How do fish breathe?

“How do the fish breathe?”. This question could have been asked by a little boy about five or seven years old while he was watching carefully a pond full of aquatic vertebrates.exactly the same? It is that it is in the early stages of our lives when curiosity manifests itself so frankly, so spontaneously, that everything is sought because… even to what we usually take for granted.

Adults, in As for these issues, we usually opt for the easy way and answer: “it is their nature and biologically they are prepared for this” , when the explanation is a bit more complex, although many intrigue us how they do these sea creatures to get some oxygen to survive.

How do fish breathe?

We don't have to be geniuses to recognize that humans would drown if we submerged for a few minutes at sea-if we do not have some equipment that provides us with oxygen artificially-.The same would happen to other mammals that are on the earth's surface, since we can receive oxygen efficiently only if our lungs remain free of liquids with each air inhalation.which is not so different in fish, even though they are in the water.

How do fish breathe?

Taking the above into account, how do fish breathe without their airways being filled with fluid? This is where the process becomes interesting. The fish do not have lungs , but they have efficient absorption mechanisms that allow them to extract oxygen from the water without being filled with liquid.The gills, located Commonly on both sides of the head, those laminates that contract as if they were some floodgates, are responsible for executing this extraction in such an extreme environment, because the water is 800 times denser than the air .

How do fish breathe?

When we see the fish, we notice that they often open and close their mouths , they do this to let some water pass, pump it and deoxygenate it by means of the gills.They close, that's when a small amount of liquid passes to these organs with which the limited percentage of oxygen dissolved in their natural habitat is used./p>

In its course, oxygen is transferred to the blood , travels to the cells and is distributed throughout the body by pumping the heart .This process of cellular respiration also produces carbon dioxide, which is eliminated with the same mechanism to prevent the poisoning of these vertebrates.Basically the gills or gills serve as a filter, and at the same time as lungs, so that respiratory function occurs.
