Analysis Using the data from Table 17-1, create a bar graph comparing mean pulse pressures for the lying and standing body positions. Calculate and include standard error bars on your graph. (See the lab folder statistics on blackboard for links to an explanation if you have not done that before) Extra credit: perform a paired t-test to see if any differences between mean pulse pressures are significant. (See blackboard lab folderstatistics for instructions) Application questions Answer the following application questions in complete sentences. Be sure to type the above your answer. If you are turning in these questions as an informal lab report, append your data que table and graph to the typed questions/answers. Be sure to include a complete header on your lab report. 1 was your hypothesis supported, or refuted by your experimental results? Support your conclusion with your results. 2. When you stand up from a supine position, there is a shift of blood (500-700ml from the veins of the thorax to the veins of the lower extremity. This pooling of blood causes a drop in venous return to the hear (preload) which causes a transient decrease in blood pressure. Were you able to measure this effect in your experiment? if so, explain the mechanism used by your cardiovascular system to return a decreased BP back to normal. This adjustment usually occurs within a few cardiac cycles-which is amazing! b If not, explain your findings-ie why didn’t the blood pressure drop even though blood was pooling the lower extremities? (hint think bloodpressure homeostasis mechanism)
