Recall which of the following descriptions best describes how oxygen dissolved in sea water is extracted by sharks. It diffuses into capillaries inside the lamellas in their gills It diffuses into capillaries inside the lamellas in their lungsIt is captured by chemical reactions on the lamellas in their gillsI'm not sure

Sharks exchange oxygen and carbon dioxide with sea water across the surfaces of millions of tiny lamellas in their gills.Explain why they need so many lamellas.

By having the blood flow in the opposite direction as the water, gills maximized the diffusion of oxygen. This process is calledosmoregulationgastrulationcounter-current exchangehomeothermy

Question 5SavedSharks exchange oxygen and carbon dioxide with sea water across the surfaces of millions of tiny lamellas in their gills.Explain why they need so many lamellas.

here are a few fish that can obtain oxygen for brief periods of time from air swallowed from above the surface of the water. Thus lungfish possess one or two lungs, and the labyrinth fish have developed a speci
