Document Summary
Rate of blood low is important determinant for amount of metabolic acivity in a issue: blood low = pa pv / r, r = viscosity lcap / a2 cap ncap. Radius is regulated, length of the capillary doesn"t change. Flow = volume of luid transported per ime unit. Flow between 2 points is dependent on pressure diference between the 2 points. Flow between 2 points is dependent on the resistance to luid: flow (q) = pressure diference ( p) / resistance (r) Arterioles are the botlenecks of the circulaion, main site of pressure/low regulaion. Vasodilatory compounds (vdc) are produced when atp is made & co2 is produced, regeneraing atp: hydrogen peroxide & protons will be produced, easily move across cell membrane. Many pathways that can carry out funcion, redundancy. If something does go wrong, other redundant pathways that can take over (does make it harder to study) Mammary blood low increases when adenosine is injected.
