Aside from the weight of the heart, there are a lot of differences between male and female hearts. Since these differences are internal, one will not be able to spot them without proper testing. For instance, it is found that the heart in females has chambers that are smaller when compared to the chambers of a male heart. This can prove that the women’s hearts tend to be smaller in comparison to the male heart. Apart from that, there are also some differences in the density of the male and female hearts. While the female hearts tend to pump blood faster, the amount of blood ejected by the male heart is more.
