Объяснение:
Кровь состоит из эритроцитов,лейкоцитов,тромбоцитов (мелких клеток) и плазмы (жидкой части крови). Антитела и антигены в крови определяют вашу группу крови. Антитела -- это белки плазмы,которые защищают организм от чужеродных веществ в крови,таких как бактерии. Антигены -- это молекулы на поверхности эритроцитов,которые помогают продуцировать антитела. #SPJ3
