Chapter 22, Problem 1DYKB

_____ 1. All of the following are phagocytic cells except

a. neutrophils.
b. T-lymphocytes.
c. macrophages.
d. eosinophils.

Expert Solution & Answer

Summary Introduction

Introduction:

The phagocytosis is the process in which the cells eliminate the pathogens by engulfing them. The substances which are engulfed by the cell may be infectious agents, cellular debris. This is a very common process for food intake in amoebas.

Answer to Problem 1DYKB

Correct answer:

The T-lymphocytes secrete cytokines and activate other cytotoxic T-lymphocytes to invade the pathogens. Therefore, option b. is correct.

Explanation of Solution

Reason for the correct statement:

Option b. is given as “T-lymphocytes”. The T-lymphocytes are the cells which provide protection against the antigens by releasing cytokines and also activate the cytotoxic cells which further release other cytokines. The infectious antigens are eliminated by the cytokines, not by phagocytosis process. Hence, the T-lymphocytes are not the phagocytic cells.

Hence, option b. is correct.

Reasons for incorrect statements:

Option a. is given as “neutrophils”. The neutrophils’ function is to destroy infectious agents through a process known as phagocytosis. It is the process in which the infectious agent is engulfed by the neutrophils. Neutrophils are phagocytic cells. Hence, option a. is incorrect.

Option c. is given as “macrophages”. The macrophages also involve the phagocytosis process in which the engulfed infectious agent is covered to form phagosome and interact with lysosomes to release a residue in the external environment. Macrophages are phagocytic cells. Hence, option c. is incorrect.

Option d. is given as “eosinophils”. Eosinophils also participate in the immune response associated with allergy and asthma and are involved in phagocytosis of antigen-antibody complexes. Eosinophils are phagocytic cells. Hence, option d. is incorrect.

Hence, options a., c., and d. are incorrect.

Conclusion

The neutrophils, macrophages, and eosinophils all are phagocytic cells because they show phagocytosis, but T-lymphocytes releases cytokines to eliminate pathogens.
