Question

Criteria for Success: To be successful you will make sure you complete diagrams as instructed in the tasks, including proper values on the x & y-axis as well as labeling those. You also need to make sure to list or provide explanation where necessary or where it is asked in the tasks. A successful submission would be very clear and easy to read and it would be easy to see the differences in pressures and volumes based on the given situations. For submission, you can submit them as a pdf or image from a phone if you are drawing these at home. I also suggest looking at the homework you have completed and the provided examples to help you in completing these tasks.

Case Studies Tasks:

1. John recently visited the Doctor and was informed he has a blood pressure of 165/110 mmHG. Diagram a graph for pressure vs volume. The graph should contain a normal pressure to volume graph in a healthy heart and also a pressure vs. volume graph for John's hypertension. List 3 factors that could contribute to his hypertension.
2. Revisiting Jane: Jane was riding her horse on a warm sunny day (101 degrees Fahrenheit) when suddenly her horse stopped and reared up in the air. Jane was not prepared for this and fell hard backwards into the ground. As she hit the ground Jane's leg was gashed open by a large, sharp boulder that she fell next to. Jane began to bleed severely. Jane's pulse seems to be low and her respiratory rate is at 25 bpm. Jane's body spends the next couple hours physiologically compensating for her blood loss. Based on your knowledge of the cardiovascular system complete the following: Make a graph of Jane's cardiac output/venous return (y-axis) vs (as a function of) her central venous pressure. Provide two points on the curve that represent (A) before she fell off the horse and (B) after she fell and suffered significant bleeding. Make sure the pressures and L/min are labeled correctly one each axis. Then list any compensatory mechanisms the body is using to return the cardiac output to normal while bleeding.
3. Sarah was recently diagnosed with an obstructive lung disorder. In their diagnostic process the doctors completed a Forced Vital Capacity test on Sarah to determine her lung function. Based on this, (A) diagram a Vital Capacity test with lung volumes for a healthy individual and on the same graph include the VC test with lung volumes for Sarah's diagnosis. The doctors also found that Sarah's oxygen saturation was at 87%. Therefore, (B) diagram an oxygen saturation curve graph that shows a normal oxygen saturation curve and a curve representing Sarah's condition.

Criteria Ratings Pts This criterion is linked to a Learning OutcomeScientific Inquiry 5.0 pts Student demonstrates the ability to investigate case study and answer all of the questions given. 4.0 pts Student demonstrates the ability to investigate case study and answers majority of the questions given. 3.0 pts Student demonstrates the ability to investigate the case study, but is only able to answer half of the questions. 1.0 pts Student demonstrates the ability to investigate the case study, but is only able to answer less than half of the questions. 0.0 pts Student does not demonstrate ability to extract material from the case study.Student did not submit the assignment/complete the module. 5.0 pts This criterion is linked to a Learning OutcomeMastery of the Content 55.0 pts Student demonstrates an understanding of the content by providing an accurate and in depth explanation of the physiological processes and adjustments in relation to the case study. 44.0 pts Student demonstrates an understanding of the content accurate and in depth explanation of the physiological processes and adjustments in relation to the case study. Student may be missing one or two key actions, but overall has a above average understanding of the processes. 33.0 pts Student demonstrates some understanding of the content. Student has a foundational understanding of the physiological system, but struggles to relate the actions and physiological processes together to explain the case study. Missing more than 2 key points. 11.0 pts Student demonstrates an incomplete understanding of the content. Student is unable to identify key physiological processes and organs in relation to the clinical case. 0.0 pts Student demonstrates no understanding of the content. Student either has no knowledge of the concepts displayed in their answer or chose not to answer. 55.0 pts Total Points: 60.0

Answer 1

The jhons condition is hypertensionwhich meanssystolic and diastolic pressure higher than the normal level 120/80.Here different factors may affect the blood pressure .They are listed below

life style

genitic disorders

Life style means badfood habbits lie over eating,junk food,unhealthy habit like alcohol consumption,smoking etc.some genitic disorders may affect the blood pressure.

    In the case jane the blood loos may leads to the low cardiac out put .this is the one of the compesatory mechanism to prevent more loss of blood.Other mechanism chemoreceptor reflex,renal reabsorption of sodium and water,reabsorption of tissue fluid
