How does a foetus excrete waste?
The fetus can excrete urine into the amniotic fluid but there is very little waste in it. The mother’s body works to attend to the other exchanges. Because babies are not eating, there is no waste as we know it. Unborn babies in distress may pass meconium, a dark sticky substance which lines the bowel, and is usually passed in the first days after the birth but is different to feces.
