Phagocyte, type of cell that has the ability to ingest, and sometimes digest, foreign particles, such as bacteria, carbon, dust, or dye. … In the blood, two types of white blood cells, neutrophilic leukocytes (microphages) and monocytes (macrophages), are phagocytic.

Can phagocytes kill viruses?

Another function of phagocytosis in the immune system is to ingest and destroy pathogens (like viruses and bacteria) and infected cells. By destroying the infected cells, the immune system limits how quickly the infection can spread and multiply.

What are the two main types of phagocytes?

Types of phagocytes In humans, and in vertebrates generally, the most-effective phagocytic cells are two kinds of white blood cells: the macrophages (large phagocytic cells) and the neutrophils (a type of granulocyte).

Which white blood cells are the most active phagocytes?

Are B cells white blood cells?

The B-cell, also called B-lymphocyte, is a type of white blood cell that plays a significant role in protecting your body from infection.

How do phagocytes fight infection?

Phagocytes surround any pathogens in the blood and engulf them. They are attracted to pathogens and bind to them. The phagocytes membrane surrounds the pathogen and enzymes found inside the cell break down the pathogen in order to destroy it.

What are the types of white blood cells?

White blood cells are part of the body’s immune system. They help the body fight infection and other diseases. Types of white blood cells are granulocytes (neutrophils, eosinophils, and basophils), monocytes, and lymphocytes (T cells and B cells).

What are phagocytic white blood cells?
