Answer: A. Umbilical CordExplanation:
The structure connecting the foetus to the placenta is the umbilical cord. The umbilical cord is a vital part of the development of a foetus, as it is responsible for providing the necessary nutrients and oxygen, as well as removing waste products. Here's a breakdown of its functions and features:
  • Function: The umbilical cord connects the developing foetus to the placenta, which is an organ that develops in the uterus during pregnancy. The placenta provides nutrients and oxygen to the foetus and removes waste products.
  • Composition: The umbilical cord is made up of two arteries and one vein, surrounded by a gelatinous substance called Wharton's jelly. The vein carries oxygen-rich blood and nutrients from the placenta to the foetus, while the two arteries carry oxygen-poor blood and waste products from the foetus back to the placenta.
  • Length: The umbilical cord is typically around 50-60 cm (20-24 inches) long, allowing the baby to move and grow comfortably within the womb without putting too much strain on the cord.
  • Role in delivery: After the baby is born, the umbilical cord is cut and clamped, separating the baby from the placenta. The remaining stump on the baby's abdomen eventually dries up and falls off, leaving behind the belly button.
It is important to note that other structures, such as the amnion, yolk sac, and chorion, all play crucial roles in the development and protection of the foetus, but they are not directly responsible for connecting the foetus to the placenta.
