Mayes 4th Grade Human Body Review

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

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

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

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

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

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

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

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

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

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

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

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

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