Their skin. It is permeable to oxygen and carbon dioxide, as well as to water. On land, adult frogs use their lungs to breathe. When a frog is underwater, oxygen is transmitted through the skin directly into the bloodstream. Because the oxygen is dissolved in an aqueous film on the skin and passes from there to the blood, the skin must remain moist at all times.

frogs like to swim in the water and are more aquatic than terrestrial, but they have very well developed meaty leg muscles, (both the calf and the thighs) and many muscles the same as humans which they can use for hopping too. They just use their hind legs for hopping though.  Those puny little arms-hands-muscles are not used for much other than propping themselves up when sitting, or a male may squeeze a female when he is on her back mating with her.

The most amazing thing about the human body...\n\nReproduction? The heart? The brain? The digestive system? The circulatory system? Nah. None of these are the most amazing thing about our bodies, simply because these things can be done by other animals. The most amazing thing about the human body is the ability humans have to reason, to think creatively, and to act independent from a group. Basically, what sets us apart from animals is our ability to think through situations and come up with rational answers and solutions to problems.

No, the human body is a very large collection of atoms, the cells are made up of all sorts of things taht each could be divided into smaller things and that on the other hand maybe can bedivided into smaller things until you find that all that is left is atoms.

To the above mention person, idiot this is english if you are not versed in scientific terms don't go spouting nonsense. Cartilages are not true bone material, they are soft tissue like what our noses and most non skeletal fishes such as sharks and rays are composed of. But a toad has a skeletal structure and the cartilages are the same as a humans, found at the bridge of the nose area.

It is the comparative similarity in embryos of vertabrae orgaisms.  An example is if you look at several vertabrae organisms (example: human, chicken, turtle embryos) they will look similar.  This suggests that they have a recent common ancestor since they have similar developmental/early anatomical traits.

Frogs have a THREE chambered heart, not two. Oxygen poor blood flows from right atrium to the ventricle where it is pumped to the lungs and skin to pick up oxygen. Next the blood flows back to the heart, collecting in the left atrium. It them flows to the ventricle and is pumped to the body, dropping off the oxygen. This oxugen poor blood flows back onto the right atrium and it begins again.\n\nThis process is simular in humans except we have two ventricles, and do not breath through or skin as much so the right ventricle pumps to lungs only.

Birds, Definitely. birds, being warm blooded, are much closer to mammals than amphibians. Amphibians only show the faintest glimmer of an R-Complex, known in your brain as a cerebellum - the reptilian part of the brain. Birds, by contrast, have a highly developed R-complex and even show the beginnings of a cerebrum (the big lumpy part of your brain that handles all that rational though stuff). Can you imagine a frog or a salamander uttering, "Polly wants a cracker?" >:)

Most of these disorders are common between humans and animals because homo sapiens IS an animal and we therefore share the same basic cellular structure with all other animals. One classic example is diabetes (which can occur in animals besides humans; you don't see it much because it is selected against in nature), caused by improper functioning of the mitochondria through the lack of insulin production. Cyanide causes death by asphyxiation through almost the same process; the mitochondria cannot metabolize, and death results.

Amphibians are hunters; they eat anything from insects to birds and small mammals, reptiles, and other amphibians.  Frogs, for instance, huntby sight, and will go after anythign that moves in their path that is is a relative size to the prey they hunt (ie. flies, bugs).

Hello,\n\nThe frog is an ancient shamanic creature, it has alot of  symbolism assocaited with it. Why? because the frog is a creature that can move from one state to another state. i.e from & to the world of water & also move onto and off the land. So the frog is a creature which is about movement & change, about transformation.\n\n**Thus seeing alot of frogs tends to suggests ALOT of change or transformation or movement going on in your life, usually its assocaited with your inner self. Could be a change in emotions, or a change in relationship/s.\n\n**Water (which the frog moves to and from) is associated with the feelings or emotions, because normally feelings are fluid or flow. The direction of the emotions is the south.\n\n**Land (onto which the frog moves back & forth) is associated with the earth element, solid objects, material objects or in terms of the human body the bones,etc. The direction of earth is the west.\n\nIR

cell-tissue-organ-organ systems-organism (population)\nTissues are a group of specialized cells that perform a function. Organs are groups of specialized tissues that perform an even more complex function. Organ systems are groups of organs that perform a function in a series of complex, yet related steps. An organism is a body with  several organ systems necessary to maintain homeostasis. This can be extended to population which is several organisms existing together to survive (think food webs).\n\nUnicellular organisms do not have specialized cells. They have only one cell to perform all the functions it needs.

Similarities:\n1. Both project effects to remote sites in the body.\n2. Both use negative and positive feedback systems. (e.g. The parasympathetic and sympathetic nervous systems and the hormones with opposite effects).\n3. Both project effects on each other.\nDifferences:\n1. The nervous system usually responds to events that require a fast response, and are short in duration, while the endocrine system is usually reponsible for handling/regulating long-term things. \n2. The nervous system projects its effects to a discrete region. The endocrine system generally projects body wide.\n3. Sorry I can't recall a third attribute right now.
