Question

'Breathing cycle is rhythmic where as exchange of gases is a continuous process .' Justify the statement.

Answer 1

Breathing is basically the intake of oxygen which is first inhaled by contraction of diaphragm and relaxation of chest cavity. The oxygen then combines with haemoglobin in the red blood cells and is transported all over the body. Whereas exchange of gases keeps on taking place. Once the oxygen has been inhaled, the carbon dioxide is immediately released.

Answer 2

it is a continuous process which happens in our day to day life and which is also important for exchange of gases (co2 and o2) for surviving and for the production of energy for example (c6h12o6)glucose
