What is angiogenesis?

Angiogenesis is when new blood vessels grow from old ones, like how a tree can sprout new branches.

Imagine you're playing with clay. You start with a big lump, that’s like the original blood vessel. Now, if you push your finger into it and make little indentations, those are like new paths for blood to flow through. That's what happens during angiogenesis, tiny new vessels branch off from bigger ones.

When you're healing a scrape or growing taller, angiogenesis helps by bringing more nutrients and oxygen where they’re needed most. Think of it like adding more roads in a busy city so more cars (blood cells) can get through faster.

Sometimes, too many new vessels grow, like when you press your finger into clay too hard, making lots of small bumps all over. This can happen in the body when there’s a tumor, and it helps the tumor grow stronger by getting more food and oxygen.

Angiogenesis is like a growing tree, always adding new branches to help things grow better!
