No, all hearts are not the same size.
While the heart is often described as being about the size of a fist, there are variations in size based on individual factors, particularly sex. The provided reference gives specific average dimensions and weights for both male and female hearts.
Average Heart Size and Weight:
Here's a breakdown of typical heart sizes and weights:
| Feature | Typical Size |
|---|---|
| Length | 12 cm (5 in) |
| Width | 8 cm (3.5 in) |
| Thickness | 6 cm (2.5 in) |
| Sex | Typical Weight |
|---|---|
| Female | 250–300 grams |
| Male | 300–350 grams |
As demonstrated above, male hearts are generally larger and heavier than female hearts, indicating that the size varies among individuals. The differences in weight are a direct result of the general size disparity between the sexes.
Key Takeaways:
- Individual Variation: Although the "fist-size" analogy is common, heart size varies from person to person.
- Sex Differences: Male hearts are typically larger and heavier than female hearts.
