Microvascular permeability

Microvascular permeability refers to the ability of small blood vessels, called capillaries, to allow substances like water, nutrients, and waste products to pass in and out. This process is essential for delivering nutrients to tissues and removing waste. Permeability can vary depending on the body's needs or in response to injury or inflammation, where vessels become more "leaky" to enable immune cells and fluids to reach affected areas. Maintaining appropriate permeability is crucial for healthy tissue function, while excessive or reduced permeability can contribute to medical conditions such as swelling, edema, or impaired healing.
