Internal Anatmoy Observations
Both the right as well left ventricles had thick walls however, the left ventricle had thicker walls than the right ventricle because it has to pump blood to the whole body while the right ventricle has to pump blood to the lungs so the blood becomes oxygenated. However, the right ventricle is bigger than the left ventricle and the color for both the ventricles were red also, the the left as well right atrium were red. The chordae tendinae look like strings that are attached to the heart walls near the tricuspid as well the mitral valve. The tricuspid, aortic, and pulmonary valve have 3 leaflets while the mitral valve only has 2 leaflets.
Internal Anatmoy Questions
- The most surprising thing about dissecting the heart was that how much more thicker the left atrium was compared to the right atrium because until the point of dissecting the heart, I thought that there was no difference then I realized that left atrium should be bigger than the right atrium because there is more pressure created in the left than the right.
- Atria and ventricles are different for countless reasons such as the ventricles are much larger, have thicker walls, and rougher to touch than the atria. Also, the left as well right atrium pump blood to the ventricles while the left ventricle pumps oxygenated blood to the entire body and the right ventricle pumps deoxygenated blood to the lungs.
- The left ventricle is more muscular than the right ventricle because it has to pump oxygenated blood to the entire body while the right ventricle has to pump deoxygenated blood to the lungs.
- There are four heart valves in the human heart which are known as the tricuspid valve, pulmonary valve, mitral valve and aortic valve. These four valves may be in different locations of the heart however, their functions are similar. The tricuspid valve closes to keep the deoxygenated blood coming back from the body in the right atrium then, opens to send it to the right ventricle. The pulmonary valve closes to keep the deoxygenated blood in the right ventricle afterwards, it opens to send deoxygenated blood through the pulmonary artery and to the lungs. The mitral valve closes to keep the oxygenated blood in the left atrium which is coming from the lungs and opens to send oxygenated blood to the left ventricle. Finally the aortic valve opens to send oxygenated blood through the aorta to the entire body however, it closes to keep the oxygenated blood in the left ventricle
