Anatomska terminologija

Enterociti ili intestinalne apsorpcijske ćelije (crijevne apsorpcijske ćelije), su jednoslojne cilindrične epitelne ćelije koje oblažu unutrašnju površinu tankog i debelog creva. Glikokaliksni površinski sloj sadrži perobavne enzime. Mikrovili na apikalnoj površini povećavaju njegovu površinu. Ovo olakšava transport brojnih malih molekula u enterocite iz intestinalnog lumena. To uključuje razgrađene proteine, masti i šećere, kao i vodu, elektrolite, vitamine i žućne soli. Enterociti također imaju endokrinu ulogu: luče hormonee kao što je leptin.
