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)

∙ 10y agoThe respiratory system consists of the gills, gill rakers, the mouth, spiracles, gill lamellae, working together in conjunction with the circulatory system. Essentially, the goals of these systems are to absorb and circulate oxygen and other nutrients through the blood with the intention of distributing them to various parts of the body.

∙ 9y agoThere are many animals in the world that use gills as a way of breathing. Gills work by filtering the oxygen out of the water that passes through them, and helps it enter the blood stream.

What are two ways frogs can exchange gases?
They breathe through lungs while on land,and by their skin while in water Through their skin.
Why is water always lost from the gas exchange surface?
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.

How can leafs exchange gases in the absence of light?
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.

Where does the acual exchange of gasoccur?
The actual exchange of gases occurs in the alveoli
How would thick-walled alveoli affect the exchange of the respiratory gases?
lower exchange rate,takes longer for gases to diffuse
