3d rendered medically accurate illustration of a fetus in week 7

The baby has doubled in size and is about half an inch long. The baby’s hands and feet are developing. His kidneys are also developing. Your baby still has a small tail (extension of her tailbone). The tail will disappear within a few weeks, but that’s the only thing getting smaller. His eyelids cover his developing eyes, and the tip of his nose and tiny veins are developing. The baby’s brain is growing, and his liver produces red blood cells until the bone marrow forms and takes over. He also has an appendix and a pancreas. A loop in your baby’s growing intestines is forming into your umbilical cord, which will carry oxygen and nutrients to and from his body.

This week the umbilical cord, the link between the baby and the mother’s placenta, is visible, and is starting at the site where your baby implanted in your uterus. The umbilical cord is made up of two arteries and one large vein. Nutrients and oxygen-rich blood pass from your placenta to your baby through the single vein and flows back to the mother’s placenta through the two arteries.
