How do fish get oxygen to respire?
Fish are equipped with two sets of paired fins and several unpaired fins. Most fish exchange gases by using gills that are located on either side of the pharynx. Gills are made up of threadlike structures called filaments. Each filament contains a network of capillaries that allow a large surface area for the exchange of oxygen and carbon dioxide. Fish exchange gases by pulling oxygen-rich water through their mouths and pumping it over their gill filaments. The blood in the capillaries flows in the opposite direction to the water, causing counter current exchange. They then push the oxygen-poor water out through openings in the sides of the pharynx. Some fishes, like sharks and lampreys, possess multiple gill openings. However, most fishes have a single gill opening on each side of the body. This opening is hidden beneath a protective bony cover called an operculum.
Where in the lungs do you exchange gases?
In the lungs, exchange of gases occurs in the alveoli(sing: alveolus).
Where does the exchange of gases occur in the plant?
During the stage of photosynthesis, the exchange of gases occur in the leaves.
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.
What blood vessels do the exchange of gases occur?
the blood vessel which allows gas exchange to occur is the capillaries

How does a platypus exchange gases?
it farts
How do lions exchange gases?
by mating
Do you exchange gases in the lungs?
YES
Does prokaryotic exchange gases?
yes
How would thick-walled alveoli affect the exchange of the respiratory gases?
lower exchange rate,takes longer for gases to diffuse
