The video explores the fetal environment, focusing on how nutrients are delivered and waste is managed. It explains that fetuses urinate in the womb, drinking amniotic fluid, which is sterile. Waste products are filtered through the umbilical cord to the mother. Fetal digestion involves the formation of meconium, a sterile mass, due to the absence of bacteria in the large intestine.
