Question

how is oxygen and carbon dioxide transport in human being​

Answer 1

Gas Transport in the Human Body
Once the oxygen diffuses across the alveoli, it enters the bloodstream and is transported to the tissues where it is unloaded, and carbon dioxide diffuses out of the blood and into the alveoli to be expelled from the body.

Answer 2

♥ Transport of oxygen - Haemoglobin present in the blood takes up the oxygen from the air in the lungs . It carries the oxygen to tissues which are deficient in oxygen before releasing it .

♥ Transport of carbon dioxide - Carbon

dioxide is more soluble in water .

Therefore , it is mostly transported from

body tissues in the dissolved form in our

blood plasma to lungs . It diffuses from

blood to air in the lungs .
