Why do we have blood and what does it do?

But Why: A Podcast for Curious Kids

But Why is a show led by kids. They ask the questions and we find the answers. It’s a big interesting world out there. On But Why, we tackle topics large and small, about nature, words, even the end of the world. Know a kid with a question? Record it with a smartphone. Be sure to include your kid's first name, age, and town and send the recording to questions@butwhykids.org!

<p>Why do people have blood, what is it, and what does it do? How do our bodies make new blood? Is it red or blue? Why does blood taste like metal? And why do we have different blood types? Our listeners have a lot of questions about blood. We learn about blood with UVM Medical Center and Larner College of Medicine pathologist Dr. Sarah Harm. </p>
