KINE 3000 Lecture Notes - Lecture 18: Vascular Resistance, Blood Vessel, Cardiac Output
Document Summary
Responsible for delivery of oxygen rich blood to all of the tissues within the body. Left side of heart does not send blood equally to all of the body parts, it shifts the distribution of blood around when a situation changes, and one body part needs more blood than the other. Left side of heart pumps out 5l of blood/min and right side of blood needs to also pump out 5l of blood/min. Macro circulation: big blood vessels that help with arterial/ venules embedded within a certain organ (arteries, veins) Cardiac output= mean arterial pressure- right arterial pressure/ total peripheral resistance. Beginning is aortic pressure and end is right atrial pressure (this is known as the pressure difference) Only vascular parameter that is homeostatic ally regulated. 100mmhg is ideal value for our body to achieve good diffusion for out brain to achieve. Will always sacrifice map to make sure diffusion in our brain is good.
