Your Physical Body: From Birth to Old Age (Your Body For Life)

Our bodies are always growing and changing - from before we are born until the day we die. Even when were asleep our hearts continue to beat, we keep on breathing, and the cells that make up our bodies are constantly being repaired and renewed. But how and why does this happen? This book looks at the physical changes our bodies undergo, from reflex actions and changes to bones, to the impact of wounds, disease, and ageing.
