_______ are Cells That Ingest Bacteria and Other Foreign Matter

Question

_______ are cells that ingest bacteria and other foreign matter.
A) Lymphocytes
B) Natural killer cells
C) Phagocytes
D) Erythrocytes

Accepted Answer

Phagocytes are cells capable of ingesting and absorbing bacteria, particles, and other foreign matter. Examples of phagocytes include macrophages, neutrophils, and dendritic cells. Lymphocytes and natural killer cells are involved in immune responses but do not directly ingest foreign matter. Erythrocytes, also known as red blood cells, do not have the capacity to ingest foreign matter as they do not have a nucleus or the organelles necessary for phagocytosis.
