RESPIRATORY SYSTEM

THE RESPIRATORY SYSTEM

It absorbs oxygen into the body and releases carbon dioxide. The lungs and the trachea are organs of the respiratory system.

There are two processes involved in respiration: pulmonary ventilation and gas exchange.

• PULMONARY VENTILATION is the movement of air into and out of the lungs. This process is performed by two movements inspiration and expiration.
• GAS EXCHANGE take place in the alveoli.During this porcess, oxygen from the outside air passes into your blood and carbon dioxide which is in the blood passes to your lungs and leaves your body.

 

Now, it is time to have a look how respiration is performed.
