Each 100 ml of human arterial blood carries �P� ml of $O_2$ and �Q� ml of $CO_2$ whereas each 100 ml of venous blood carries �R� ml of $O_2$ and �S� ml of $CO_2$. Choose the values of P, Q, R and S.
- P = 48 ml, Q = 19-20 ml, R = 52 ml, S = 14-15 ml
- P = 19-20 ml, Q = 48 ml, R = 14-15 ml, S = 52 ml
- P = 14-15 ml, Q = 52 ml, R = 19-20 ml, S = 48 ml
- P = 52 ml, Q = 14-15 ml, R = 48 ml, S = 19-20 ml
The Correct Option is B

Breathing and Exchange of Gases
A metabolic process, which is carried out by all living organisms including plants, animals, and humans for the production of energy and to stay alive is Respiration. Except for required anaerobes, every other organism from amoeba to humans needs oxygen for survival. And evolution has reported a number of systems that allows the exchange of gases in organisms.
There are two types of respiration such as;
- Aerobic respiration — to produce energy, it occurs in the presence of oxygen
- Anaerobic respiration — to produce energy, occurs in the absence of oxygen
Breathing can be simply derived as the process of inhaling oxygen gas from the atmosphere and exhaling the carbon dioxide gas back into the atmosphere is termed breathing and the process is commonly known as respiration.
