PHYSIOL 201 Lecture Notes - Lecture 17: Brainstem, Arteriole, Sinoatrial Node
Document Summary
If the flow is inadequate, the cells die. If pressure is too high, it causes too much pressure on the veins and damage tissue. The receptors are found on the arterial side and send information to the brain stem (medulla abglonada) Because the pressure drives flow and the flow to the organs have to be adequate for the organs to live. This must be maintain and is done so via the heart and pressure. If pressure gets too high, it puts a lot of strain on the vessels and cause remodeling of the vessels and can damage tissue. If the flow is too low, you don"t have enough blood going to the organs. There are 3 receptors that can sense the atrial pressure. We have receptors called arterial baroreceptors (they are found on the arterial side) that are responsible for regulating arterial pressure.
