Detailed explanation-3: -The human heart is a four-chambered muscular organ, shaped and sized roughly like a man’s closed fist with two-thirds of the mass to the left of midline.

Detailed explanation-4: -The shape of the heart is similar to a triangle, rather broad at the superior surface and tapering to the apex (see Figure). A typical heart is approximately the size of your fist. Given the size difference between most members of the sexes, the weight of a female heart is smaller on average than the male’s heart.
