Hemodynamics is that part of Biophysics who is in charge of the study of the dynamics of blood on the interior of structures such as arteries, veins, venules, arterioles and capillaries as well as the mechanics of the heart itself through the introduction of thin catheters through arteries in the groin or arm blood. This technique known as cardiac catheterization allows you to know exactly the State of the blood vessels throughout the body and the heart.
