the valves
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.
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.
NO
A heart valve stops the flow of blood backwards when the heart muscle pulses. Without the valve there would be no direction to the flow of the blood.
Doppler echocardiography employs a special microphone that allows technicians to measure and analyze the direction and speed of blood flow through blood vessels and heart valves
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.
yes :)
Valvs
toward the heart from the lungs
The heart is the organ that keeps the blood flowing. Valves in the heart ensure the flow is only in one direction.
there are two main veins that makes the blood flow toward the heart which are the superior vena cava and inferior vena cava.
It is important for blood to flow in one direction in the heart because blood can't flow backwards because it has oxygen rich blood and poor oxygen rich blood and these to types of blood cannot mix :)
