no, we humans do not have gills because they have lungs unless they use the oxygen thing to go underwater
It could be possible
Actually, at no point do humans EVER have "gills," or even "gill slits." This common misconception was started in the early years of medicine. There are visible creases on the fetal neck that were originally thought to be remnants of past evolutionary stages. It is now known and commonly accepted that these creases are due to the formation of lymph nodes and lose visibility as the fetus matures.
There are few reasons humans cannot live underwater.The main reason, of course, would be that humans lack gills. The gills in fish and other underwater organisms allow the oxygen in the water to be used inside the body. Oxygen is very fundamental to our body; for it keeps us and our cells alive and functioning.Another reason is that in salt water (the ocean), if we did have gills and consumed the water, our cells will lose all of their water because they of the hypertonic environment and they will shrivel up.we can't live under water because our lungs don't take in water they take in air, if we don't have air in our lungs then we could not function right!Were not fish LOL :)
spiracles and tracheae
It depends on the kind. Some snails have gills while others have a single lung.
How would people find out anyways because science hasn't fully developed ways of predicting certain futures- therefore we have no proof whatsoever that humans may form gills although you can never be positive for it is something that cannot be forseen. Part of the embryonic time of human development includes gills already. Then we develop past it.
Lungs are for humans,gills fish
through their gills.
lungs.
No, They receive oxygenated blood through the umbiliacl cord, humans do not have gills.
because humans do not have gills.
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.
because they both get boners
Sharks are a type of fish. This is because fish are defined as being vertebrates with gills.
Fish do not breathe through their mouth like humans. They have gills which the use to filter the oxygen from the water.
Animals can survive by their gills and they have oxygen in their gills. Humans have been able to survive in the ocean only because of aqua lung and also submersibles also known as submarine's
No Gills, we have lungs which we breath in and out with our mouths.
