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. Second, plants do not pr esent gr eat demands for gas exchange. • 1. 6.4 Gas Exchange! • 2. Also after the chapter you can get links to Class 11 Biology Notes, NCERT Solutions, Important Question, Practice Papers etc. Oxygen is required for catabolic processes and carbon dioxide is released in the process. as breathing. Contraction of tergo - … * Carbon dioxide which is harmful is also released during the above catabolic reactions. Breathing and Exchange of Gases We need energy to perform various activities. (inhalation and exhalation) o Gaseous exchange – the exchange of oxygen and carbon dioxide across a gaseous exchange surface. (ii) Diffusion of gases (O2 and CO2) across alveolar membrane. proteins, carbohydrates, fats, etc. What is its significance? In human for breathing activity nose, phalynx, larynx ,trachea,bronchi and lungs like organs makes togather respiratory system.

Diagphram and intercostal muscel play important role in inspiration and expiration process. BREATHING AND EXCHANGE OF GASES INTRODUCTION EXERCISE - I 1. It is not thin c. It is not permeable to and d. All of these 2. In a capillary bed elsewhere in the body where the opposite gas exchange happens - O2 diffuses out of In the lungs where O2 moves from the air of the lungs into the bloodstream (CO2 moves in opposite direction)! Skin of man cannot act as respiratory organ because a. o Breathing – the mechanical process whereby air moves into and out of the lungs. There is very little transport of gases from one plant part to another . its own gas-exchange needs. It represents the maximum amount of air one This energy is derived from the catabolism of various components of food, e.g. 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. In cockroach inspiration is brought about by a. Breathing and Exchange of Gases 1. Chapter 17 Breathing and Exchange of Gases 1. Define vital capacity. … Chapter 17 : Breathing and Exchange of Gases NCERT Notes For Class 11 Download in PDF POINTS TO REMEMBER Breathing : (External respiration) The process of exchange of O from the atmosphere with CO 2 [110] 2 produced by the cells. 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.
