41% to 50%

Female Hematocrit range

36 to 48%

Bleeding Time

Duration it takes to stop bleeding

Vascular Spasm

Smooth muscle in vessel go through vasoconstriction (contracts in muscle)

Coagulation time

Time it takes for blood to clot

Coagulation cascade

Series of chemical reaction to make clot

Coagulation cascade order

Prothrombin → thrombin → fibrinogen → fibrin

Anemia

Reduced oxygen carrying in blood, low RBC or failure

Polycythemia

RBC count exceed normal limit

Hemocytometer

Device in lab to count and calculate concerntration of cells in a given volume of fluid
