Red blood cells, the body’s police force, are created in the bone marrow but sometimes, the factory breaks down and wayward policemen come out. Uh oh!
The world of cells is incredible! Activating enzymes, stopping viruses, and managing the body’s police force: it’s all in a day’s work for Teacher.
After the first cell is fertilized, division and diversification take place to create the 60 trillion cells of the human body.
The body’s police force is taught to neutralize its enemies (microbes and viruses), which reproduce at an alarming rate! It’s a very complex task.
