Human's and bullfrog's both breathe through their nose but frog's can also breathe through their skin.

The humerus bone can be found both in a bullfrog and a human. Bullfrog's only have nine vertebrae while human's have twenty-four.

Human's have a seperate urinary system and seperate genital system while in a bullfrog it is called a urinogenital system where they both come together. Human's and bullfrog's both contain two kidneys in their urinary systems.

One similarity between a human's and bullfrog's digestive system is that they both have a liver and pancreas. One difference is that a bullfrog's tongue is attached from the front so it's able to extract out and latch onto its prey. Human tongues are attached from the back.

Female human's and frog's both have their eggs fertilized by sperm from the male. One difference that sets them apart would be that bullfrog's reproduce externally while human's reproduce internally.

Skeletal

One similarity between a bullfrog's and a human's respiratory system is that air enters the body through the nose, passes through the windpipe, and then is received by the lungs. One difference between them is that a frog's chest muscles are not involved in breathing while a human's are.
