Both humans and the frog have the same kinds of organs and systems of organs. The frog's anatomy, however, is much simpler. 1) General Body Features As in other higher vertebrates, the frog body may be divided into a head, a short neck, and a trunk. The flat head contains the brain, mouth, eyes, ears, and nose.

Some of the major amphibian characteristics that the frog exhibits is that it can breathe through its skin and lungs. Frogs also have webbed feet which is common of most amphibians. Frogs must live in moist environments to sustain life.

The shoulders and front legs of the frog are somewhat similar to human's shoulders and arms. The frog has one "forearm" bone, the radio-ulna. Humans have two forearm bones, the radius and the ulna. Both frog and human have one "upper arm" bone, the humerus.

Frogs also reproduce by laying eggs, in contrast to humans. 9. Human Frog 3. On the skin, the skin that envelops the human body is very soft and human skin pores are small.

A small round disc called the tympanum covers the ears of both male and female frogs. On males of most frog species, the circumference of this small disc is larger than the eye of the frog. On females of most frog species, the disc's circumference is equal to the size of the frog's eye.

Toads. Like frogs, toads are amphibians. They differ from most frogs because they have dry skin, warts, crests behind the eyes, and parotoid glands. The parotoid glands produce a poisonous secretion that helps the toad defend itself from predators.

Amphibia - Amphibians Amphibians are four-legged animals that don't have amniotic eggs. ... The larvae of most amphibians have gills and look like fish when they are born. They go through metamorphosis and grow four legs and develop air-breathing lungs when they become adults.

Humans are warm-blooded, amphibians cold-blooded. Frog hearts have three chambers, human hearts have four. Also, the electric currents that flow in the muscle cells of frog hearts have different features to those that flow in human hearts.

Their differences are that the frog's heart have three chambers and the kangaroo has four. Another difference is that while the kangaroos keeps the oxygenated and deoxygenated blood in different ventricles, the frog keeps both types of blood in the same ventricle.

The fourth and final stage of a frog's life is an adult frog. Remember, the frog's life cycle has four stages. First the egg, second the tadpole, third the froglet and the fourth stage is the adult frog. Frogs and Butterflies each have four stages of their life cycles.

Like their adult counterparts, frog tadpoles are slimmer whereas toad tadpoles are chunky. Frog tadpoles are also covered in gold flecks, while toad tadpoles are plain black in colour. Frog tadpoles have a thin tail and are dark with gold speckles.

Most mammalian red blood cells are highly evolved and have lost their nucleus. Unlike typical mammalian red blood cells, those from amphibians, such as frogs, contain a DNA-bearing nucleus that is visible in the center of the cell. All non-mammalian vertebrates have nucleated RBCs. So, the correct answer is 'Frog'.

Many amphibians, such as frogs, undergo a metamorphosis, meaning they begin life in the water and live on land as adults. Defining characteristics of these creatures include moist, scaleless skin and the fact that they are cold-blooded. Amphibians absorb water and undergo gas exchange through their skin.
