Question

Explain the mechanism of breathing in human beings through a flowchart

Answer 1

Answer:

The air from the bodily cavity passes to the throat, that ends up in the trachea, through a slit referred to as speech organ. The trachea runs down the neck and divides into 2 bronchi, that lead into the lungs and any divide into smaller bronchioles. the tiniest bronchioles terminate into alveoli

Answer 2

When we inhale the intercostal muscles (between the ribs) and diaphragm contract to expand the chest cavity. ... When we exhale the diaphragm and intercostal muscles relax and return to their resting positions. This reduces the size of the thoracic cavity, thereby increasing the pressure and forcing air out of the lungs.
