Do some one explain this please?
By the effect of Autonomic nerv. system or other will increase blood pressure and flow like by vasoconstriction, however in bernoulli's principle, it says that pressure and flow volume will decrease during constriction and increase in dilation...this is what we seen during stenosis or clogging of blood vessels. Simmilarly, in autoregulation--like by vasomotion, blood flow and pressure will decreased by constriction and vice versa..this will agree with bernoulli's but the vasoconstriction/vasodilation effect that the body uses to increase or decrease the blood pressure + flow will not agree with this rule...would you please explain these
One other thing...assume a small capillaries with same crossectional area will branch out from a single arteriole(with higher crossection). I know that the speed at each branches are equal and less than that in the artery/arteriole, but do you think the flow or volume will be same both in the arteriole and at each capillary branches regardless of the area difference? I.e Q1 vs Q2
Artery, Q1.........Arterioles, with Q2.......................branches of capillaries, with Q3
Thank you very much
