It is a major component of the cardiovascular system and is important for the performance of all the functions of the cardiovascular system.
Blood pressure is needed to maintain circulation in the body so that oxygen and other nutrients can be transported to the cells. When the blood pressure is too high, it can damage the tissues and cells on the body.
It is one of the most widely recorded physiological functions of the body.
When the heart contracts blood pressure increases. But as the heart relaxes in preparation for the next contraction, blood pressure decreases. The result is that a person’s blood pressure changes in a periodic fashion, each period corresponding to a single heartbeat.
Physicians refer to the maximum of this pressure as the systolic blood pressure and it the minimum pressure as the diastolic pressure. Systolic pressure means that the peak pressure reached in the arterial system.
If the blood were not under the same pressure it could just stay where it is stagnant, neither nourishing nor cleansing the cells of the body, so that within about 7 minutes first they and the people would die.
