But Why: A Podcast for Curious Kids

Why do we have blood and what does it do?

<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>
