What else can I help you with?
What pumps blood away from heart?
Arteries carry blood away from the heart.
Is the Systolic pressure is a measure of blood pressure when the ventricles relax and fill with blood?
No. I think the systolic pressure is when ventricles constrict and the blood goes out , while the diastolic pressure is when ventricles relax and fill with blood.
Ventricle force blood directly into what?
The ventricles contract and force the blood under pressure, past the semi lunar valves into the arteries. The closing of the bicuspid and tricuspid valves prevents back flow. At the same time the atria and ventricles relax and blood begins to flow back into them from the veins.
What part of the blood is atria and ventricles?
The Atria and Ventricles are parts of the heart not the blood. The Atria is the upper chambers of the heart and the Ventricles are the lower chambers of the heart.
Does blood enter the heart through the ventricles?
No. The blood is always pumped in one direction.
What are the blood vessels lying directly on the heart called?
ventricles
In the human heart the muscular structure of the ventricles enables them to?
Pump blood directly to the atria.
What is the phase of ventricular relaxation?
Yes, when the AV valves open and blood begins to enter the ventricles they are in isotonic relaxation. This is why the pressure does not increase in the ventricles during this time.
Does the atrium pump blood to all parts of the body?
No, because the left and right atria are the collecting chambers. They hold theblood until it can enter the ventricles. The ventricles are the pumpingchambers. They cause the blood to move around the body.
What two things enter the blood stream directly from the stomach?
Caffeine and alcohol enter directly from the stomach.
What pumps blood away from heart?
Arteries carry blood away from the heart.
When the ventricles contract blood flows from the right ventricles to what?
The right ventricle pumps blood to the lungs.
Is the Systolic pressure is a measure of blood pressure when the ventricles relax and fill with blood?
No. I think the systolic pressure is when ventricles constrict and the blood goes out , while the diastolic pressure is when ventricles relax and fill with blood.

Why the atria have less muscular walls than ventricles?
the atria dont have to move blood very far, just to the ventricle directly below them, but the ventricles have to move blood a lot farther, especially the left, since it pushes blood throughout the entire body, so it needs a lot of muscle to do this.
What part of the blood is atria and ventricles?
The Atria and Ventricles are parts of the heart not the blood. The Atria is the upper chambers of the heart and the Ventricles are the lower chambers of the heart.
