To effectively understand white blood cell (WBC) functions, focus on their roles in the immune response. WBCs, including neutrophils, lymphocytes, monocytes, eosinophils, and basophils, protect the body against infections and foreign invaders. Neutrophils act quickly during bacterial infections, often supported by antibiotics like ceftriaxone injection, which helps eliminate pathogens. Lymphocytes manage immune memory and antibody production. Monocytes digest pathogens and signal other immune cells. Eosinophils and basophils respond to allergens and parasites. Studying lab reports, observing WBC count variations during infections, and understanding how medications like
ceftriaxone injection impact immune response are key to mastering WBC functions.
