Oxygen - yes. Air - no. Not much of that around underwater.
Squid use their gills to exchange gases, extracting oxygen from the water and releasing carbon dioxide. The gills are located inside the mantle cavity of the squid.
Dolphins actually have to surface to get oxygen from the air. Tuna and squid have special lungs called "gills" that allow them to remove oxygen directly from water.
Squid obtain oxygen from the water by passing it over their gills. As water flows through the gills, oxygen is absorbed into their bloodstream and carbon dioxide is released back into the water. This allows the squid to extract oxygen from their watery environment for respiration.
Air gives use Oxygen!
Squid use oxygen from seawater for respiration. The seawater enters the mantle through the opening near the head, and passes over the gills. Oxygen diffuses from the water into the blood, and is transported to the gill (or branchial) hearts by a network of many blood vessels.
Animals breathe in oxygen in the air.
People use air for oxygen, without air we would all be dead.
Squid have gills along their sides... thus obtaining oxgen similar to a fish
Organisms use the oxygen they absorb from the air for their cells. The cells need this oxygen in order to carry out their functions.
They use them to breathe with, to get oxygen from the air.
same way the fish do
Inhaled air has more oxygen compared to exhaled air. When we inhale, we take in fresh oxygen from the environment to use for cellular respiration. As we exhale, we release carbon dioxide and the remaining oxygen that was not used by the body.
