Question

what are blood vessles?​

Answer 1

Answer:

Blood vessel - a vessel in the human or animal body in which blood circulates.

• The vessels that carry blood away from the heart are called arteries, and their very small branches are arterioles.

• Very small branches that collect the blood from the various organs and parts are called venules, and they unite to form veins, which return the blood to the heart.

• Capillaries are minute thin-walled vessels that connect the arterioles and venules; it is through the capillaries that nutrients and wastes are exchanged between the blood and body tissues.

Summary:

Blood vessel is a tube through which the blood circulates in the body. Blood vessels include a network of arteries, arterioles, capillaries, venules, and veins.
