Describe some of the effects that expanded blood vessels will have on blood pressure. What effect will an increased heart rate have on blood pressure? What effect will a decreased heart rate have on blood pressure? What relationship will water volume have on blood pressure? What relationship will blood volume have on blood pressure? Be sure to look up the meaning of proximal and distal (this is not included in the lesson) Lesson 4.01 Honors: Blood Vessels & Electrocardiograms Be able to identify the following on a diagram………. o Atrial Depolarization o Atrial Repolarization o Ventricular Depolarization o Ventricular Repolarization Be able to explain what is measured by each of the following……… o P Wave o T Wave o QRS Complex Which layer(s) do all blood vessels have in common? Describe the structure and function of capillaries. What role does smooth muscle play in blood vessels, and where is it located? Which type of blood vessel is the thickest? Which type of blood vessel has the greatest amount of blood pressure? What allows arteries to increase in size as they become filled with blood? What role do valves play in blood flow? Name and briefly describe the three main layers of blood vessels What tissues are likely to be found in arteries? What tissues are likely to be found in veins? What mechanisms ensure that blood continuously flows throughout our body? 1 Lesson 4.02: Components of Blood What causes hemophilia and what effect does it have in the clotting process? Identify some symptoms of anemia? What causes white blood cell counts to increase and decrease? What causes red blood cell counts to increase and decrease? What can occur if there is an abnormally high amount of platelets in the body? If a person is anemic, which type of blood cell is likely to be found in smaller quantities? What role will hemoglobin play in anemia? Is anemia a disease that can be inherited? Why or why not? What are some symptoms associated with Cooley’s anemia? How would a reduction in platelets affect bleeding? What are some causes of a stroke? What is likely to happen if your white blood cell count is below normal? What is likely to happen if your red blood cell count is below normal? What can be inherited through erythroblastic anemia? How would the appearance of red blood cells differ in a person that has anemia? How will amounts of oxygen be affected in a person that has anemia? What symptoms are likely to occur in a person with beta-thalassemia? Can anemia be treated with a blood transfusion? Explain Can all types of anemia be treated with excessive iron supplements? Explain Lesson 4.03: Hemostasis, Typing, and Transfusion What makes Type O blood different than A, B, and AB? How are you able to tell if antibodies are found in blood plasma? Be able to determine which blood types can and cannot be donated and received………. o A o B o AB o O What role do antigens play in our blood? What role do antibodies play in our blood? Identify the correct steps of blood clotting after a cut occurs. 2 What role does a platelet plug play in the clotting process? What role does a vascular spasm play in the clotting process? What role does fibrin play in the clotting process? 3
