How do basophils respond to tissue damage? (Module 17.9B)

Basophils enter damaged tissue and release a variety of chemicals, including histamine, which promotes inflammation.

The intrinsic pathway of coagulation is activated by the

activation of proenzymes exposed to collagen.

Most of the iron that is removed from degraded hemoglobin is

recycled to red bone marrow.

All the circulating red blood cells originate in the

red bone marrow.

Granulocytes form in

red bone marrow.

Define hemocytoblasts. (Module 17.3A)

Hemocytoblasts form from hematopoietic stem cells and divide into lymphoid stem cells and myeloid stem cells.

________ transport(s) oxygen and CO2 in the RBCs.

Hemoglobin molecules
