Question

What are the characteristic features of an artery?
A)Have thick elastic, muscular walls
B)Have thin, non-elastic walls
C)Carry blood from heart to all body parts
D)Both A and C

Answer 1

Hint: Arteries, veins, and capillaries: the three primary forms of blood vessels. Throughout the body, blood vessels pump blood. Blood is transported from the heart by arteries. Back to the heart, the veins return blood. To provide and absorb oxygen, nutrients, and other substances, capillaries surround body cells and tissues.

Complete answer:

Arteries	Veins
1. They have strong, muscular, elastic walls.	1. Have walls that are thin, non-elastic.
2. Lumen is pretty narrow.	2. Lumen is spacious.
3. Bring blood to other body parts from the heart.	3. Carrying blood from other areas of the body to the heart.
4. Bear blood that is oxygenated (except pulmonary artery).	4. Carry blood that is deoxygenated (except pulmonary vein).

The characteristic feature of an artery can be understood better when we compare characters of the artery with the vein, which is shown above.

Hence, the correct answer is option (D)

Note: Systemic arteries can be subdivided into two classes, muscular and elastic, according to the relative compositions of elastic and muscle tissue in their tunic media, their size and the arrangement of the inner and outer elastic lamina. The larger arteries are typically elastic and the smaller arteries tend to be muscular (> 10 mm in diameter) (0.1-10 mm). The systemic arteries deliver blood to the arterioles, and then to the capillaries, which exchange nutrients and gases.
