Expert Solution & Answer

Summary Introduction

Introduction:

A phagocyte is a type of cell present within the body which is capable of “engulfing and destroy bacteria” and other “small cells and particles”.

Answer to Problem 1MC

Correct answer:

The phagocytes of the epidermis are known as dendritic cells. Therefore, option (d) is correct.

Option (d) is given as “dendritic cell”.

Explanation of Solution

Justify reason for the correct statement:

Dendritic cells are phagocytes that are present in the epidermis of the skin. They kill microbes non-specifically. The dendritic cells phagocyte the foreign body and break it by the phagolysosome formation.

Hence, option (d) is correct.

Justify reasons for the incorrect statements:

Option (a) is given as “microglia”

Microglia is located in the brain and spinal cord and they are macrophages cells. Hence it is a wrong answer.

Option (b) is given as “goblet cells”.

The goblet cells are epithelial cells which secrete mucin. These cells are usually found in the epithelial lining of the “respiratory and the intestinal tracts”. These cells are not “macrophages or phagocytes”. They are not present in the epidermis. Hence, it is a wrong answer.

Option (c) is given as “alveolar macrophages”

Alveolar macrophages are present in the lungs. Their main function is to remove the dust particles in the lungs due to inhalation. Hence, it is a wrong answer.

Hence, options (a), (b), and (c) are incorrect.

Conclusion

The phagocytes of the epidermis are known as dendritic cells, not the alveolar macrophages, microglia, and goblet cells.
