Life and death of cells

Every second of the day, millions of your cells are dying and being replaced. The instant skin, bone, blood and gut cells are worn out they are replaced, but brain, heart and cartilage cells are never replaced and have to last all your life.

Growing bodies

We grow from a single cell to an adult by increasing the number of cells in our body.

Bodies in balance

Your body is held in a constant balance of cells dying and cells being renewed.

Cells for life, cells for an instant

Every six seconds of your life, you make 200 000 new red blood cells, but no brain cells.
