Cardiovascular physiology is the branch of biology that focuses on the study of the heart and blood vessels, as well as their functions and interactions in the body. This field of research examines how the cardiovascular system works to pump blood throughout the body, deliver oxygen and nutrients to cells, and remove waste products. It also explores how various factors, such as hormones, nervous system signals, and physical activity, influence the function of the cardiovascular system. Researchers in cardiovascular physiology use a variety of techniques, including imaging technologies, computer simulations, and animal studies, to better understand the mechanisms underlying heart disease, hypertension, and other cardiovascular disorders. Ultimately, the goal of cardiovascular physiology research is to improve our understanding of heart and vascular health and develop new strategies for preventing and treating cardiovascular diseases.
