What is the relationship between cross sectional area of blood vessel and velocity of blood flow in that vessel?
Proceeding downstream from the aorta, branching of arterial vessels increases
total cross-sectional area and thus results in diminished velocity of blood flow
from the aorta to the capillaries. Velocity increases from the capillaries to the
large veins with the confluence of vessels and the resulting decrease in total
cross-sectional area.

Explain relationship between the diameter of vessels and the velocity of blood?
As vessel diameter decreases, blood velocity increases due to the principle of conservation of flow rate. This relationship is described by Poiseuille's law, which states that blood flow is directly proportional to the fourth power of vessel radius. Therefore, smaller vessels result in faster blood flow velocities.
What blood vessel has the lowest velocity?
capillaries
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.
How does the law of continuity relate to the velocity of blood flow?
If a pipe's diameter changes over its length, a fluid flows through narrower segments of the pipe faster than it flows through the wider segments. Since the volume of flow per second must be constant through the entire pipe, the fluid must flow faster as the cross-sectional area of the pipe narrows (think of the velocity of water squirted by a hose with and without a nozzle).Based on the law of continuity, you might think that blood should travel faster through capillaries than through arteries, because the diameter of capillaries is very small. However, it is the total cross-sectional area of the capillaries that determines flow rate. Each artery conveys blood to such and enormous number of capillaries that the total cross-sectional area is much greater in capillary beds than in any other part of the circulatory system.For this reason, the blood slows substantially as it enters the arterioles from arteries, and slows further in the capillary beds. As blood leaves the capillaries and enters the venules and veins, it speeds up again as a result of the reduction in total cross-sectional area.
What is relationship between ship and port?
A ship is a vessel, or boat. A port is the place on land where the ship docks to pick up supplies, passengers, ect.
What is the different between ship and a vessel?
a vessel is transported on a ship
Why is knowledge of vectors important to marine people?
Navigators need to be able to combine the marine vessel's velocity with that of the any currents to arrive at the resultant speed and direction. This requires addition of the vectors representing the velocities of the vessel and of the current. It may also be necessary to add the wind velocity.
What blood vessel has the largest cross sectional area?
Veins, the largest vein cavae, are even largest in Diametre than Aorta arteri
What is the difference between motor ship and motor vessel?
There is no difference between the term "motor ship" and the term "motor vessel." The two are commonly used interchangeably.
What is the difference between vessel and voyage?
If your question is related to when you send something in a container vessel and the shipping company gives you a vessel/voyage reference, then Vessel is the name of the ship and voyage is the reference for this specific travel
What is the difference between a brain bleed and an aneurysm?
Hematoma is blood pooled outside the blood vessel, aneurysm is a bulging of a blood vessel.
In the heart the valve between the right lower chamber and its vessel is what valve?
The valve between the right lower chamber of the heart (right ventricle) and its vessel (pulmonary trunk) is the pulminary semilunar valve.
