The heart lies underneath the sternum, or chest bone, and sits a little to the left. The heart is located between the lungs and lies in front of the backbone. It is about the size of a fist. (This answer provided for NATA by the University of Montana Athletic Training Education Program.).
An average adult heart is 12cm from base to apex, 8 â 9 cm at its broadest transverse diameter and 6 cm anterioposteriorly. Typically, the human heart weighs between 250 and 350 grams, that is less than a pound.It is a hollow, fibromuscular organ of somewhat conical or pyramidal form. It has a base, apex and a series of four surfaces and four borders.
