5th Grade Human Body Review

We are blood vessels that send blood away from the heart.

I make bile. I store nutrients your body needs.  I make antibodies to hep you fight disease.

When you eat, I mix chemicals with your food to break them down. I contain acid.

I use villi to absorb nutrients from your food and put it into your bloodstream.

We are blood vessels that send blood back towards your heart.

I hold your body parts in. I let you sweat through pores. I contain nerves that help you feel.

We clean your blood. We take liquid waste from blood and send it to your bladder.

We give your body support and structure. We also protect delicate organs. I contain marrow.

I control your muscles and all of the organs in your body. I hold your thoughts and memories.

I am sometimes called the "windpipe." When you breathe air travels through me to your lungs.

Your body can't use every part of the food you eat. The waste comes to me and I dry it out.

We take oxygen and put it into your bloodstream.  We take carbon dioxide and send it out.

I am a tube in your throat. When you swallow, I carry food to your stomach.

We work in pairs to pull bones in different directions. We help move food through the body.

I am a muscle by your lungs. I am always moving. I pump blood to all parts of your body.
