Pulmonary Anatomy & Physiology
Structure and functional dynamics of the respiratory system, gas exchange, regulation of breathing, and acid-base regulation.
Lessons
Structure and Functional Dynamics of the Respiratory System
Upper and lower respiratory anatomy, conducting vs respiratory zones, epithelial types and PCCE, thoracic cavity and lungs, respiratory zone and pulmonary blood flow, pulmonary ventilation, lung volumes and capacities.
Gas Exchange
Energy, temperature and gas pressure, volume and weight laws, ideal gas laws, gas transportation by blood, gas diffusion laws, and the mechanics of external and internal gas exchange.
Regulation of Breathing
