Which of the following is known as the energy currency of the cells in biology?
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.
(c) What are tiny filters S known as?
(d) Name (i) liquid U (ii) structure V (iii) tubes W, and (iv) tube X.

What is common between extensive network of blood vessels around walls of alveoli and in glomerulus of nephron?
Which of the following statement(s) is (are) true about respiration?
- During inhalation, ribs move inward and the diaphragm is raised
- In the alveoli, exchange of gases takes place i.e., oxygen from alveolar air diffuses into blood and carbon dioxide from the blood into the alveolar air
- Haemoglobin has a greater affinity for carbon dioxide than oxygen
- Alveoli increase surface area for the exchange of gases
During respiration exchange of gases take place in
