liver to be cleared? ✔✔haptoglobin
What is the name of the process by which phagocytic cells are attracted toward a substance such as a
bacterial peptide? ✔✔chemotaxis
The principal type of leukocyte in the process of phagocytosis is the ✔✔monocyte
Cells that can act as antigen processing cells (APCs) for exogenous antigens include
✔✔macrophages/monocytes and dendritic cells
