Question

Oxygenated blood is carried by
A) Pulmonary artery
B) Pulmonary vein
C) Renal vein
D) Hepatic portal vein

Answer 1

Hint: To avoid the backflow of blood, valves are present. The right side pumps the lungs with deoxygenated blood. The left hand supplies the body's organs with oxygenated blood.

Complete Answer:
The primary organ associated with blood pumping is the heart. The arteries transport oxygenated blood to the body from the heart, while the veins transport deoxygenated blood to the heart for purification from various areas of the body.

Now, let us find the solution from the options-
-Deoxygenated blood is transported away from the heart by the pulmonary artery, while the pulmonary vein takes oxygenated blood to the heart.
- The oxygenated blood is transported from the lungs to the left atrium by the pulmonary veins. This process is known as auricular circulation.
- Oxygenated blood from the lungs is transported to the left atrium by the pulmonary vein. In the human body, it is the only vein which carries oxygenated blood.

Thus, the correct answer is option (B) Pulmonary vein.

Note: As it pumps blood throughout the body, the left ventricle wall is thicker than right, whereas the right pumps blood to the lungs above the heart. Ventricular walls are wider than arterial walls because blood needs to be more circulated by the ventricles.
