The sternum of a rat, like in other mammals, serves as a central point of attachment for the ribs, contributing to the ribcage's structural integrity and protecting vital organs such as the heart and lungs. It provides leverage for respiratory muscles, aiding in breathing by allowing the ribcage to expand and contract. Additionally, the sternum plays a role in supporting the overall posture and movement of the rat. Overall, it is crucial for both protection and respiratory function.
To help rats to breathe
Yes. I believe all mammals do.
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.
a rat's heart beat is almost fast enough so you can't tell one from the other. veeeeeeeery fast.
The lung function of a rat is to take in oxygen you breath and take it to the blood. Then it releases the carbon dioxide from your body.
