Arterial blood pressure

Blood pressure
Arterial blood pressure is the force of blood pressure to the walls of blood vessels that contain it, changing every stage of the heart cycle. During ventricular contraction (left ventricular force blood into the aorta) the pressure rises until the top is called the systolic pressure. During the relaxation of the pressure drops, the lowest value is called the diastolic pressure.
Systolic blood pressure generated by the heart muscle that drives the content of the ventricle into the artery that had been terengang. During the relaxation of arteries was bulging because peripheral resistance of arterioles to block all blood flow into the network. The contraction is maintained by vasoconstrictor nerves and controlled by the center in the medulla oblongata vasomotorik. The human circulatory system
