Answer 2

The heart is well-protected because the heart is located in the chest between the lungs.                                                          

  It is exactly behind the sternum and above the diaphragm. So we can say that it is surrounded by the pericardium. Further lungs are surrounded by ribs bone so overall our heart is protected from ribs, lungs, and diaphragm.    

  The walls of the heart also contain cardiac muscles which support its structural features.
