Which of the following would result in more rather than less clotting? Check all that apply. The correct answers reflect the effect of hyperglycemia on the clotting pathway! less conversion of plasminogen to plasmin 7 000000000 abnormally low number of platelets platelets more sensitive to thromboxane A2 elevated conversion of plasminogen to plasmin platelets less sensitive to thromboxane A2 low sensitivity to NO and PGI2 increased prothrombin in the blood increased amount of fibrinogen in the blood less prothrombin in the blood abnormally high number of platelets less fibrinogen in the blood high sensitivity to NO and PGI2
Fill in the blanks with the appropriate word from the following group: hemolysis, water, increase, crenation, decrease, isotonic. The RBC’s in Figure 8.7 “a” are suspended in an (blank1) solution. If red blood cells are placed in a hypertonic solution they lose (blank2) and (blank3) in size. This process is called (blank4). If red blood cells are placed in a hypotonic solution they gain (blank5), (blank6) in size, and may burst. This process is called (blank7).
