1. Defining Neutrophils Absolute: A Deep Dive
Neutrophils absolute refers to the actual number of neutrophils present in a microliter of blood. Neutrophils, a type of white blood cell (leukocyte), are essential components of the immune system. They act as the first line of defense against bacterial and fungal infections. To truly grasp “what is neutrophils absolute,” it’s imperative to delve into the multifaceted nature of these cells and their significance in overall health.
1.1 Neutrophils: The Body’s First Responders
Neutrophils are produced in the bone marrow and released into the bloodstream. Their primary function is to identify and destroy harmful invaders, such as bacteria, fungi, and viruses. They accomplish this through a process called phagocytosis, where they engulf and digest the foreign particles.
