This week the umbilical cord, the vital link between your baby and your placenta, is clearly visible at the site where your baby implanted in your uterus.

The umbilical cord contains two arteries and one large vein. Nutrients and oxygen-rich blood pass from your placenta to your baby by way of the single vein and then back to your placenta through the two arteries. It takes about 30 seconds for a blood cell to make the entire trip.

In addition, your baby's brain is continuing to become more complex. Cavities and passages necessary for circulation of spinal fluid have formed. Your baby's growing skull is still transparent. If you were able to get a look at it under a magnifying glass, you might see the smooth surface of your baby's tiny, developing brain.

Your baby's face is taking on more definition this week. A mouth perforation, tiny nostrils, ear indentations and color in the irises of the eyes are now visible. The lenses of your baby's eyes are forming. The middle portions of the ears are connecting the inner ear to the outer world.

Your baby's arms, legs, hands and feet are taking shape, though the beginnings of fingers and toes are about a week away. The arm bud that sprouted just last week has already developed into a shoulder portion and a hand portion, which looks like a tiny paddle.

At seven weeks into your pregnancy, your baby is /3 of an inch long, a little bigger than the top of a pencil eraser.
