Question

Explain the mechanism of gaseous exchange between tissue and blood.

Answer 1

The arteries carry oxygenated blood from the heart to the tissues. The arteries divide into small capillaries. Through very thin wall of capillaries Oxygendiffuse in tissues and CO2diffuse in the capillaries. These capillaries join and form vein which now carries deoxygenated blood from tissue to heart for the purification of blood.

Answer 2

The mechanism of oxygen flow between blood and tissues is given below:

Blood carries oxygenated blood from lungs to other parts of the body. This blood is highly rich on oxygen content whereas the blood flows in tissues has less oxygen becauseit has been takn up for cellular processes.  

Now due to the difference in the oxygen concentration between blood and tissues, oxygen diffuses from blood into the tissues and carbon dioxide from tissues into blood. This deoxygenated blood than moves to lungs for the cleaning process.
