What is the wall that separates the left side from the right side of the heart Why is it important?
The right and left sides of the heart are separated by a muscular wall that prevents blood without oxygen from mixing with blood that has oxygen.
Why are the walls of the left and right ventricle different?
Further, the left ventricle has thicker walls than the right because it needs to pump blood to most of the body while the right ventricle fills only the lungs.
What is the function of the septum separating the left and right ventricles?
When a person has a VSD, there’s an opening in the septum between the left ventricle and right ventricle. This part of the septum is called the ventricular septum. This hole allows blood from the left ventricle to go back into the right ventricle instead of out of the heart through the aorta.
What is the heart wall?
The heart wall consists of three layers: the endocardium, myocardium and epicardium. The endocardium is the thin membrane that lines the interior of the heart. The myocardium is the middle layer of the heart. It is the heart muscle and is the thickest layer of the heart.
What separates the left atrium from the left ventricle?
The atria are separated from the ventricles by the atrioventricular valves: The tricuspid valve separates the right atrium from the right ventricle. The mitral valve separates the left atrium from the left ventricle.
What is the name of the valve that separates the left ventricle from the aorta?
Aortic Valve
Aortic Valve Separates the left ventricle from the aorta. Opens to allow blood to leave the heart from the left ventricle through the aorta and the body.
Why is the wall of the right ventricle thicker than the wall of the right atrium?
This means blood travels through the heart twice in one circulation of the body. Ventricular walls are thicker than atrial walls because the ventricles have to pump blood further.
Why is the wall of the right ventricle thinner?
Wall of right ventricle is thinner than the left one, since it has to push blood only up to the lungs through the pulmonary aorta. But the left ventricle has to push blood to all parts of the body including the extremities. Hence its wall has to be quite thick.
