Vascular function refers to how the blood vessels in the body operate to transport blood. This includes the ability of arteries and veins to constrict and dilate, which helps regulate blood flow and blood pressure. Proper vascular function is essential for delivering oxygen and nutrients to tissues and removing waste products. Factors such as exercise, diet, and age can influence vascular function. Healthy habits, like regular physical activity and a balanced diet, can improve the elasticity of blood vessels, promoting better circulation. Conversely, conditions like hypertension or atherosclerosis can impair vascular function, leading to serious health issues.
