โ Lungs are situated in the thoracic chamber which is anatomically an air-tight chamber.
โ The thoracic chamber is formed dorsally by the vertebral column,ventrally by the sternum, laterally by the ribs and on the lower side by the dome-shaped diaphragm.
โ The anatomical setup of lungs in thorax is such that any change in the volume of the thoracic cavity will be reflected in the lung (pulmonary) cavity.
โ Such an arrangement is essential for breathing,as we cant directly alter the pulmonary volume
โ Lungs are covered by a double layered pleura with pleural fluid between them.It reduces friction on the lung-surface.
โ Outer pleural membrane is in close contact with the thoracic lining Inner pleural membrane is in contact with the lung surface.

Alveoli are the primary sites of exchange of gases.
Gaseous Exchange in Lungs
โ At alveoli level, gaseous exchange occur through respiratory membrane (diffusion membrane) which is 0.2 mm thick (total thickness is much less than a mm).
โ ๐๐ ๐ฐ๐ผ๐ป๐๐ถ๐๐ ๐ผ๐ณ ๐๐ต๐ฟ๐ฒ๐ฒ ๐น๐ฎ๐๐ฒ๐ฟ๐:
(i) Alveolar epithelium (thin squamous epithelium)
(ii) Basement substance in between them (composed of a thin basement membrane supporting the squamous epithelium and the basement membrane surrounding the single layer endothelial cells of capillaries)
(iii) Endothelium of alveolar blood capillaries
โ Exchange of gases also occur between blood and tissues.
โ O2 and CO2 are exchanged in these sites by simple diffusion mainly based on pressure/concentration gradient
โ Pressure contributed by an individual gas in a mixture of gases is called partial pressure and is represented as pO2 for oxygen and pCO2 for carbon dioxide.
