Respiratory System: Introduction and Anatomy

This lecture covers the basic principles of ventilation and respiration, including the role of ventilation in air movement, the role of respiration in gas exchange, and the anatomy of the lungs, pleura, and airways. It also discusses the structure and function of the respiratory system, emphasizing the convective ventilatory system, gas-liquid interface diffusion, and the circulatory distribution system. The lecture delves into the principles of gas exchange, the anatomy of the thoracic cavity, the functional anatomy of the airways, and the structure of the trachea and major bronchi. It further explores the anatomy of the alveoli, including the respiratory bronchioles, alveolar ducts, and alveolar sacs, as well as the vascular interface within the alveoli.
