Question

what are the three stages of hemostasis?
vasodilation, platelet aggregation, and inflammation.
apoptosis, mitosis, and necrosis.
erythropoiesis, leukocytosis, and thrombocytosis.
vasoconstriction, platelet plug formation, and coagulation.
dehydration, hypovolemia, and hypernatremia.

Explanation:

Hemostasis is the process to stop bleeding. Vasoconstriction narrows blood vessels to reduce blood flow. Platelet plug formation is when platelets aggregate at the injury site. Coagulation involves clotting factors forming a fibrin clot. Vasodilation (widening vessels) is not part of hemostasis. Apoptosis (cell death), mitosis (cell division), necrosis (cell death), erythropoiesis (red - blood - cell formation), leukocytosis (high white - blood - cell count), thrombocytosis (high platelet count), dehydration (low water), hypovolemia (low blood volume), and hypernatremia (high sodium) are not the three stages of hemostasis.

Answer:

Vasoconstriction, platelet plug formation, and coagulation.
