Respiratory System Concepts Assessment

This video provides an in-depth overview of the respiratory system, highlighting its critical role in breathing and gas exchange. It covers the five main functions: pulmonary ventilation, external and internal respiration, sound production, and smell. The video also details the structures of the upper and lower respiratory tracts, including the nose, mouth, pharynx, larynx, trachea, lungs, bronchi, and diaphragm. Additionally, it explains the conducting and respiratory zones, emphasizing the importance of ventilation and the potential health issues related to improper gas exchange.
