What body systems have the cloaca as the opening for frogs?

All amphibians have digestive, excretory, and reproductive systems. All three systems share a body cavity called the cloaca. Wastes enter the cloaca from the digestive and excretory systems, and gametes enter the cloaca from the reproductive system.

How are humans and frogs similar?

Scientists found additional similarities between the frog genes and human genes. For instance, genes in frogs have very similar neighboring genes as humans about 90 percent of the time. In other words, the frog genome contains the same sort of “gene neighborhoods” as the human genome.
