I know this has something to do with the cardiovascular center and the systemic stimulation of the Heart with the cardiac accerlator nerves
Thebigquickie,
The subject is quite technical, I shall try to simplify it here. The body's homeostatically cultivated systems are maintained by negative feedback mechanisms, sometimes called negative feedback loops. In negative feedback, any change or deviation from the normal range of function is opposed, or resisted. The change or deviation in the controlled value initiates responses that bring the function of the organ or structure back to within the normal range. Negative feedback loops require a receptor, a control centre, and an effector. A receptor is the structure that monitors internal conditions. The Human body has receptors in the Blood vessels that monitor the pH of the blood. The blood vessels contain receptors that measure the resistance of blood flow against the vessel walls, thus monitoring Blood pressure. Receptors sense changes in function and initiate the body's homeostatic response. These receptors are connected to a control centre that integrates the information fed to it by the receptors. In most homeostatic mechanisms, the control centre is the Brain. When the brain receives information about a change or deviation in the body's internal conditions, it sends out signals along nerves. These signals prompt the changes in function that correct the deviation and bring the internal conditions back to the normal range.
