SEGS, also known as "segs", "PMNs" or "polys" (polymorphonuclears), refers to neutrophils, which are a type of white blood cell. These cells are the body's primary defense against bacterial infections and physiological stress.
Neutrophils Explained
Here's a breakdown of what you need to know about neutrophils (SEGS):
-
Role: Neutrophils are critical for immune defense. They identify and destroy harmful bacteria and help the body manage stress.
-
Maturity: Mature neutrophils have a segmented nucleus. This characteristic appearance leads to the name "segs."
-
Other Names: Besides SEGS, these cells are also called:
- PMNs (polymorphonuclear leukocytes)
- Polys
-
Function: Neutrophils act as the first responders to infection. They engulf and digest bacteria, a process called phagocytosis.
