This course provides a detailed introduction to the mechanics of breathing, emphasizing the role of pressure changes in the respiratory system. Designed for medical, physiology, and healthcare students, the course explains how inhalation and exhalation occur, driven by differences in intrapulmonary and intrapleural pressures.

Learners will study the structure and function of the lungs, thoracic cavity, and diaphragm, understanding how their interactions create the pressure gradients necessary for airflow. The course highlights key concepts such as negative and positive pressure, atmospheric pressure, and how changes in thoracic volume affect lung expansion and contraction.

Through clear diagrams, animations, and examples, students will visualize the processes of inspiration and expiration, including the roles of accessory muscles in forced breathing. The course also covers common physiological variations, such as changes in breathing mechanics during exercise or respiratory disorders, helping learners link theory to clinical relevance.
