What we’ll talk about... Histological structures of conducting airways. Histological structures that facilitate gas exchange. Properties of alveoli that control ventilation. Macrophages and handling of foreign particles. Rate of gas diffusion between air and blood is related to the surface area and thickness of the interface. Air. Blood. O2.
1. Ciliated columnar cells: The most. common type with hundreds of cilia on its apical surface. They also possess microvilli. Fig.2: Cilia (C), and some microvilli (MV), on the apical surface of the columnar cells of the respiratory epithelium.
Development of the lung and pleura. The epithelial components of the lung are derived from the endoderm, while the cartilageous, muscular, and connective components come from the surrounding splanchnic (visceral) mesoderm. The lungs expand in the pleural cavities surrounded by the parietal and visceral pleura.
The respiratory system contains a proximal conducting portion that connects the exterior of the body with the distal respirator y portion where exchange of gases between air and blood occurs.
