What is diostolic & siastolic pressure . |
| Answer» The diastolic blood pressure is the pressure the blood exerts within the arteries in between heartbeats, that is, when the heart is not actively ejecting blood into the arteries.When the heart is actively beating (an event called “systole”), it is ejecting blood out into the arteries. This dynamic ejection of blood into the arteries causes the pressure within the arteries to rise. The peak blood pressure reached during active cardiac contraction is called the systolic blood pressure. | |
