Q-Explain the mechanism of breathing??
Hi,
Breathing is a continuous process that involves both inhalation and exhalation. The process of taking in oxygen-rich air is known as inhalation, while the process of releasing carbon dioxide-rich air into the atmosphere is known as exhalation.
During inhalation, the diaphragm moves down and the ribs move upwards and outwards, thereby increasing the space in the chest cavity. This leads to the movement of air inside the lungs.
During exhalation, the diaphragm moves to its former position and the ribs move downwards and inwards, thereby reducing the size of the chest cavity. This leads to the movement of air out of the lungs.
Hope it is clear to you now,
Cheers!!
