because unlike mammals, sharks do not have lungs (like other fish) and the gills act as filters. They process oxygen through the water so they can breath thus the shark always has to keep moving (depending on the species of course)
Yes, white sharks have gills that allow them to extract oxygen from water, which is how they breathe underwater. They need to constantly swim to ensure a flow of water over their gills for oxygen exchange.
They breathe through lungs while on land,and by their skin while in water Through their skin.
Water is lost from the gas exchange surface of terrestrial organisms because gases must be exchanged with air. Terrestrial organisms have a high water potential, therefore when the gas exchange occurs water will be lost.
Mako sharks, thresher sharks and Great white sharks
megalodon sharks, great white sharks, frilled sharks, thresher sharks, tiger sharks, sand tiger sharks, lemon sharks, bull sharks, whale sharks, basking sharks, lepord sharks,black tip sharks. there is 12.
hello guys
In the lungs, exchange of gases occurs in the alveoli(sing: alveolus).
During the stage of photosynthesis, the exchange of gases occur in the leaves.
Light is necessary for the exchange of gases in plants.æ Light is what instigates photosynthesis and without photosythesis there can be no gas exchange.
the blood vessel which allows gas exchange to occur is the capillaries
The actual exchange of gases occurs in the alveoli
YES
by mating
it farts
yes
lower exchange rate,takes longer for gases to diffuse
The heart is not where gases are exchanged. This occurs in the lungs.
