Question

The wall of the left ventricle is thicker than the right ventricle, explain.

Answer 1

Hint: The bird and mammalian heart are made up of four chambers – two auricles and two ventricles. The ventricles help to pump blood that reaches to the different body organs.

Complete answer: The left atrium is attached with a pulmonary vein that carries oxygenated blood from the lungs to the heat.
1. The left atrium and left ventricle are attached with a mitral valve that passes the oxygenated blood to the left ventricle.
2. The left ventricle then pumps the oxygenated blood to all the body organs by the aorta.
3. On the other hand, the right atrium is attached with superior and inferior vena cava that carries deoxygenated blood from the whole body to the heat.
4. The right atrium and right ventricle are attached with a tricuspid valve that passes the deoxygenated blood to the right ventricle.
5. The right ventricle then pumps the deoxygenated blood to the lung by the pulmonary artery.
6. The wall of the left ventricle is thicker than that of the right one because the left ventricle pumps blood against the gravity so that the oxygenated blood can reach the brain by the carotid artery. If the wall of the left ventricle is not thick then blood will not reach the brain and as a result, the brain will not get oxygen for their work.

Note: The arteries carry oxygenated blood in the body, but the pulmonary artery is the only artery that has an exceptional character of carrying deoxygenated blood. Similarly, the veins carry deoxygenated blood in the body, but the pulmonary vein is the only vein that has an exceptional character of carrying oxygenated blood in the body.
