What else can I help you with?
What additional factor will be change if the direction of a current flow is change?
direction of magnetic field
How does a Doppler measure blood flow?
A Doppler ultrasound measures blood flow by using the Doppler effect, which involves the change in frequency of sound waves as they reflect off moving red blood cells. When the ultrasound waves are transmitted into the body, they bounce off these cells, and the frequency of the reflected waves changes depending on the speed and direction of blood flow. By analyzing these frequency shifts, the Doppler ultrasound can determine the velocity and direction of blood flow, providing valuable information about cardiovascular health and detecting abnormalities.
Why is the blood going up to the heart does not flow backward because the veins that carry them have what?
Valves are present in veins to prevent the backward flow of blood. These valves help ensure that blood moves in only one direction toward the heart by closing when blood tries to flow in the wrong direction.
Do heart valves control the direction of blood flow?
Yes, heart valves control the direction of blood flow by opening and closing to ensure that blood flows in one direction through the heart. This helps to maintain the efficiency of the heart's pumping action and prevent backflow of blood.
Does the blood in the body flow in an anticlockwise direction?
No, blood flows in a closed circulatory system in the body, typically in a cyclical pattern. It is pumped by the heart through arteries, capillaries, and veins in a continuous loop. The direction of flow is determined by the pumping action of the heart and the structure of the blood vessels.
Direction of blood flow?
forward
If a door in a plane was opened at high altitude which direction would the air flow?
Outwards
Is blood flow in the human body considered to be laminar or turbulent?
Blood flow in the human body is considered to be mostly laminar, meaning it flows smoothly in layers. However, it can become turbulent in certain situations, such as when blood vessels narrow or when there is a sudden change in flow direction.
How is it possible to determine the direction of blood flow from the blood spatter?
human
Why Mississippi river change direction of flow?
200 years ago there was an earthquake in Illinois that caused the flow of the Mississippi river to change direction
Valves to help the direction of blood flow are found in which blood vessels?
Veins.
What is the major function of a valve in the heart?
Valves control the flow of blood. Without them blood could flow backwards.--------------------------Yes, true. Valve would maintain one way traffic for blood right from the heart and to outside parts of the body and form outside to the heart.
What additional factor will be change if the direction of a current flow is change?
direction of magnetic field
Does blood only flow in one direction through the heart?
NO
How does a Doppler measure blood flow?

What four doors control direction of blood flow through?
valves
BLOOD flow in one direction only inside the heart?
yes :)
