Original caption

A neutrophil stretches its arms and hunts through red blood cells in incredible 1950s microscope footage captured by David Rogers at Vanderbilt University. The white blood cell chases Staphylococcus bacteria using chemical signals before engulfing them through phagocytosis. Billions of these first-responder cells are constantly on patrol, ready to squeeze through tissue and destroy invaders the moment they appear. They work around the clock without you noticing, helping keep your body healthy every day. #health #blood #cell #loneliness
