Explain both in detail
Answers
Answer:
The alveoli are where the lungs and the blood exchange oxygen and carbon dioxide during the process of breathing in and breathing out. Oxygen breathed in from the air passes through the alveoli and into the blood and travels to the tissues throughout the body
t is the amount of air remaining in the lungs at the end of a normal exhalation. It is calculated by adding together residual and expiratory reserve volumes. The normal value is about 1800 – 2200 mL.
Answer:
alveoli are the very thin vasuclarised bag like structure present in human lungs. they are about 300 million in number and function is to carry out diffusion of O2 and CO2 with blood.
RESIDUAL VOLUME is the amount the air that left in the lungs after a forceful expiration
its value is 1100-1200ml
it prevent collapsing of lungs surface
hope u like just give a big thumps up✌️⚡
