Question

how do you appreciate the mechanism of respiration in our body

Answer 1

the process of breathing involves taking in oxygen rich air and giving out carbon dioxide rich air.the entire process occurs through the action of the various organs of the respiratory system.the respiratory rate or speed of respiration varies with age.a normal pre-school child has a respiratory rate of 20-30 breaths per minute whereas a normal adult has a respiratory rate of 12-20 breaths per minute.the fuel used for respiration is glucose because glucose synthesized during the process of respiration is used for utilization and production of energy. so, respiration is a continuous process which makes us able to meet energy demand of our body. if it comes to halt , the person will die.

Answer 2

Respiration in our body is described below :

1. Respiration is very much important for all the living organisms. By respiration, oxygen is provided to all the parts and cells of our body to perform certain activities necessary for survival.

2. The 1st step involved in respiration is breathing air from atmosphere and then releasing out CO2.

3. Gaseous diffusion that takes place in the membrane of alveoli.

4. Then, gases are transported by blood.

5. Again between the blood and tissues, diffusion of CO2 and O2 occurs.

6. Then, the O2 is utilised by our cells.
