Guest guest Posted January 4, 2011 Report Share Posted January 4, 2011 The adult heart is about the size of a clenched fist and weighs between 250 and 390 grams in men, and 200 to 275 grams in women. It is located in the centre of the chest cavity and is tipped diagonally, with about two-thirds of its bulk left of the body's midline and the apex pointing left. The heart is suspended in the chest cavity in a multilayered membrane called the pericardium which helps keep it in place. http://www.safeurlives.com Quote Link to comment Share on other sites More sharing options...
