Download free printable worksheets Biology pdf of CBSE and kendriya vidyalaya Schools as per latest syllabus in pdf, CBSE Class 11 Biology Worksheet - Biology Breathing & Exchange Of Gases - Practice worksheets for CBSE students. Chapter 17 Breathing and Exchange of Gases 1. 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. * Carbon dioxide which is harmful is also released during the above catabolic reactions. In the lungs where O2 moves from the air of the lungs into the bloodstream (CO2 moves in opposite direction)! Oxygen is required for catabolic processes and carbon dioxide is released in the process. Second, plants do not pr esent gr eat demands for gas exchange. Breathing and Exchange of Gases 1. 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. In exchange and transport of resiratory gases O 2 and CO 2 both are transported, in this blood play important role. Expiration : CO given up by venous blood in the lungs is sent out to exterior. Breathing and Exchange of Gases We need energy to perform various activities. In a capillary bed elsewhere in the body where the opposite gas exchange happens - O2 diffuses out of There is very little transport of gases from one plant part to another . Contraction of tergo - … This energy is derived from the catabolism of various components of food, e.g. 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.
