As the pressure in the cuff is released further, the tapping sounds become louder, then soon soften. When the artery is no longer constricted and blood flows freely, the sounds disappear. The cuff pressure reading at the last sound heard is recorded as the diastolic pressure. away from the heart. As the blood courses through the system in less elastic vessels—arterioles into capillaries into venules into veins—blood pressure drops. When the blood finally returns to the right atrium via the venae cavae, the pressure behind it is almost zero.
Diastole (die-ASS-te-lee): Period of relaxation and expansion of the heart when its chambers fill with blood. Aorta (ay-OR-ta): Main artery of the body. Diffusion (dif-FEW-shun): Movement of molecules from an area of greater concentration to an area of lesser concentration. Agglutination (ah-glue-ti-NA-shun): Clumping of blood cells brought about by the mixing of blood types. Arteriole (ar-TEER-e-ohl): Small artery. Artery (AR-te-ree): Vessel that carries blood away from the heart. Atria (AY-tree-a): Upper chambers of the heart that receive blood from the veins.

The parasympathetic system is active primarily in normal, restful situations; the sympathetic system is most active during times of stress or when the body needs energy. the cardiovascular system The accelerator center in the medulla sends impulses along sympathetic nerves to the heart to increase heart rate and the force of contraction.
