Explain the physiologic processes involved in homeostatic regulation of temperature, pulse, respirations, and blood pressure
What will be an ideal response?
Answer:
Temperature: is maintained at a constant range by the thermoregulatory set point of the thermoregulatory center in the hypothalamus. Receives messages from cold and warm thermal receptors located throughout the body, compares the information with the set point and initiates responses either to produce or conserve body heat or increase heat loss. (Heat primary source of metabolism) (normal 96.7-100.5)
Pulse: is regulated by the autonomic nervous system through the sinoatrial (SA) node of the heart. (pulse rate is the number of the pulsations felt over a peripheral artery or heard over the apex of the heart in 1 minute) (normal 60-100 beats/min)
Respiration: the rate and depth of breathing can change is response to tissue demands. The changes are brought by the inhibition or stimulation of the respiratory muscles by the respiratory centers in the brain. Activation of the respiratory center occurs via impulses from chemoreceptors located in the aortic chart and carotid arteries, via stretch and irritant receptors in the lungs and via receptors in muscles and joints (cerebral cortex allows for voluntary control of breathing) (normal 12-20)
Blood Pressure: stroke volume and heart rate determines cardiac output. Cardiac output and peripheral resistance determines blood pressure
