an increased surface area allows for a greater surface area and reduced distance between the blood and the surrounding tissues, thus increasing diffusion capacity of oxygen is known as capillarization.

Capillarization is the process that increases the surface area and reduces distance between blood and tissues, enhancing oxygen diffusion capacity. It occurs in systems like the circulatory system and fish gills.

This occurs in various biological systems, such as the circulatory system and the gills of fish. In the circulatory system, the large surface area of capillaries in the lungs and the alveoli in the lungs allows for efficient gas exchange between oxygen and carbon dioxide. In the gills of fish, the folded surfaces provide a large surface area for oxygen and carbon dioxide exchange with the water.
