Lymphocytes

Definition

Lymphocytes are a type of white blood cell essential for the body's immune response. They play a critical role in identifying and neutralizing pathogens, including viruses and bacteria.

5 Must Know Facts For Your Next Test

1. Lymphocytes can be divided into B cells, T cells, and natural killer (NK) cells, each with specific functions in the immune response.
2. B cells produce antibodies that help neutralize pathogens, while T cells directly attack infected or cancerous cells.
3. Nutrition can influence lymphocyte function; deficiencies in certain nutrients like vitamins A, C, D, and E can impair their activity.
4. A diet rich in antioxidants found in fruits and vegetables supports lymphocyte health by reducing oxidative stress.
5. Omega-3 fatty acids have anti-inflammatory properties that can modulate lymphocyte function beneficially for pulmonary health.
