Question

How do you appreciate the mechanism of respiration in our body ​

Answer 1

Answer:

Mechanism of respiration involves five steps:-

Mechanism of respiration involves five steps:-Breathing or pulmonary ventilation: It involves both inhalation in which an adequate amount of oxygen is taken inside and exhalation involves removal of carbon dioxide with air.

External respiration: This is the exchange of oxygen to the blood and of carbon dioxide from blood to alveoli and is done due to their concentration gradient.

Transport of O2 to tissue: Oxygen binds to haemoglobin and reaches to tissues.

Internal respiration: As the concentration of oxygen is less and carbon dioxide is more in number the haemoglobin release oxygen and is absorbed by the tissue.

Transport of CO2 from tissue:- The carbon dioxide released by tissue transported in the form of bicarbonate, carbamino-haemoglobin and dissolved in the blood reaches to alveoli then diffuse from blood and released out.
