How does the fetus get nutrition from the mother?
The fetus is connected by the umbilical cord to the placenta, the organ that develops and implants in the mother’s uterus during pregnancy. Through the blood vessels in the umbilical cord, the fetus receives all the necessary nutrition, oxygen, and life support from the mother through the placenta.
Does baby get all nutrients from mother?

What week does baby get nutrients from mother?
Babies start absorbing nutrients from their mothers about three to five days after conception. That’s when the fertilized egg meets its energy needs with nutrients secreted from Mom’s endometrium (the tissue lining the uterus).
What is the last organ to be developed in a fetus?
Almost all organs are completely formed by about 10 weeks after fertilization (which equals 12 weeks of pregnancy). The exceptions are the brain and spinal cord, which continue to form and develop throughout pregnancy. Most malformations (birth defects) occur during the period when organs are forming.

When does a baby start getting nutrients from the umbilical cord?
Over the course of your pregnancy, the placenta grows from a few cells into an organ that will eventually weigh about 1 pound. By week 12, the placenta is formed and ready to take over nourishment for the baby.
