connecting through the heart.
3) The main artery of the body is the aorta, and so the aorta has its own blood supply to pump blood to all parts of the body.
4) There are 2 pulmonary veins,
5) The heart muscle is made up of Myocardium, the muscular tissue of the heart. The endocardium is in the inner lining of the heart, and the epicardium is the outer layer of the heart tissue.
6) The Mosaic heart valves from pigs are proved to be useful to replaces the human heart valves. The patients need to take stimulator drugs such as cyclosporine, Imuran, and prednosolone
