what is true about thrombin? it converts fibrinogen into fibrin. it activates the extrinsic pathway of coagulation. it activates the intrinsic pathway of coagulation. it causes platelet aggregation to the site of a wound. question 22 (1 point) what is false about monocytes? they differentiate into macrophages. they arise from lymphoid stem cells in the bone marrow. they are agranular. they are larger than erythrocytes.

Answer

Brief Explanations:

Thrombin is an enzyme in the blood - clotting process that converts fibrinogen into fibrin. Monocytes are white blood cells that differentiate into macrophages, are agranular, and larger than erythrocytes. They arise from myeloid, not lymphoid, stem cells in the bone marrow.

Answer:

Question 21: It converts fibrinogen into fibrin. Question 22: They arise from lymphoid stem cells in the bone marrow.
