1. Jane was riding her horse on a warm sunny day (101 degreesFahrenheit) when suddenly her horse stopped and reared up in theair. Jane was not prepared for this and fell hard backwards intothe ground. As she hit the ground Jane's leg was gashed open by alarge, sharp boulder that she fell next to. Jane began to bleedseverely. Jane's pulse seems to be low and her respiratory rate isat 25 bpm. Jane's body spends the next couple hours physiologicallycompensating for her blood loss. Based on your knowledge of thecardiovascular system complete the following: Make a graph ofJane's cardiac output/venous return (y-axis) vs (as a function of)her central venous pressure. Provide two points on the curve thatrepresent (A) before she fell off the horse and (B) after she felland suffered significant bleeding. Make sure the pressures andL/min are labeled correctly one each axis. Then list anycompensatory mechanisms the body is using to return the cardiacoutput to normal while bleeding.
2. Sarah was recently diagnosed with anobstructive lung disorder. In their diagnostic process the doctorscompleted a Forced Vital Capacity test on Sarah to determine herlung function. Based on this, (A) diagram a Vital Capacity testwith lung volumes for a healthy individual and on the same graphinclude the VC test with lung volumes for Sarah's diagnosis. Thedoctors also found that Sarah's oxygen saturation was at 87%.Therefore, (B) diagram an oxygen saturation curve graph that showsa normal oxygen saturation curve and a curve representing Sarah'scondition.
