Current Question (ID: 14478)

Question:

The passage of blood from left atrium to body is

Options:

1. left atrium – left ventricle – Aorta – Body
2. left atrium – right ventricle – Aorta – Body
3. left atrium – left ventricle – Pulmonary Artery – Body
4. left atrium – left ventricle – Pulmonary Veins – Body

Solution:

The left atrium receives oxygenated blood from the lungs via the pulmonary veins. This blood then flows through the mitral valve into the left ventricle. The left ventricle pumps the oxygenated blood through the aortic valve into the aorta, which is the largest artery in the body. From the aorta, the oxygenated blood flows to the rest of the body's tissues and organs.
