How do we breathe ?

😀we take in air through our nostrils. When we inhale air, it passes through our nostrils into the nasal cavity. From the nasal cavity, the air reaches our lungs through the windpipe. Lungs are present in the chest cavity (Fig. 10.4). This cavity is surrounded by ribs on the sides. A large, muscular sheet called diaphragm forms the floor of the chest cavity (Fig. 10.4). Breathing involves the movement of the diaphragm and the rib cage.

This is the respiratory system of a human
