Learn about the anatomy and physiology of the respiratory system in this 29-minute lecture that covers epithelial cell types, nerve innervation, receptors, and smooth muscle function across the respiratory tract. Explore the structure of the trachea, bronchi, lungs, diaphragm, and airway branches, including specialized cells like Clara cells, basal cells, and goblet cells. Understand the mechanics of breathing through concepts like transpulmonary pressure, compliance, pulmonary fibrosis, and vital lung capacity. Examine how air moves through convection and diffusion, the function of the diaphragm and respiratory muscles, and the measurement of respiratory parameters using spirometry. This comprehensive overview also touches on conditions like asthma and the importance of structures like alveolar ducts, capillaries, and elastic fibers in respiratory function.
