The process of exchanging gases, like oxygen and carbon dioxide.

How does respiration occur?

Through mechanisms involving the diaphragm and bronchial tubes.

What are the volumes of air in respiration?

Tidal, inspiratory reserve, and expiratory reserve volumes.

It affects oxygen and carbon dioxide levels in the blood.

Asthma, emphysema, and occupational issues like smoking.

Understanding respiration involves the exchange of oxygen and carbon dioxide in the body, facilitated by the diaphragm, intercostal muscles, and bronchial tubes.
The text highlights the significance of oxygen and carbon dioxide levels in the blood, alongside different air volumes crucial for respiration, while also addressing respiratory disorders like asthma, emphysema, and occupational hazards like smoking and asbestos exposure.
