Deacreased vascular resistance and increased arterial pressure causes an increase in blood flow. This is important to supply organs with oxygen. 4. Restate your predictions that were correct and give data from your experiment that support them. Restate your predictions that were not correct and correct them with supporting data from your experiment. MAP would increase due to increase in activity, SVR would decrease due to decrease in resistance, CO would increase due to more force of blood being expelled. Application 1. Calcium channel blockers, a type of anti-hypertensive drug, block the entry of calcium into smooth muscle which causes smooth muscle to relax. Explain how this decreases blood pressure. This dialates arteries and arterioles and slows cardiac conduction. 2. Explain why cutting an arterial vessel will cause a greater loss of blood over the same amount of time than cutting a venous vessel. There is more force expelling blood inan arterial
