difference between systole and diastole.

SYSTOLE:

• It is the contraction phase of the cardiac cycle of the heart.
• In the systole stage, when the heart contracts, it pumps the blood from the heart chambers into the aorta and a pulmonary artery.
• The blood pressure of the systole stage is high for a normal person, it is 120.
• The systolic pressure undergoes considerable fluctuations at different conditions like the extent of work done by heart.

DIASTOLE:

• It is the relaxation phase of the cardiac cycle of the heart.
• In a diastole stage, when the heart relaxes, it allows the heart chambers to be filled with blood from vena cava and pulmonary veins.
• The blood pressure of the diastole stage is low. for a normal person it is 80.
• The diastolic pressure undergoes much less fluctuations in health and remains within a limited range.
