14. Respiratory System
The respiratory system plays a vital role in gas exchange, facilitating the intake of oxygen and the expulsion of carbon dioxide. The main organs include the nose, pharynx, larynx, trachea, bronchi, lungs, and alveoli, each contributing to the process of breathing and gas exchange. Understanding this system is crucial for recognizing respiratory disorders and the importance of respiration in maintaining homeostasis within the body.

What we have learnt
- The respiratory system is essential for gas exchange.
- Inhalation and exhalation are key processes in the mechanics of breathing.
- Respiration provides oxygen for energy production and removes carbon dioxide from the body.
Key Concepts
- -- Inhalation
- The process of taking air into the lungs, characterized by the contraction of the diaphragm and rib muscles.
- -- Exhalation
- The process of expelling air from the lungs, involving relaxation of the diaphragm and rib muscles.
- -- Alveoli
- Tiny air sacs in the lungs where the exchange of oxygen and carbon dioxide occurs.
- -- Respiration
- The biochemical process of converting nutrients into energy, which requires oxygen and produces carbon dioxide.
- -- Disorders of the Respiratory System
- Conditions that affect normal respiratory function, including asthma, bronchitis, pneumonia, and tuberculosis.
