How many types of White Blood cells?

Types of white blood cells

There are two main types of leukocytes, or white blood cells:

1. Phagocytes

These cells surround and absorb pathogens and break them down, effectively eating them.

There are several types:

• Neutrophils

• Macrophages

• Dendritic cells

• Monocytes

• Mast cells

2. Lymphocytes

• Lymphocytes help the body remember previous invaders and recognize them if they return to attack again.

• Lymphocytes begin their life in Bone marrow.

• Some stay in the marrow and develop into B lymphocytes (B cells); others travel to the thymus and become T lymphocytes (T cells). These two cell types have different roles.
