The average heart weight of a rat typically ranges from about 1.5 to 2 grams, depending on the rat's size and age. This small size reflects their overall body weight, which is generally around 200 to 500 grams for an adult rat. Factors such as genetics, diet, and health can also influence heart weight in individual rats.
