PHYSIOL 201 Lecture Notes - Lecture 18: Capillary Pressure, Muscle Tone, Hemostasis
Document Summary
Since map and co went up but tpr went down, it tells you that co changed more than tpr. Hr and sv went up which is why the co also went up. Because tpr went down, it means vasodilation which increases flow to the organs and tissue that are involved in the exercise. So skeletal muscle and the skin get the most increase in flow. The skin gets more flow because as you increase blood flow, you increase heat dissipation. So the heat by convection, as the blood flows through the skin which is warmer, as the wind blows across the heat is dissipated to the environment. You see a decrease in the abdominal and kidney blood flow. This is due to maintaining the high blood flow to the skin and skeletal muscle. When map changes, you normally get a baroreceptor feedback.
