Welcome back to The Science Edit A–Z of Biology!

In this episode, we’re exploring blood. Blood is far more than just a red liquid flowing through your veins. It’s a remarkable tissue that transports oxygen, nutrients and hormones, removes waste products and plays a vital role in protecting your body from disease.

We’ll take a closer look at the four main components of blood, discover how each one keeps you alive and healthy, and explain why understanding blood is so important for GCSE and A Level Biology.

Whether you’re revising for an exam or simply curious about how your body works, this episode has something for you.
