Vascular function refers to the ability of blood vessels to regulate blood flow, blood pressure, and nutrient exchange throughout the body. Research in this area focuses on understanding how the vascular system works, and how abnormalities in vascular function can lead to various health conditions such as hypertension, atherosclerosis, and stroke. Scientists study factors that influence vascular function, such as endothelial cells, smooth muscle cells, and the autonomic nervous system. By investigating the mechanisms underlying vascular function, researchers aim to develop new treatments and therapies for vascular-related diseases.
