This energy is derived from the catabolism of various components of food, e.g. (inhalation and exhalation) o Gaseous exchange – the exchange of oxygen and carbon dioxide across a gaseous exchange surface. Expiration : CO given up by venous blood in the lungs is sent out to exterior. Inspiration : Oxygen from fresh air taken by lungs and diffuses into the blood. BREATHING AND EXCHANGE OF GASES * Oxygen is utilized by the organisms to indirectly break down nutrient molecules like glucose and to derive energy for performing various activities. Solution: Vital capacity is defined as the maximum volume of air a person can breathe in after a forced expiration or the maximum volume of air a person can breathe out after a forced inspiration. There is very little transport of gases from one plant part to another . What is its significance? … Respiration involves the following steps: (i) Breathing or pulmonary ventilation by which atmospheric air is drawn in and CO2 rich alveolar air is released out. as breathing. * Carbon dioxide which is harmful is also released during the above catabolic reactions. Chapter 17 Breathing and Exchange of Gases 1. Define vital capacity.
