Question

Which one of the following is a CORRECT statement?

a)Group of answer choices Veins are more distensible than arteries.

b)Blood pressure is higher in veins than in arteries since blood must be returned to the heart.

c)The walls of veins are made up of two distinct layers of tissues.

d)Veins have a smaller lumen than arteries.

e)Veins carry blood to the capillaries of the body.

Answer 1

Answer:

The correct answer will be Option-A

Explanation:

The systemic circuit system of the circulatory system contains three types of blood vessels: capillaries, veins and arteries.

The arteries and veins although are blood vessels but they are show differences as:

1. Blood Pressure: The blood pressure in the arteries is higher than veins as arteries carry the blood away from the heart to the body whereas veins bring the blood from the body to the heart.

2. Size of Lumen: Arteries possess the high amount of smooth muscle cell and connective tissue which decreases the lumen of the arteries as compared to the veins.

3. Blood vessel composition: Both blood vessels are composed of three layers.

4. Distensibilty: The veins are more distensible than arteries as they are more compliant and can carry more amount of blood than arteries without rupturing.

This shows that the selected option is the correct answer.
