Though frogs are amphibians and humans are mammals, they both have very similar anatomies. Both consist of organs, bones, muscles, and skin and their bodies can be separated into limbs, trunk, head, and neck. Both species contain the same basic organs.
Frogs possess a pair of specialized organs called vocal sacs, which allow them to produce loud mating calls, a feature that humans do not have. Additionally, frogs have a unique structure known as a nictitating membrane, a transparent eyelid that protects their eyes while maintaining visibility. They also possess a cloaca, a single opening for excretion and reproduction, whereas humans have separate openings for these functions.
Leopard Frogs (also known as common frogs or meadow frogs) can be found in damp environments, in temperate parts of North America.
Snakes, birds and fish also eat frogs. Cheers, 99
Most frogs have lungs, but their are lungless frogs. They can also breath thru their skin.
fish and frogs also humans and turtles
Frogs have webbed feet for swimming, humans dont, Frogs have gills, Humans dont, and if they do not have gills, then they can hold their breath longer than any human could. Also, Frogs lay their eggs in water, which turn into tadpoles, and then frogs, our young are live born, and can only breathe air throughout their whole life.
Frogs are very complex and their organs such as the liver can be different from the humans. The liver is huge in the frogs anatomy. Also the rectum and large intestine are one combined organ. The body structure, or anatomy, of the frog is very similar to the anatomy of man. Both man and the frog have the same kinds of organs and systems of organs. The frog's anatomy, however, is much simpler. As in other higher vertebrates, the frog body may be divided into a head, a short neck, and a trunk (see Vertebrates). The flat head contains the brain, mouth, eyes, ears, and nose. A short, almost rigid neck permits only limited head movement. The stubby trunk forms walls for a single body cavity, the coelom. Man's internal organs are housed in one of three distinct hollow cavities--the chest, the abdomen, and the pelvis. The human chest is separated from the abdomen by a powerful muscular partition, the diaphragm. There is no such partition in the frog's coelom. All the frog's internal organs--including the heart, the lungs, and all organs of digestion--are held in this single hollow space.
Frogs breathe just like humans, taking in air through their mouths and exhaling it. They are also able to breathe through their skin.
Frogs and humans both have similar internal organs such as the heart, lungs, liver, and kidneys that serve similar functions in both species. Externally, both frogs and humans have eyes, a mouth, limbs, and a reproductive system, although the structures may be adapted to suit each species' specific needs.
Frogs have a much simpler digestive system compared to humans, with a single-chambered stomach while humans have a complex four-chambered stomach. Humans have a longer small intestine for nutrient absorption, while frogs have a shorter one. Frogs have a large sac-like structure called the gall bladder to store bile, while humans have a gall bladder but it is not as prominent as in frogs. Frogs have a single opening for both ingestion and excretion called the cloaca, while humans have separate openings for these functions. Frogs have a specialized organ called a cloacal bursa for water absorption, which humans lack. Frogs have a shorter large intestine compared to humans.
vestigial organs such as a tail bone in humans and a hip bone in whales. also, the skeletal structure of wings of birds, flippers of whales, and hands of humans are all very very similar in structure.
