respiration class 10 pdf

(i) In insects there occurs a system of tiny holes and air tubes all over the body these tiny holes or openings are called as spiracle. It is 1.5 liters. Sudden contraction of diaphragm along with loud closure of glottis causes, Sudden and violent expulsion of air through mouth and nose is called a, the slow decomposition of organic matter into simpler substances in the presence of enzymes is known as. Practice test sheets for Class 10 for Science made for important topics in NCERT book 2020 2021 available for free... Download syllabus for Class 10 Science issued by CBSE and NCERT for 2021. When oxidation of food takes place in presence of molecular oxygen. it is called as aerobic respiration. (i) Inhalation: When air is breathed in, the diaphragm and muscles attached to the ribs contract due to which there occurs expansion of chest cavity, it results increase in volume of chest cavity thus the air pressure decreases and air from outside rushes into the lungs and alveolar sacs get filled with air containing oxygen. Displaying respiration for class 10 PowerPoint Presentations. It includes metabolic processes by which larger molecules are broken down into simpler molecules, The process by which assimilated food is oxidized and energy is released is called as respiration. In this process oxygen from air is taken in, this oxygen reacts with food molecules present in the body cells and burn them slowly to release energy. The process by which organisms obtain oxygen from environment and release carbon dioxide produced during oxidation of food to the outer environment is called as breathing. 8.1 MACHANISM OF GASEOUS EXCHANGE BETWEEN TISSUES AND BLOOD : When the air enters into the lungs through nostrils, trachea and bronchi it enters into the bronchioles, from bronchioles it moves into thin walled alveolar sacs or alveoli. It brings about the conversion of pyruvic acid, fatty acids, fats and amino acids into CO. ; Nasal chamber – which is lined with hair and mucus to filter the air and remove dust and dirt. 0000000898 00000 n (vii) Bronchi: Trachea is branched into two bronchi left and right each of which enters into the lungs. The syllabus for the practical exam is designed by CBSE according to the CCE guidelines. (vi) Overall production of ATP in glycolysis is 2ATP + 6ATP = 8ATP. The oxygen present in air diffuses into the blood and CO, When air is breathed out the diaphragm and muscles attached to ribs relax, which brings about contraction in chest cavity, its volume gets reduced and CO, 8.1 MACHANISM OF GASEOUS EXCHANGE BETWEEN TISSUES AND BLOOD.
