The testes.
They have froggy kidneys
structural homology
In frogs, the kidneys are located higher in the body cavity, closer to the heart, compared to humans, where they are positioned lower in the abdomen. This difference is largely due to evolutionary adaptations and the distinct anatomy of amphibians versus mammals. Frogs have a more streamlined body structure for their aquatic lifestyle, while humans have evolved a different organ arrangement suited for bipedal locomotion and terrestrial life. Additionally, the positioning of kidneys reflects variations in function and the need for efficient waste filtration in different environments.
Frogs live both underwater and above (on land). They are amphibians.
err... maybe because the structure of the organs of a frog is most likely the structure & position of organs in a human's body... and frogs are easy to get or buy... and many species are not endangered! :) hopin' this can help!
Frogs can be found in all countries.
The oviduct.
Urine is waste from the blood that the kidneys filter from the body. Kidneys in the body of a frog function in the excretion of urine.
Leopard Frogs (also known as common frogs or meadow frogs) can be found in damp environments, in temperate parts of North America.
