Neutrophils

Definition

Neutrophils are a type of white blood cell that play a crucial role in the immune response by attacking bacteria and other pathogens. They are the most abundant type of white blood cells in humans and are essential for maintaining health.

5 Must Know Facts For Your Next Test

1. Neutrophils are the first responders to microbial infection, quickly migrating to sites of inflammation.
2. Nutrition influences neutrophil function, with deficiencies in vitamins A, C, E, and zinc impairing their effectiveness.
3. Chronic pulmonary illnesses like COPD can alter neutrophil activity, potentially worsening inflammation and tissue damage.
4. A diet rich in antioxidants helps maintain neutrophil function by reducing oxidative stress.
5. High levels of glucose can impair neutrophil chemotaxis and phagocytosis, emphasizing the need for proper nutritional management in diabetic patients.
