Cardiac cycle
One Cardiac cycle= 1 systole and 1 diastole The normal systole pressure is 120mmhg The normal diastole pressure is 80mmhg Systolic pressure When the left ventricle contracts. the pressure ejected, into aorta from the ventricle. This pressure Is called systolic pressure. 120mmhg is the systolic pressure. Diastolic pressure After ventricle relaxation. the aortic valve gets closes, inorder to stop back flow of the blood. The pressure which remained in the aorta is called diastolic pressure. The diastolic pressure is 80mmhg. The total cardiac cycle or heart beat, takes about 0.8 seconds. Stroke volume: The amount of blood pumps into the aorta, by the left ventricle in one contraction is called stroke volume. The cardiac cycle under goes 7 phases. 1. Atrial contraction When the atrium starts contraction, the mitral valve opens into ventricle. While the atrium contracting, The press...
