Question

Fill in the blanks.

__________ are the cells which ingest pathogens which invade our body.

Answer 1

Pathogens:

1. Harmful microorganisms which cause diseases are called pathogens.
2. Most pathogens are present in our surroundings, so we are susceptible to many diseases.
3. However, our body also has some built-in defense mechanisms to protect us from those invading pathogens.
4. If the pathogens overcome all our physical barriers and enter the body, phagocytes come into play.
5. They are the cells that ingest invading pathogens.
6. Neutrophils and macrophages are the two types of WBCs that carry out phagocytosis.

Hence, phagocytes are the cells that ingest pathogens that invade our body.
