1. What are the two mechanisms of hemolysis that occur during a transfusion
reaction?
Hemolytic anemia and aplastic anemia
Complement activation and erythropoiesis
Intravascular hemolysis and extravascular hemolysis
Phagocytosis and coagulation
2. Describe how afterload influences cardiac function.
Afterload is solely determined by heart rate.
Afterload is the volume of blood in the ventricles before contraction.
Afterload affects the heart by determining the amount of resistance
the ventricles must overcome to eject blood.
Afterload has no effect on cardiac function.

The inflammation of lung tissue.
The overexpansion of the alveoli in the lungs.
The accumulation of fluid in the alveoli.

structure of the hemoglobin?
Tertiary structure
Primary structure
Secondary structure
Quaternary structure
