Vascular biology is the study of blood vessels, including their structure, function, and development. It focuses on how arteries, veins, and capillaries work together to transport blood throughout the body, delivering oxygen and nutrients to tissues while removing waste products. Understanding these processes is crucial for addressing various cardiovascular diseases. Research in vascular biology also explores the mechanisms of angiogenesis, the formation of new blood vessels, and how endothelial cells line the blood vessels. This field is essential for developing treatments for conditions like atherosclerosis and hypertension, which can significantly impact overall health.
