Answer:
The muscular wall of the left ventricle is thicker than that of the right ventricle because the left ventricle requires higher forces to carry out its function- pumping blood through the systemic circuit.
Explanation:
The ventricles are located at the bottom of the heart. Their main function is to collect and pump blood to the rest of the body.
The right ventricle pumps deoxygenated blood into the lungs via the pulmonary artery. It requires a low pressure to carry this function out.
The left ventricle pumps oxygenated blood to all the tissues in the body. As a result, it requires higher forces than the right ventricle. Therefore, the muscle wall of the left ventricle is thicker than that of the right ventricle (it is the thickest of all the heart chambers).
These stem cells come from embryos that are three to five days old. At this stage, an embryo is called a blastocyst and has about 150 cells. These are pluripotent (ploo-RIP-uh-tunt) stem cells, meaning they can divide into more stem cells or can become any type of cell in the body.
