Question

Difference between arteries veins and capillaries 0

Answer 1

Arteries, veins and capillaries

There are three main types of blood vessels:

arteries take blood away from the heart to the body organs and tissues. The artery wall is thick and muscular so it can withstand the high pressure of the blood being pumped directly from the heart

capillaries are tiny, thin-walled vessels which form a network to take blood through the organsand tissues

veins collect blood from the capillaries in the body and return the blood to the heart. The wall of the veins are thin, the blood is at a much lower pressure. To prevent the backflow of this lower pressure blood the veins contain valves

VIENS:-

{1} they carry blood towards the heart from the organs.

{2} they are comparitively slim.

{3} bolld flows at high pressure.

{4} have valves in them.

{5} carry de-oxygenated blood

{6} execption:-pulmonary vien

ARTERIES:-

{1}carry blood away from heart to organs.

{2} comparitively thick

{3} low pressure

{4} valves are absent

{5} carry oxygenated blood  

{6} exception:- pulmonary artery

CAPILARIES:-

{1} link arteries to veins

{2} carry mixed blood

{3} medium pressure

{4} normal walls of squamous epithilium

{5} no valves are present
