Neutrophil White Blood Cell Structure and Function | Medical Illustration #75021 (License: Personal Use)

This stylized microscopic illustration shows a human neutrophil, featuring a curved, segmented (typically 2-5 lobes) purple nucleus and numerous faint purple granules scattered in the pale pink cytoplasm. The granules contain antimicrobial enzymes and proteins critical for phagocytosis and pathogen destruction. Neutrophils are first responders to bacterial infection and inflammation.

Used in educational medical content, immunology textbooks, health websites, and clinical training materials to explain leukocyte morphology and innate immune responses; matches user intent for learning about blood cells or diagnosing infections via microscopy.
