because the frogs skin is served as a supplementary organ of gas exchange frogs use their tiny little lungs to breath when they are on land. so if they had huge lungs then they would just be in the way because the whole part of the lung was not in need! :D

Why are a frogs heart and lungs so close together?
The heart and lungs are so close together because the lungs have oxygen that are pumped into the heart so it can go into the blood stream. The lungs don't have blood but they transmit oxygen to the heart for the blood stream.
Do frogs have more musical ability than humans?
well a tree frogs hearing is kinda good because they have a hear drum but they block it out
What is the difference between a human and frog respiratory system?
LungsHumans breathe exclusively through their lungs, but frogs use their lungs for only part of their respiration. Frog lungs have thinner walls and are almost like balloons. They often fill their lungs to help them stay buoyant when swimming. Both species have bronchial tubes leading to the lungs, but human systems are more complicated, with many branching bronchiole. The lungs of frogs and humans have alveoli, tiny vessels that make the actual gas exchange. But the alveoli in humans are more densely packed because we breathe only through our lungs.DiaphragmAs humans, we use our diaphragm muscle to push up on our lungs and help us breathe out. Contracting the diaphragm, which sits under the lungs and separates our thoracic cavity from the abdominal cavity, pushes air out. Releasing the diaphragm lets the lungs stretch back out, making room for air you're breathing in. Frogs don't have a diaphragm. Instead, they use muscles in their throat sacs to help draw in air and push it back into the lungs.SkinFrogs have another organ they use to breathe: their skin. Frogs can exchange oxygen for carbon dioxide through their skin, but it needs to be moist for the process to work correctly. That's why you typically see frogs near water or burrowed in damp soil. Frogs' skin is an efficient breathing machine, exchanging carbon dioxide 2 1/2 time faster than their lungs can. In comparison, humans eliminate less than 1 percent of the necessary carbon dioxide through the skin.MouthsIf you've never seen a frog yawn, it's because they don't. They don't breathe through their mouths, only through their noses. We, on the other hand, have a choice of breathing through our noses or our mouths, or both. Frogs use muscles beneath their jaws to help move air, but their mouths stay closed while they breathe.
How do the lungs of a frog differ from those of the pig?
The lungs of a pig is larger and more evolved than that of a frog. This is because the frog has other organs of respiration apart from the lungs e.g the skin (cutaneous respiration) and mouth(buccal respiration) hence does not depend on the lungs solely for respiration unlike the pig which has thev lung as its only respiratory organ
What does a pike need to survive?
If you mean food, its zooplankton and insects and smaller fry when the pike is very small.Later it is smaller fish,frogs,ducklings,other pike. Even Later any kind of fish and small mammals and smaller birds. Waterquality : enough oxygen(nothing less than 3ml/per liter,pH higher than 4,2
What are the similarities of the glottis between humans and frogs?
I have heard that a frogs glottis is larger than a humans...
How are the frogs air sacs similar and different from human lungs?
human lungs help us breath in the air. while frog lungs hold air in so they can swim longer than humans. frogs can breathe through their lungs. we can't
Why do big frogs pick on little frogs?
Because the smaller frogs must do whatever the larger frogs command, or else, if angered or hungry, the larger frogs eat the smaller frogs. Well, basically, older and bigger ones have more power than the younger and smaller ones.
Do frogs have more offspring than humans?
Yes
Why are a frogs heart and lungs so close together?
The heart and lungs are so close together because the lungs have oxygen that are pumped into the heart so it can go into the blood stream. The lungs don't have blood but they transmit oxygen to the heart for the blood stream.
Why do frogs and worms have so many capillaries in this skin and humans do not?
Frogs and worms do have in their skins than humans because they breathe through the skin.
Can a human brain think more or can a frog's brain?
A frogs brain is different than a humans beacuse they think about different things than humans do and they have a smaller brain with alot more blood cells, but humans have lots of blood cells too.
What does a frogs skin do differently than humans?
it absorbs water
Is it true that a cow's lungs is bigger than a humans lungs?
Yes. Cows are much larger than humans are, thus need more oxygen to take in in order to function.
Compare the body cavity of the frog with that of man?
Actually, although they don't look similar at all, frogs and humans do have similar anatomy. Both frogs and humans have a heart, lungs, kidneys, a stomach, a liver, small intestine, large intestine, spleen, pancreas, gall bladder, etc. Of course, the frog's anatomy is much simpler than a human being's, because frogs do not have ribs, and they also don't have a diaphragm. And while frogs have a tongue, theirs is long and sticky (good for catching flies), while the human tongue is not; frogs also have teeth, but theirs are so weak as to be almost useless. Frogs can also breathe through their skin when underwater, while humans cannot. I enclose a good link to a site about frog anatomy.
Why do females inhale less air than males?
Generally speaking they are smaller framed and have smaller lungs.
Is there a difference between children and adults lung capacity?
Yes, children's lungs are smaller than adults lungs.
