Homeostasis in Blood Pressure Using Feedback Loops
Transcript of Homeostasis in Blood Pressure Using Feedback Loops
down and gravity keeps the blood
low. Receptor The heart, aorta (artery leaving the heart), internal carotid artery (artery taking blood to the brain) have sensors which detect changes in blood pressure. Integrating Center The brain stem (the bottom part of the brain that controls body functions like breathing and heart beat) gets the information that the blood pressure is too high. Effector The heart slows down and the blood vessels relax to let more blood through, this lowers the blood pressure. Response The blood pressure adjusts and
is normalized. If the feedback loop failed, the blood pressure would not be adjusted and the animal would be at risk for a heart attack, stroke, or kidney failure.
