The understanding respiratory system and its functions is vital for human survival, encompassing a complex network of organs that facilitate breathing and gas exchange.
- The respiratory system begins at the nose and includes crucial organs like the pharynx, larynx, trachea, bronchi, and lungs
- Role of alveoli in gas exchange process is fundamental, as these tiny air sacs enable oxygen intake and carbon dioxide release
- Common respiratory diseases and their causes range from viral infections like influenza to chronic conditions such as asthma and COPD
- The diaphragm plays a crucial role in breathing mechanics by controlling lung expansion and contraction
- Various protective mechanisms exist throughout the system to filter, warm, and moisturize incoming air
