Stage one > general diastole
All muscles of the heart are relaxed
Stage two > atrial systole
Atria contract to push blood into the ventricles
Stage three > ventricular systole
Ventricles contract to pump blood into the blood vessels
Stage four > repeat
An area of the heart can be in two states: - systole, a state of contraction/depolarisaton and diastole, a state of relaxation/repolarisation.
There are three stages to the flow of blood which occur in a continues cycle (i.e. One comes after the other but none start it:
Diastole
Atrial systole
Ventricular systole
The four main stages are:
things that could affect the blood flow through the heart
Circulation of the blood
The flow of blood from the heart to the lungs and back to the heart is called pulmonary circulation.
Blood flows through veins to get to the heart. Arteries are blood vessels for the blood to leave the heart once it has been oxygenated.
there are two main veins that makes the blood flow toward the heart which are the superior vena cava and inferior vena cava.
the heart is a double pump The heart pumps deoxigenated blood from the body through the heart and then through the lungs the back to the heart.
trace blood flow through the kidney from the renal artery to the renal vein? blood flow through kidney from renal artery to the renal vein
Toward the heart.
The heart is a pump and move blood through the blood vessels.
Yes, blood flows into the heart via veins. Blood flows away from the heart in aryteries.
