Question

Name the three kinds of blood vessels found in human beings. With the help of a suitable diagram, differentiate between them.

Answer 1

Arteries	Veins	Capillaries
Arteries have thick elastic and more muscular walls.	Veins have thin and less muscular walls	Capillary is a narrow blood vessel whose walls have a thin layer of endothelium cells
Arteries carry oxygenated blood(except pulmonary arteries) away from the heart to all of the body’s tissue	Veins carry deoxygenated blood(except pulmonary vein) from tissues to heart.	Capillaries are the terminal branches of arteries, which rejoin to form a vein.
