Purpose
The purpose of the lab is to dissect a pig heart in order to identify all of the parts of main chambers, valves, and vessels. To able to know the circulation the blood through the heart to the lungs and identify each section of the pig heart. The pig heart has four chambers which it is two atria and two ventricles. They both pump the blood and give the body what it needs. The heart has four valves which help the blood flow. There are 5 main types of blood vessels that enter and leave the heart.
Hypothesis
If the heart is pumping the blood through the body, then it is connect to the vascular system. The vascular is also called cardiovascular systems that contains blood vessels and lymph through the body. It helps circulate the blood

The data have supported the hypothesis because it showed that vessels is connect to the heart. The right atrium and left atrium are part of the chambers in the heart. Right atrium received deoxygenated blood and pumps it into right ventricle that send to the lung so it can oxygenated. But, left atrium pumping oxygenated blood to the tissues of the body. Right and left ventricles are part of the chambers. Right ventricle pumping the deoxygenated blood through the pulmonary valve and artery to the lungs. But left ventricle pumping oxygenated blood through the aorta and valve into the circulation. The aorta is main artery of the body and it is top of heart which carries the blood away from the body. The coronary artery supply oxygen-rich blood to the heart muscles. Pulmonary veins are large vessels that carrying oxygenated blood from the lungs to the left atrium which it is draining. Pulmonary trunk is a vessel that appear from the right ventricle and proceed deoxygenated blood from the heart to the lungs. Pulmonary arteries is from right ventricles of the heart to carry blood to the lungs for oxygenation. Semilunar valve of pulmonary artery located between the right ventricle and the pulmonary artery do it can pump the blood into the arteries, but will prevent blood that go opposite. Semilunar valve of aorta located between the left ventricle and the aorta. Bicuspid (mitral) valve loved between the left atrium and left ventricle which only let blood flow this way. Tricuspid valve located the right atrium and right ventricle which let the blood flow into ventricles. Chordae tendineae looked like strings in the heart. Intrerventricular septum is the wall that separating the lower chambers. The data show the location of each part of the heart that help pump the blood to benefit the body and remove the
