Macrófagos são células do sistema imunológico que desempenham um grande papel na defesa do organismo. Originados a partir de monócitos no sangue, eles se movem para os tecidos onde fagocitam patógenos, células mortas e outros detritos. Além disso, macrófagos ajudam a iniciar a resposta imune adaptativa apresentando antígenos aos linfócitos T e secretando citocinas que modulam a atividade de outras células imunes. #biologia #enem #vocesabia #curiosidades #vestibular

Macrófagos e neutrófilos são glóbulos brancos que fazem parte do sistema imunológico inato. Os macrófagos patrulham os tecidos, engolindo e digerindo patógenos, células mortas e detritos celulares, atuando como a primeira linha de defesa. Os neutrófilos também respondem rapidamente às infecções para destruir os patógenos. Ambos são essenciais para a resposta imune do corpo.
