Question

✌What are the functions of Capillaries?
✌What are Arteries and Veins?

Explain ^-^

Answer 1

Hey there!

Functions Of Capillaries :)

↪To allow outward diffusion of oxygen into the intercellular fluid and from there into the tissue cells.

↪To allow inward diffusion of carbon dioxide from the intercellular fluid.

↪To allow inward and outward diffusion of substances like glucose, amino acids, urea, hormones, etc.

↪To allow leukocytes to squeeze out through the capillary walls by means of amoeboid movement.


What are Arteries?
↪The blood vessels which carry blood away from the heart and into an organ. Arteries carry fully oxygenated blood(except pulmonary artery).

What are Veins?
↪The blood vessels which carry blood from an organ and towards the heart. Veins carry partially de-oxygenated & CO2 laden blood(except pulmonary vein).

Answer 2

Function of capillaries :-

* It helps in diffusion of substances.

* It also allow diffusion of oxygen and carbon dioxide.


Arteries :-

The blood vessels which carry oxygenated blood away from the heart except pulmonary arteries. They have thick walls.


Veins :-

The blood vessels which carry deoxygenated blood towards the heart except pulmonary veins.
They have thin Walls.


Hope it helps.
