Question

In which of the following points pulmonary artery is different from a pulmonary vein?
A. Its lumen is broad
B. Its wall is thick
C. It has valves
D. It does not possess endothelium

Answer 1

Hint:- The pulmonary artery in most cases contains deoxygenated blood from the coronary heart to the lungs while the pulmonary vein usually includes oxygenated blood from the lungs to the coronary heart, or so that they form of thought. A pulmonary artery has a pretty much smaller lumen and fairly thicker walls as compared to a pulmonary vein, demonstrating that a pulmonary artery has a smaller lumen and generally thicker walls as compared to a pulmonary vein in a major way.

Complete Answer:- The blood inside the pulmonary artery essentially is beneath for all intents and functions much less strain since it essentially is handiest being pumped a quite quick distance to the lungs and so does no longer want a virtually thick wall, or so they thought. The aorta gets blood under truly more stress from the effective left ventricle and so truly desires a sort of thicker wall in a quite principal manner. The pulmonary valve form of is the semilunar valve of the coronary heart that commonly lies between the right ventricle and the pulmonary artery, which essentially indicates that the blood in the pulmonary artery is below form of less pressure since it for all intents and functions is best being pumped a specifically quick distance to the lungs and so does no longer want a commonly thick wall in a kind of principal manner. Valves for the maximum element are used to surely prevent backflow of blood, demonstrating that valves genuinely are used to save you backflow of blood, or so that they form of the idea. The pulmonary vein kind of carries oxygenated blood from the lungs to the left facet of the heart, from the pulmonary circulation in a subtle manner. The heart contraction mainly is sufficient to essentially preserve the blood flowing as the space between the lungs and back to the heart essentially is minimum in comparison to the systemic stream, or so that they for the maximum component thought. So, the pressure of the coronary heart exerting is sufficient to kind of keep the blood in a single direction in a diffused way.
The pulmonary artery is different from the pulmonary vein as its wall is thick.

Hence, the correct answer is option B.

Note:- The pulmonary arteries and the pulmonary veins basically are the vessels of the pulmonary circulation; which truly way they are chargeable for wearing the oxygenated blood to the coronary heart from the lungs and wearing the deoxygenated blood from the coronary coronary heart to the lungs in a subtle way.
