The weight of the human heart can vary based on factors such as age, sex, and overall health. On average, an adult human heart weighs about 250 to 350 grams (8 to 12 ounces). However, these figures are general estimates, and individual variations are common.

It’s important to note that the size and weight of the heart can change over time due to factors like cardiovascular fitness, medical conditions, and lifestyle. Regular exercise, for example, can contribute to a healthier and more efficient heart.

While the heart is a relatively small organ by weight, its role in pumping blood and ensuring the circulation of oxygen and nutrients throughout the body is vital for overall health and well-being.
