Question

In WBC, we have cells which move like amoeba and attack foreign materials and engulf them. These are called scavengers. Name these cells.
A) Lymphocytes
B) Monocytes
C) Esinophills
D) Basinophylls

Answer 1

Monocytes are called as Natural Scavengers, as they attack and engulf any foreign body.

Explanation:

• WBCs or white blood cells or Leukocytes as we call them are a very distinct and important group of cells involved in protection of our body from any any pathogenic activity.

• There are primarily two types of Leukocytes, Granulocyte and Agranulocyte. Neutrophils ,Eosinophils and Basophils are different types of Granulocytes. Monocytes and Lymphocytes are different types of Agranulocyte.
• According to the following given options,

1. Lymphocytes : They produce B and T types of cells that are primarily involved in building of immune system.
2. Monocytes : Monocytes along with Neutrophils are phagocytic in nature and capture and destroy any foreign body by engulfing them. Hence, they come to be called as scavengers.
3. Eosinophils : They are related with allergic and inflamatory reactions about how to reduce them.
4. Basophils : Basophils are responsible for secreting Heparin and Histamine, basically all those chemicals that reduce allergic reaction.

Answer 2

The answer is B) Monocytes.

Lymphocytes, Monocytes, Eosinophils, and Basophils are all white blood cells.

Monocytes are a type of white blood cell that are phagocytic in nature. Due to their phagocytic nature, they move to possible infection sites and attack the pathogen or feed on the remnants of the destroyed pathogens.

Lymphocytes are white blood cells that participate in the immune response of the body. They are of two types; B lymphocytes and T lymphocytes. These help in carrying out the cell-mediated immune response and the antibody-mediated immune responses in the body.

Eosinophils are white blood cells that can be stained by the eosin stain. They help in producing antihistamine, which usually helps in controlling allergic reactions.

Basophils are white blood cells that release histamine and heparin. Histamine is usually associated with allergic responses and inflammation. Heparin is an anticoagulant present in the blood.
