during Mental Stress‚ Following Isometric Exercise and after Occlusion ------------------------------------------------- 1. Introduction A common technique in measuring blood flow in the human forearm is by venous occlusion plethysmography. The fundamental principle is that if the venous return from the arm is blocked‚ the forearm will swell at a rate relative to the rate of the arterial inflow (Whitney‚ 1953). However‚ the rate of increase in volume of the forearm and its relationship with the

How things flow through the heart: • blood drains into the right atrium through the superior vena cava‚ inferior vena cava‚ and the coronary sinus (drains the heart muscle itself)→Right Ventricle→pulmonary semilunar valves→lungs→pulmonary veins→left atrium→bicuspid valve→left ventricle→aortic semilunar valve→systemic circuit. What the valves do: • Prevent backflow into the atria and ventricles‚ ensuring that blood only flows one way through the heart. what vessels bring blood to the heart and
