Respiratory Physiology Gas Exchange

This lecture provides an in-depth exploration of respiratory physiology, focusing on its role in homeostasis and gas exchange. Topics include the mechanics of oxygen and carbon dioxide diffusion, partial pressure gradients, and the critical relationship to alveolar structure. It examines oxygen and carbon dioxide transport via hemoglobin and ventilation-perfusion dynamics, incorporating clinical perspectives such as hypoxemia and COPD. The impact of lifestyle factors like smoking is...
