When is the speed of blood slowest in blood vessels?
Veins are where the blood flow is the slowest. Blood flow velocity decreases from the aorta to the arteries to capillaries.
What is the relationship between river depth and width and velocity of flow?
Manning equation if the hydraulic radius decreases then the velocity decreases
What is the relationship between flow rate pressure?
With the increase in flow rate the velocity of the fluid increases. and with the increase in velocity the pressure decreases, because there will be pressure drop (Refer Bernoulli's Theorm). So with increase in Flow rate the pressure decreases.
Does velocity of blood decreases as blood flows from the aorta towards the capillaries?
Yes
What has the most important effect on blood velocity?
Blood viscosity is the most important efect on blood velocity. Viscosity meaning how thin or thick the blood is. Velocity meaning the flow of blood. If the blood is too thick it's velocity will be slow. If the blood is thin, the blood will flow faster.
Where the velocity of blood flow is the lowest?
capillaries!
What is an ultrasound technique used to detect and measure blood-flow velocity?
This technique is a form of Doppler measurement referred to as Blood Flow Imaging (BFI). It can indicate blood flow directionally in addition to measuring velocity.
What decreases peripheral resistance to blood flow?
Vasodilation and decreasing blood viscosity
The velocity of blood flow is highest in the?
Pulmonary Vein
As the blood moves away away from the heart does the blood pressure increase or decrese?
The pressure decreases as it moves away from the heart.
Do velocity of blood flow in arteries become faster in big area?
no
What does a VAD do?
The VAD decreases the workload of the heart while maintaining adequate blood flow and blood pressure.
