950 - What are red and white blood cells, and what do they do?

There are three main types of blood cells: red, white, and platelets. Let's focus on red and white blood cells.

  1. Red Blood Cells (RBCs): They're like delivery trucks. Their job is to carry oxygen from your lungs to all parts of your body and bring back carbon dioxide, which is bad stuff your body doesn't need. Red blood cells have a special protein called hemoglobin that helps them do this.

  2. White Blood Cells (WBCs): They're like superheroes. Their main job is to help fight infections and keep you healthy. There are different types of white blood cells, but they all work together to find and destroy germs like bacteria and viruses.

In simple terms: red blood cells deliver oxygen, while white blood cells protect your body from sicknesses.
