Understanding Our Muscles

Without muscles we would not be able to move. Muscles keep our digestive system working too, and our heart is a large muscle that works all the time. This book looks at how muscles, tendons and nerves all work together to help us move every part of our body.

Fara muschi nu ne-am putea misca. Muschii ne mentin si sistemul digestiv functional, iar inima noastra este un muschi mare care functioneaza tot timpul.
