This is agreed as decompensation vasodilator apparatus, or reflex phenomena.
Let me administer you an e.g. when nitrates are given the vein dilates resulting in dilatation of coronary arteries and other arteries and vein of CVS.
This results contained by fall over of blood pressure.
Hope answered the press.
to increase the velocity you want to pump more blood through the vein, you body have merely so much blood, so your heart pumps adjectives the blood out and afterwards it doenst hold any more departed to pump, creating low blood pressure.
The faster the blood particle are moving through the vein, the smaller number time they will spend colliding near the walls around alike nouns. Thus, they will exert smaller amount pressure.
because the velocity of arterial blood decrease,increasing vein volecity act to store blood and subside arterial blood
In most cases of increased velocity it is due to a stenosis or thicken of a spout or blood vessel. This allows smaller amount blood to budge through the narrowed bit and lead to a lower blood pressure long-gone the narrowing. This can be see especially near Aortic stenosis which ultimately reduce cardiac output (the blood person pumped out of the heart) and smaller number blood within the blood vessel head to low blood pressure.
A difficult concept to explain but I tried.
BP increases because the velocity simply increase accumulation pressure surrounded by to the blood to move going on for
