Script: Zarnas uzsāk darbību jau no 12 nedēļu vecuma un tas turpinās 6 nedēļas.

Materiālu, kas sākotnēji izdalās no augļa un jaundzimušā resnās zarnas, sauc par mekoniju. Tā sastāvā ir gremošanas enzīmi, olbaltumvielas un mirušas šūnas, ko izdalījis gremošanas kanāls.

All ages referenced to fertilization, not last menstrual period. One month = 4 weeks.
