The following is a list of vessels. Place them in the order that blood would go through entering the systemic circulation. 1. Le
Alexus [3.1K]

Answer:

E. 3, 6, 7, 4, 5, 8, 1, 2

Explanation:

Systemic circulation is the circulatory pathway which is involved in the transport of the oxygenated blood to the body when pumped by the heart through arteries, capillaries and then back to the heart.

In the given question, the order of vessels in the systemic circulation has been asked which begins with the entry of the deoxygenated blood to the heart.

1. The deoxygenated blood enters the blood from vena cava to the right ventricle.

2. From the right ventricle, the blood enters the right atrium which pumps the de-oxygenated blood to the lungs through an artery called the pulmonary artery.

3. In the lungs, the blood becomes oxygen rich and is returned to the left atrium through the pulmonary vein.

4. The blood then enters the left atrium which is then pumped to the body through the main artery called the aorta.

This completes the systemic circulation and thus, Option-E is correct.
