Question

When blood moves through the body it travels in a circular pattern. The general pattern of blood flow follows which sequence of vessels as it leaves the heart?

A) veins, venules, capillaries, arterioles, arteries B) veins, capillaries, venules, arterioles, arteries C) arteries, arterioles, capillaries, venules, veins D) arterioles, arteries, capillaries, venules, veins E) arteries, veins, venules, arterioles, capillaries

Answer 1

Option C) arteries, arterioles, capillaries, venules, veins.

Step-by-step explanation:

We know that heart is the organ of our body which pumps blood throughout the body. And this blood is carried by different blood vessels that are arteries, arterioles, capillaries, venules, veins.

1. The arteries carry blood away from the heart.
2. These arteries branches into smaller vessels, these smaller units of arteries are called arterioles.
3. These artioles further branch into tiny capillaries, where nutrients and wastes are exchanged by different part of the body.
4. After exchange of waste and nutrients these capillaries combine with other vessels that exit capillaries and forms venules, these are small blood vessels that carry blood to a vein.
5. Ultimately these veins a larger blood vessel that returns blood to the heart.

Result: The correct series for the blood flow after the heart is arteries-arterioles-capillaries-venules-veins.
