Capillary Exchange Process: Oxygen and Nutrient Delivery to Tissues #1821093 (License: Personal Use)

This schematic depicts the microcirculation in capillary beds, highlighting bidirectional diffusion across the endothelial barrier. Red blood cells travel through narrow capillaries, releasing oxygen and absorbing carbon dioxide as metabolic exchange occurs with surrounding interstitial fluid. The diagram emphasizes perfusion dynamics and the role of hydrostatic and osmotic pressures in transcapillary exchange.

Used in medical education, physiology textbooks, and health websites to explain microvascular function; matches user intent for understanding circulatory physiology, gas exchange, or capillary structure-function relationships.
