Notes from NEET topper
Types of White Blood Cells (WBCs):
There are several types of white blood cells, each with specific functions in immune response:
-
Neutrophils: Neutrophils are the most abundant type of WBCs and are rapid responders to infections. They engulf and destroy bacteria and other foreign invaders.
-
Lymphocytes: Lymphocytes are responsible for specific immune responses and antibody production. They include B cells, which produce antibodies, and T cells, which directly attack infected cells.
-
Monocytes: Monocytes are large, phagocytic cells that ingest and break down pathogens. They can also transform into tissue macrophages, which play a role in tissue repair and immune regulation.
-
Eosinophils: Eosinophils primarily combat parasitic infections and play a role in allergies and asthma. They release enzymes that neutralize parasites and help modulate immune responses.
-
Basophils: Basophils are involved in inflammatory responses and allergic reactions. They release histamines, which contribute to inflammation and vasodilation.
