Detailed explanation-1: -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. The heart is enclosed in a pericardial sac that is lined with the parietal layers of a serous membrane.
Detailed explanation-2: -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.
Detailed explanation-3: -How big is your heart? Everyone’s heart is a slightly different size. Generally, adult hearts are about the same size as two clenched fists, and children’s hearts are about the same size as one clenched fist.
