like whale and shark can survive. Why?

Answer 1

Answer:

Here is your answer

Explanation:

Because human beings breathe through lungs whereas mammals like whale and shark breathe through a special organ gills. So they easily breathe in ocean. I think it may help you.

Answer 2

Since humans don't have gills, they can't separate oxygen from water for breathing purposes, therefore unable to survive.

Why is it so?

• Humans can't inhale submerged oxygen in light of the fact that our lungs need more surface region to assimilate sufficient oxygen from water, and the coating in our lungs is adjusted to deal with air as opposed to water.
• A few marine warm blooded creatures, similar to whales and dolphins, do live in water, however they don't inhale it.
• They have fostered an instrument to pause their breathing for extensive stretches of time submerged.
• Blowholes are a whale's noses and are situated on the top or back of the whale's head.
• Blowholes are covered by solid folds that hold water back from entering them when the whale is submerged.
