The reproduction of bullfrogs is quite similar to humans', given that both vertebrates mate, however, the placement of certain reproductive organs on a male are found to be different. The testicles of a male bullfrog are found to be inside of their body right above the kidneys, whereas the testicles on a male human are placed outside of the body.

The skin of the bullfrog is proven to be incredibly unique. Though it is a soft outer covering for the body just as a human's, its function is quite different. The skin of the bullfrog is designed so that it can absorb water into the body making it unnecessary for the frog to take in water through the mouth this role that the skin plays is very convenient given that their habitats are very wet.

The exchange of oxygen in humans and frogs is very similar. Basically oxygen is diffused into the capillaries where it will have a high concentration of carbon dioxide, and from there it will go on through the alveoli. This process being the same in both humans and frogs is different as well. In frogs an initial gas exchange can already have taken place when a human must bring air into their lungs before any gas exchange may occur.

Skeletal

The skeletal systems of frogs and humans are found to be incredibly similar, especially looking into the limbs, which all carry the humerus, radius, and the ulna. When looking specifically at the skeletal structure of a frog, however, you will notice their bones are more diffused together such as their radius and ulna.

Frogs and humans are found to share several features in the digestive tract such as little finger like structures called villi. The villi in both frogs and humans work to absorb nutrients in the small instestine. Since frogs tend to have a smaller small intestine than humans however, the digestive process is a little different. Most of the nurtient absorption of humans will occure in the jejunum whereas in a frog will occur in the ileum.

The urinary system in both humans and frogs is pretty basic. Urine is formed, sent to the bladder and then released when the bladder has reached an extent. These functions are not the only functions of a frog's urinary system, however. In frogs, the urinary bladder also serves as a water supply incase of any heat or dry conditions.
