उत्तर

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.

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.
