Final answer:
The umbilical cord connects the fetus to the placenta, where it facilitates the exchange of oxygen, nutrients, and waste between the mother and the fetus.
Step-by-step explanation:
The umbilical cord connects the fetus to the placenta, not to the Fallopian tubes, cervix, or ovum. The umbilical cord is a critical lifeline, containing two arteries and one vein. The two umbilical arteries carry oxygen-depleted blood and waste products from the fetus to the placenta. From there, these wastes are transferred to the mother's circulatory system for disposal. Conversely, the single umbilical vein carries oxygen-rich and nutrient-laden blood from the placenta back to the fetus. This exchange is vital for the growing fetus to receive the necessary elements for development while also removing waste products
