How does a placenta feed a baby before it is born?

What Crafty Clover says in this video

Intro

Hi there, curious minds! I'm Crafty Clover! Let's discover something amazing. How does a placenta feed a baby before it is born?

The Big Idea

Before birth, a baby needs food and oxygen. How does it get them? Through the placenta!

A Special Organ

Step one: A Special Organ. In placental mammals, a special organ called the placenta grows in the mother's body. It connects to the baby by a cord.

Food and Oxygen

Step two: Food and Oxygen. The mother's blood brings food and oxygen to the placenta and passes them to the baby. The baby's waste goes the other way.

Growing Longer

Step three: Growing Longer. The placenta helps the baby grow longer before birth. So the baby is more ready for the world when it's born.

A Closer Look

Let's take a closer look! Connects. Passed in. Passed in. Passed out.

Quick Facts

Quick facts! The cord leaves a mark called a belly button. A cord links the baby. Oxygen reaches the baby. Most mammals have a placenta.

Think Like a Scientist

Now, think like a scientist! Draw a mother and baby with a placenta and cord. Add arrows labeled food and oxygen going to the baby. Add arrows labeled waste going back. Color your picture. Find your own belly button!

Outro

In placental mammals, the placenta grows in the mother and connects to the baby by a cord. It passes food and oxygen to the baby and carries waste away, letting the baby grow longer before birth.
