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: -Your heart is a vital organ. It is a muscle that pumps blood to all parts of your body. The blood pumped by your heart provides your body with the oxygen and nutrients it needs to function. Your heart is about the size of a clenched fist, and weighs between 300 and 450 g.
Detailed explanation-3: -It is approximately the size of a man’s fist (230-350 grams) and is shaped like an inverted cone. About two thirds of the heart’s mass is located to the left of the body’s midline.
Detailed explanation-4: -If you’re a kid, your heart is about the same size as your fist, and if you’re an adult, it’s about the same size as two fists. Your heart beats about 100, 000 times in one day and about 35 million times in a year. During an average lifetime, the human heart will beat more than 2.5 billion times.
