vascular reactivity

Vascular reactivity refers to how blood vessels respond to various factors, such as changes in blood flow, temperature, or chemicals. When you exercise or are exposed to heat, your blood vessels may expand to increase blood flow and deliver more oxygen or nutrients to your muscles. Conversely, they can constrict to reduce blood flow when necessary, such as in response to cold. This ability to adjust is crucial for maintaining healthy blood pressure and ensuring that different parts of the body receive adequate blood supply based on their needs.
