Question

differentiate between artery vein and capillary​

Answer 1

Answer:

$\huge\red{\boxed{\sf Difference }}$

Artery Vein :- Arteries are blood vessels responsible for carrying oxygen-rich blood away from the heart to the body. Veins are blood vessels that carry blood low in oxygen from the body back to the heart for reoxygenation.

Capillary :- Capillaries carry blood away from the body and exchange nutrients, waste, and oxygen with tissues at the cellular level. Veins are blood vessels that bring blood back to the heart and drain blood from organs and limbs.

Answer 2

Answer:

1.Arteries carry blood away from the heart; the main artery is the aorta.

2.Smaller arteries called arterioles diverge into capillary beds, which contain 10-100 capillaries that branch among the cells and tissues of the body.

3.Capillaries carry blood away from the body and exchange nutrients, waste, and oxygen with tissues at the cellular level.

4.Veins are blood vessels that bring blood back to the heart and drain blood from organs and limbs.

5.Capillaries have one layer of cells (the endothelial tunic or tunica intima) where diffusion and exchange of materials takes place.

6.Veins and arteries have two more tunics that surround the endothelium: the middle tunica media is composed of smooth muscle that regulates blood flow, while the outer tunica externa is connective tissue that supports blood vessels.
