differentiate between arteries and veins what is the importance of capillaries in the circulatory system.

1.Involved in carrying pure, oxygenated blood and nutrient-rich blood.

2.Consists of three distinct layers, which are rigid, thicker and highly muscular.

3.Located deep within the body.

4.Red in colour.

5.Carry blood away from the heart to various parts of the body.

6.High pressure, as the blood flows by the pumping pressure of the heart.

7.Comparatively higher oxygen level.

8.The level of carbon dioxide is low

9.Lumina is narrow

10.Valves are absent

11.Arteries are at a greater risk of certain diseases like angina pectoris, atherosclerosis, etc.

1.Involved in carrying impure, deoxygenated blood

2.Consists of three distinct layers, which are thin and collapsible.

3.Peripherally located closer to the skin.

4.Blue in colour.

5.Carry blood towards the heart from the various parts of the body.

6.Low pressure, as the blood flows by the capillary action of the veins.

7.Comparatively low oxygen level.

8.The level of carbon dioxide is high

9.In upward direction from the body tissues to the heart.

10.Lumina is wide & Valves are present.

11.Veins are less susceptible to diseases such as varicose veins.

Though tiny, the capillaries are one of the most important parts of the circulatory system because it's through them that nutrients and oxygen are delivered to the cells. In addition, waste products such as carbon dioxide are also removed by the capillaries.
