Radius. Length only changes with weight loss, gain or while one is growing. (from infancy to adult)
A blood vessel's radius has a larger effect on the body than the vessels length because more blood can flow through a larger blood vessel. A change in the radius will have more of a affect.
Use the analogy of a hose. When the pressure is high a small bore hose will act to limit the flow but at a lower pressure the radius is hardly a factor. So arteries which have a much higher pressure are more affected by radius than lower pressure than the low pressure venous system.
The turning radius of a vessel is a mathematical computation used to determine the turning circle of the vessel during anchoring in order to check if the anchor is dragging. It can be computed by adding the length of the anchor chain to the overall length of the vessel and subtracting the length between bridge and aft.
The relationship between blood flow through a vessel and the radius of the vessel can be expressed as BF=1/pi r4 (where pi is equal to 3.14.....). So a change in the radius of a vessel has a large effect on the blood flow through the vessel.
They include the radius of the blood vessel, the length of the system, and the viscosity of the blood.
blood vessels lengthen by miles
Physio Ex Answer: When the right vessel radius was increased the flow rate increases.
Laminar flow is the free-flowing blood in the middle of the vessel. Therefore, larger the radius of vessel, more the laminar flow. Smaller the radius of vessel, lesss the laminar flow. Laminar flow is directly reltated to the radius of a vessel.
It is Q= (Pi * Change in P * r4)/ 8nl Where: Q= Blood Flow Pi= Pi value 3.14 P=Pressure difference btw ends of vessels r= radius n= viscosity l= length of vessel
something maybe blocking it like...your finger,rock,cell.
resistance occurs as the blood flows away from heart through the vessels in the peripheral systemic circulation a term known as peripheral resistance. Viscosity of the blood (thickness) ,vessel length (distance) and vessel diameter (blood vessel radius) are three factors
Calculating the radius of dish end size from the pressure vessel diameter is easy. All you have to do is add the blank radius by scaling the drawing from the side and you add five percent.
