Question

how is Oxygen and carbon dioxide transported in human being?
​

Answer 1

The two main gases exchanged are oxygen and carbon-dioxide. Oxygen is absorbed by the blood capillaries from the lungs alveoli by diffusion while carbon-dioxide is absorbed by the lungs alveoli from blood capillaries by diffusion. ... Oxygen is transported from lungs to the body cells in the form of oxy-hemoglobin.

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 .
