Hint: Hint: The pulmonary artery carries blood from the heart to the lungs and the pulmonary vein carries blood from the lungs to the heart. The pulmonary artery carries deoxygenated blood, unlike the rest of the arteries. The pulmonary vein carries oxygenated blood, unlike the rest of the veins.
Complete answer:
The pulmonary artery has thicker walls in comparison to the pulmonary vein along with valves. Difference between the pulmonary artery and pulmonary vein-
So, the correct answer is ‘Both B and C’.
Note:
The pulmonary artery arises from the right ventricle of the heart. As it leaves the heart, the pulmonary trunk forks in two directions –the left and right pulmonary artery. The left and right pulmonary artery branches carry the deoxygenated blood to the left and right lungs respectively. There, the blood is combined with oxygen and pumped back into the heart through the pulmonary veins. This oxygenated blood rushes into the left atrium of the heart and is pumped to the left ventricle, and then eventually distributed through the aorta into the arteries which supply the oxygen-rich blood throughout the entire body.
Complete answer:
The pulmonary artery has thicker walls in comparison to the pulmonary vein along with valves. Difference between the pulmonary artery and pulmonary vein-
Pulmonary artery | Pulmonary vein |
The pulmonary artery carries Carbon-dioxide rich blood to the lungs. | The pulmonary vein carries oxygen-rich blood to the lungs. |
The pulmonary artery arises from the right ventricle of the heart | The pulmonary vein drains blood in the left atrium of the heart. |
The pulmonary aorta divides into one pair of pulmonary arteries. | The pulmonary vein divides into two pairs of pulmonary veins. |
It carries deoxygenated blood, unlike the rest of the arteries. | It carries oxygenated blood, unlike the rest of the veins. |
Wall is thick and elastic. | Wall is thin. |
Semilunar valves are present. | Valves are absent. |
Blood pressure is higher. | Blood pressure is lower. |
So, the correct answer is ‘Both B and C’.
