Question

OK , differentiate between : veins, arteries and capillaries ​

Answer 1

The chief difference between arteries and veins is the job that they do. Arteries carry oxygenated blood away from the heart to the body, and veins carry oxygen-poor blood back from the body to the heart. ... Capillaries are tiny, thin blood vessels that allow oxygen and nutrients to flow to nearby tissue.

Answer 2

Arteries carry oxygenated blood from the heart to the various organs of the body except pulmonary artery

Veins carry deoxygenated blood from the various organs of the body to the heart except pulmonary vein

Capillaries are the smallest blood vessels or arteries which diffuse the nutrional materials from the blood into the surrounding cells
