vasomotion

Vasomotion refers to the natural, rhythmic constriction and relaxation of blood vessel walls, particularly small arteries and capillaries. This process helps regulate blood flow and pressure, ensuring tissues receive the right amount of oxygen and nutrients. Vasomotion occurs due to coordinated activity of muscle cells in vessel walls driven by nervous signals and chemical signals. It plays a vital role in maintaining overall circulatory health by preventing blood stagnation, promoting efficient exchange of substances, and adapting blood flow to changing needs within different parts of the body.
