Document Summary

Blood pressure and flow: blood flow, blood pressure, peripheral resistance, flow at different points in systemic circuit, mean arterial pressure = cardiac output x totally peripheral resistance. Principles of blood flow: blood flow or known as ow rate: amount of blood owing through a tissue or organ in given time (ml (cm^3)/min, velocity: distance traveled by blood per unit time (cm/min) Physical principles of blood ow based on pressure and resistance. F (delta)p/r (f = flow, (delta)p = difference in pressure, r = resistance to flow) Flow/flow rate is equal to the pressure gradient. Delta p or p = pressure gradient. Blood pressure (one type of hydrostatic pressure: force that blood exerts against any vessel wall. ; map is fairly similar through all the arteries up to the arterioles: good estimate of systemic blood pressure because it is similar throughout the body except for effect of gravity which causes a lower.
