The Human Body has mechanisms to adjust or regulate blood pressure and the flow of blood. There are special sensors in the walls of the arteries and heart that feel blood pressure. Baroreceptors is the title bestowed to these special sensors. Baroreceptors sense BP & later send signals to the kidneys, the arterioles, the heart and the veins that lead them to form alterations which lower or increase BP. There are numerous techniques in which BP can be checked:

The ejection of blood will be more with each contraction if heart goes faster & contracts quickly. Both of these responses elevate the flow of blood into the arteries and raise blood pressure.

Veins accomplish 2 movements contraction and expansion. When expansion movement is done more blood get stored in the veins and the heart could not have enough amount of blood. This cause lower blood pressure as the heart pumps out less amount of blood. On the other hand, When the veins contract, less blood is stored into veins, maximum amount of blood comes back to Heart for pumping in the arteries, and, thus, the heart pumps more and more amount of blood & BP is greater.

The arterioles accomplish two movts narrowing & expansion. Resistance to the flow of blood goes down with arterioles extension & so cause low BP, similarly resistance to the flow of blood raises with arterioles shrinking and so high BP.

Decreasing or increasing amount of urine may even symbolize the changes in blood pressure. Urine is generally water that is taken out of blood so that when the kidney creates more urine, the amount (volume) of blood that fulfills the arteries and veins reduces, & it dimishes BP.
