Interstitial Fluid Flow

Meaning

Interstitial Fluid Flow refers to the movement of fluid, containing nutrients, hormones, waste products, and immune cells, within the interstitial space, the narrow gap between cells in tissues. This fluid acts as the crucial medium for communication and material exchange between the blood capillaries and the cells of the body. Efficient flow is essential for tissue homeostasis, ensuring that cells receive necessary resources and that metabolic byproducts are effectively collected for lymphatic and venous drainage. Compromised interstitial fluid dynamics can lead to localized edema, impaired cellular function, and accumulation of inflammatory mediators.
