Which is more likely to occur a change in blood vessel radius or a change in blood vessel length?
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.
What else can I help you with?
Why is blood vessel radius more likely to change than blood vessel length?
Radius. Length only changes with weight loss, gain or while one is growing. (from infancy to adult)
Why would blood vessel radius have a larger effect on the body than vessel length?
Blood vessel radius has a larger effect on the body because changes in radius significantly impact blood flow resistance, which affects blood pressure regulation and delivery of oxygen and nutrients to tissues. Vessel length, on the other hand, has a smaller direct effect on blood flow resistance and overall cardiovascular function.
What is vessel turning radius?
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.
What Two major factors affecting blood flow rates?
They include the radius of the blood vessel, the length of the system, and the viscosity of the blood.
How does obesity change blood vessel length?
blood vessels lengthen by miles
Factors that affect vascular resistance?
Vascular resistance is influenced by factors such as vessel radius, vessel length, blood viscosity, and vessel compliance. Changes in these factors can impact the resistance to blood flow in the vasculature, affecting blood pressure and overall circulatory function.
How do you calculate turning circle for vessels at anchor?
To calculate the turning circle for vessels at anchor, you first determine the vessel's length and the distance from the pivot point (usually near the center of the vessel) to the bow and stern. The turning radius can be estimated using the formula: Turning Radius = (Length of Vessel / 2) + Drag Distance, where the drag distance accounts for the effects of wind and current. By plotting the turning circle on a nautical chart, you can visualize the area the vessel would occupy while turning, considering these external forces.
What happened to the rate as the right vessel radius was increased?
As the right vessel radius increased, the rate of flow in the vessel also increased. This is because as the radius of a vessel increases, the cross-sectional area for fluid flow also increases, allowing more fluid to pass through per unit of time. This relationship is described by Poiseuille's law for laminar flow in a cylindrical vessel.
What is the formula for poiseuille's law?
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
What is the affect on blood flow on the radius vessels?
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.
What would trigger a change in blood vessel length?
something maybe blocking it like...your finger,rock,cell.
What factors influences resistance to blood flow in the arteries?
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
