What is respiration in human being? |
|
Answer» It is the cetabolism process in which food is oxidised which is present in the form of glucouse to get energy in the form of ATP.●C6H12O6+6O2===6CO2+6H2O+38molecule ATP Respiration in human beings\tAir is taken in through nostrils and the air is filtered while passing through the nostrils by fine hairs and mucus that line the passage.\tFrom nostrils air passes to throat where rings of cartilages are present to ensure that air passage does not collapse.\tAir reaches lungs from throats and within the lungs the passage divides into smaller and smaller tubes ending into balloon-like structure called alveoli.\tNetwork of blood vessels are present in the alveoli.\tDuring breathing air is sucked into the lungs and fills the expanded alveoli.\tThe oxygen in the alveolar air is taken by the blood vessels after releasing carbon dioxide collected from all the cells of the body in the alveoli.\tLungs contain a residual volume of air during the breathing cycle.\tRespiratory pigments present in the body take up oxygen from lungs and transport to all the cells of the body.\tHemoglobin is the respiratory pigment of human beings present in the red blood cells which has high affinity for oxygen.\tAs carbon dioxide is more soluble in water than oxygen so it is transported mostly in the dissolved form in our blood.\xa0 |
