(a) Respiration

(b) Hypoxia

(c) Asphyxiation

(d) Breathing

(e) Vital capacity

(a) Respiration — Respiration is the biochemical process of releasing energy by breaking down glucose for carrying out life processes.

(b) Hypoxia — Hypoxia is the deficiency of oxygen reaching the tissue. It may occur due to over crowding with poor ventilation or at high altitudes.

(c) Asphyxiation — Asphyxiation is a condition in which the blood becomes more venous by accumulation of more carbon dioxide and the oxygen supply is diminished.

(d) Breathing — Breathing is a physical process in which the atmospheric air is taken in and forced out of the oxygen-absorbing organs, the lungs.

(e) Vital capacity — Vital Capacity is defined as the volume of air that can be taken in and expelled out by maximum inspiration and expiration. It is 4500 ml.
