Macrophage Function and Response

The video explains how a macrophage identifies and engulfs foreign particles. It describes the process of extending the cell membrane to surround the particle, forming a vesicle, and releasing enzymes to break down and neutralize the particle.

What action does a macrophage take when it encounters a foreign particle?

• It moves away from the particle.

• It replicates the particle.

• It engulfs the particle.

• It ignores the particle.

What happens to the foreign particle once it is inside the macrophage?

• It is immediately destroyed.

• It is used for energy.

• It is released back outside.

• It is enclosed within a vesicle.

What is the role of the vesicle formed inside the macrophage?

• To store waste products.

• To produce energy.

• To transport nutrients.

• To enclose the foreign particle.

How does the macrophage neutralize the foreign particle?

• By exposing it to sunlight.

• By releasing special enzymes.

• By freezing it.

• By dehydrating it.

What is the final step in the macrophage's process of dealing with a foreign particle?

• The particle is converted into a nutrient.

• The particle is stored for later use.

• The particle is broken down and neutralized.

• The particle is expelled from the cell.
