1 UNIT 6: CARDIOVASCULAR SYSTEM 1) List the three general functions of BLOOD. REVIEW QUESTIONS Blood 2) a) What are the three formed elements /cellular elements in blood? b) Describe the composition of the liquid portion of blood, PLASMA. c) What is the name of RBC (erythrocyte) formation? Where do blood cells form? d) Erythropoietin is available as a drug (sold by Amgen!). Why would athletes abuse it? 3) Across what type of blood vessel are nutrients and gases exchanged between mother and fetus at the placenta? 4) Approximately how long does a RBC live? Where are they recycled? 5) What is the function of blood platelets?

2 6) a) Distinguish between a THROMBUS and an EMBOLUS. b) When a blood clot forms in a vessel supplying the heart and heart tissue dies, the result is a. c) When a blood clot forms in a vessel supplying the brain and brain tissue dies, the result is a. 7) What happens when there is a mismatched blood transfusion. 8) a) Which blood type is the universal recipient? Why? b) Which blood type is the universal donor? Why? c) How might a technique to remove A and B antigens from red blood cells be used to increase the supply of donated blood? d) Discuss Rh antigens and antibodies. Also, explain how the Rh factor affects moms and babies. e) Why can a person receive platelets donated by anyone, but must receive a particular type of whole blood? 9) Starting with hemostasis, describe the process for how a blood clot forms. Include the activation of fibrinogen in your explanation. 10) Describe the following blood conditions: a) hemophilia: b) anemia: c) leukemia: 11) What is polycythemia and when does it occur naturally?
