Description

Colorized scanning electron micrograph showing the erythrocytes (red blood cells) within the capillary network of an alveola. The alveolar-capillary barrier (or membrane, or blood-air barrier) exists in the gas exchanging region of the lungs. It exists to prevent air bubbles from forming in the blood, and from blood entering the alveoli.

Technical Details

Image collected on a FEI Quanta Family with the following parameters: Magnification: 1800:1 x, Vacuum: High Vac, Voltage: 5 kv, Detector: SE+BSE, and Working Distance: 9 mm.
