1. Discuss which clotting factors the PT and PTT test evaluate and whether each test measures the intrinsic or the extrinsic pathways. 2. Describe the common coagulation pathway. 3. Based on Jessie’s test, which factor deficiency do you believe he has and why? 4. Jessie’s clotting factor disease is seen more often in males. Please explain why. 5. If both the PT and the PTT tests were abnormally long, which part of the coagulation pathway would be affected?

1. Question: How is ventilation different from respiration? 2. Question: Ventilation is dependent upon a pressure gradient. Describe how this pressure gradient works. 3. Question: What muscles are involved in ventilation? 4. Question: What is COPD and how does it affect ventilation? 5. Question: How does the tripod position help breathing in COPD patients?

1. Why are natural killer cells considered to be part of the innate immune response? 2. What types of cells do natural killer cells act against? 3. Describe the process whereby natural killer cells kill other cells and the role of macrophages in the process. 4. The immunologist cautioned Shanice that she may be more susceptible to virally induced cancers. Why did the immunologist state this? 5. What treatments or other options does Shanice have to counteract the natural killer cell deficienc...

1. Describe all the constituents contained in plasma and their concentrations. 2. Explain the liver’s role in production of proteins. 3. Why would albumin be important in regulating pressure at the capillaries? 4. Explain the process of fluid movement at both the arterial and venous side of the capillary. 5. What can Betty do to improve her situation?

1. Manuel is experiencing a hypersensitivity reaction. What are hypersensitivity reactions? 2. Briefly describe the different types of hypersensitivity reactions. 3. What type of hypersensitivity reaction is Manuel likely experiencing and how do you know? 4. Is this an antibody or T-cell mediated response? What class of antibodies or type of T- cells are involved? 5. Why was epinephrine administered and how does epinephrine work in this case?
