Shark have gills, just like fish, that water flows through. Oxygen in the water is absorbed by blood rich capillaries in the gills, which then circulates the oxygen to the rest of the sharks body.
No, sharks do not breathe air. They have gills that extract oxygen from the water as it flows over them, allowing them to extract oxygen from the water and breathe efficiently in their underwater habitat.
Sharks use gills to extract oxygen from water. As water flows over their gills, oxygen is absorbed into their bloodstream and carbon dioxide is released back into the water. Sharks must keep swimming to ensure a constant flow of oxygen-rich water over their gills.
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.
Bivalves obtain oxygen through their gills, which are feathery structures that extract oxygen from water as it passes through the bivalve's mantle cavity. The gills have a large surface area for efficient oxygen exchange, allowing the bivalve to breathe while submerged.
Sharks cannot stop moving because they always need oxygen flowing through their gills. Unlike other fish, who are able to "pulse" their gills in order to keep water and oxygen flowing through their gills, sharks are unable to do so and therefore have to keep swimming.
Sharks are a fish. Fish have gills that extract oxygen directly from the water in which they live.
Our body obtain oxygen to our body by breathing.
Sharks will usually sleep in a moving ocean current so that water flows through their gills constantly. plus they never really sleep as like you or I do their bodies are always in motion If their bodies are not in motion, they will sink.
Crustaceans obtain oxygen through gills.
from eggs and sharks
Who is "they" ?
you obtain oxygen from your lungs you could breath through your nose and through your mouth
multicellular organisms obtain their oxygen through the respiratory system
Sharks have gills on the side of there neck to filter oxygen from the water :]
We obtain oxygen by breathing in fresh air. Carbon dioxide comes out of us.
Their gills pick up oxygen while they swim
They use their gills to extract the oxygen from the water flowing over them
