What is the reasons for the observed changes in blood flow velocity in the different regions of the circulation?

The speed velocity of blood flow changes as blood travels through the systemic circulation. This change can be faster or slower. It is fastest where the cross-section area of the vascular bed is least, and slowest where the total cross-section area is greatest. This slow flow allows nutrient-waste exchange.

What can be defined as the rate at which velocity changes?
accelerationThe rate at which velocity changes is called "acceleration".
When does one feel the effects of velocity in a moving vehicle when it is moving uniformly or when its motion changes?
One feels the changes in velocity, or acceleration, when the motion of the vehicle changes.
What changes have been observed in the ecosystem since the salicaria introduction?
alot of changes
What word is the definition of the rate velocity changes with time gravity mass velocity or acceleration?
Force
What is the effect on force if the velocity changes from 5 mph to 10 miles per hour?
Velocity does not affect force.
Acceleration can be defined as the rate at wich velocity?
Acceleration is observed when velocity changes with respect to time. For instance, at t0 an object may be moving with a velocity of 2. At t1, it could be moving with velocity of 4, which means that it has doubled its velocity; thus accelerating. This can also be observed in reverse, where at t0 the velocity is 4 and at t1 the velocity is 2. The object then has decelerated, or has slowed down with respect to change in time.
What happens when velocity changes?
When velocity changes, that means that the object either moves faster, or moves slower, or moves in a different direction. Any of these changes is called "acceleration".
Does the speed of an object change when the speed changes?
Yes. The velocity changes when the direction of motion changes, because the definition of 'velocity' is 'speed and the direction'. If either speed or direction changes, then we say the velocity has changed. Notice that if the direction changes, then the velocity changes even if the speed doesn't. "Velocity" is not just a bigger word that you use for 'speed' when you want to sound smart. They mean different things.
What is it when velocity changes?
When velocity changes, that means that the object either moves faster, or moves slower, or moves in a different direction. Any of these changes is called "acceleration". A force is necessary to cause it.
An object in circular motion is constantly acceleratingtrue or false?
True. It is accelerating because the velocity constantly changes. The velocity constantly changes because the direction changes - and a velocity is made up of a magnitude, and a direction.True. It is accelerating because the velocity constantly changes. The velocity constantly changes because the direction changes - and a velocity is made up of a magnitude, and a direction.True. It is accelerating because the velocity constantly changes. The velocity constantly changes because the direction changes - and a velocity is made up of a magnitude, and a direction.True. It is accelerating because the velocity constantly changes. The velocity constantly changes because the direction changes - and a velocity is made up of a magnitude, and a direction.
Why the speed of an object is constant while the velocity is not?
This is not always the case. But if an object moves in a circle, at constant speed, its velocity will change. Velocity is a vector - consisting of the magnitude (the speed), and a direction. So by definition, if the direction changes, the velocity changes - you have a different vector.
What are acceleration and velocity?
'Velocity' means the rate at which position changes, and the direction in which it changes. 'Acceleration' means the rate at which velocity changes, and the direction in which it changes.
What changes a body's velocity?
A force changes a body's velocity.
How does the change in angle changes the velocity?
Velocity is speed in a direction or speed at an angle. The velocity changes when the speed or angle changes.
How are acceleration and velocity alike and different from each other?
-- both are related to measurements of motion of objects -- acceleration is the rate at which velocity changes
Th rate at which velocity changes?
Velocity changes are referred to as acceleration.
How velocity different from speed?
Velocity is acceleration and direction put together. The velocity of something changes if either acceleration or direction changes. Speed is just the average MPH measure. Velocity is not acceleration and direction put together. In that kind of description, velocity is is speed and direction put together. Velocity is a vector, whose size is the speed.
