What does the heart do? Your heart, made of  muscle ,  pumps  blood  around your body via  blood   vessels  (tubes). The heart is inside your chest,  protected by bones - the  ribs  and  breast bone. When the heart pumps, it beats - we  measure the heartbeat via the  pulse   - easily found on your wrist and neck. Blood carries  oxygen  to the parts of  the body that need it.
