WebPleura of the Lungs. Each lung is enclosed within a cavity that is surrounded by the pleura. The pleura (plural = pleurae) is a serous membrane that surrounds the lung. The right and left pleurae, which enclose the right and left lungs, respectively, are separated by the mediastinum. The pleurae consist of two layers. WebThis slide shows a cross section of the esophagus, the first portion of the digestive tract that leads to the stomach.

"WebThe alveoli are the terminal air saccules of the lungs. Fine pulmonary capillaries surround them. Both are lined by layers of extremely thin epithelium and separated by membranes. In the alveoli the concentration of oxygen is higher than in the capillaries. Therefore oxygen moves passively by diffusion into the capillaries. " - Cross-sectional view of the alveoli

WebFunction. Pulmonary alveoli, where gas exchange occurs, are bubble-shaped and have a high degree of curvature. The surface tension of the moist inner surface is due to the attraction between the molecules in the alveolar fluid and tends to make the alveoli contract. Unchecked, this tendency would result in lung collapse. WebThe gaps between the rings of cartilage are filled by the trachealis muscle - a bundle of smooth muscle, and fibroelastic tissue. Together these hold the lumen of the …

This blood–air barrier is extremely thin (approximately 600 nm-2μm; in some places merely 200 nm) to allow sufficient oxygen diffusion, yet it is extremely strong. This strength comes from the type IV collagen in between the endothelial and epithelial cells. Damage can occur to this barrier at a pressure difference of around 40 millimetres of mercury (0.053 bar). WebThe blood is then transported to the lungs where differences in pressure in the alveoli result in the movement of carbon dioxide out of the blood into the lungs, and oxygen into the blood.
