What is systolic pressure and the diastolic pressure

Cardiac cycle is the rhythm of role play of the heart as a pump, this pumpcan be divided into two. One is to send the blood to the body, the leftatrium and the left ventricle is responsible for; the other is all parts of the body with low oxygen content of venous return of blood to the lungsfunction, the right atrium and the right ventricle is responsible for.


In other words, the left atrium and the left ventricle is responsible forthe blood, while the right atrium and the right ventricle is responsible forvenous blood.


The blood from the lungs into the Pulmonary veins, into the left atrium,then flow into the left ventricle. When the left ventricle is filled withblood, heart contraction, blood enter the aorta, at which point the highestblood, called the systolic pressure.


After the blood from the left ventricle into the aorta, the heart continues to store blood from the lungs in the left ventricle, right ventricle havestarted stockpiling by various parts of the body back into the blood. So,when body parts stored in the blood when the heart, ventricular diastolicblood pressure the lowest known as diastolic blood pressure.


However, the body‘s blood pressure is not constant, but always in change,but blood pressure is normal and not normal people, the magnitude of changeis different.


Changes in blood pressure like this, sometimes high blood pressure occurs,sometimes the State of low blood pressure can occur.
