प्रश्न
What type of respiration takes place in human muscles during vigorous physical exercise? Give reason for your answer

Anaerobic respiration takes place in human muscles during vigorous physical exercise. This is because oxygen gets used up at a faster rate in the muscle cells than can be supplied by the blood-carrying oxygen.

One of the following organisms does not depend on the simple diffusion of gases for breathing and respiration. This organism is:
There is a pair of bean-shaped organs P in the human body towards the back, just above the waist. A waste product Q formed by the decomposition of unused proteins in the liver is brought into organ P through blood by an artery R. The numerous tiny filters S present in organ P clean the dirty blood by removing the waste product Q. The clean blood goes into circulation through a vein T. The waste substance Q, other waste salts, and excess water form a yellowish liquid U which goes from organ P into a bag-like structure V through two tubes W. This liquid is then thrown out of the body through a tube X.
(a) What is (i) organ P, and (ii) waste substance Q?
(b) Name (i) artery R, and (ii) vein T.

(d) Name (i) liquid U (ii) structure V (iii) tubes W, and (iv) tube X.
