This activity asks that you place the steps of phagocytosis in the correct order. drag the steps below into the boxes provided to indicate the order in which they occur.

Activation of the Phagocyte

Chemotaxis of Phagocytes

Attachment of the Phagocyte to the Microbe or Cell

Ingestion of the Microbe or Cell by the Phagocyte

Destruction of the Microbe or Cell

Explanation:

. Phagocytosis is the primary method used by the body to remove free microorganisms in the blood and tissue fluids.Phagocytic cells include neutrophils, eosinophils, monocytes, macrophages, dendritic cells, and B-lymphocytes. The process of phagocytosis often happens when the cell is trying to destroy something, like a virus or an infected cell, and is often used by immune system cells.Process of phagocytosis is

1.Chemotaxis which is defined as the movement in response to chemical stimulation.

2.Adherence: attachment to a microbe.

3.Ingestion: engulfing pathogen with pseudopodia wrapping around pathogen.

4.Digestion: phagosome maturation.

5.Elimination: phagocytes eliminate remaining pieces of microbe via exocytosis.

There are four main steps in phagocytosis

1. the plasma membrane entraps the food particle

2. a vacuole forms within the cell to contain the food particle

3. lysosomes fuse with the food vacuole

4. enzymes of the lysosomes digest the food particle.

during the process of dna replication, brdu can replace thymidine and incorporate into the newly synthesized dna, cell proliferation thus can be reflected in the extent of brdu incorporation.
