@@lego102lego First of all, testicls don't help in respiration (ik just sarcasm). But my biggest shock was when he said that fish breathe the oxygen in H2*O* (fish breathe oxygen dissolved in water like how carbon dioxide is dissolved in soda) 😭 like whattttt I am into Science and I just entered high so whenever a grown up talks like that it hurts my heart 💔 And to top of the pain, he illustrated it with the oxygen atom (O), which is super inaccurate. You don't breathe the oxygen atoms, you breathe the diatomic oxygen (O2 molecule which has two oxygen atoms). There was no explanation of how oxygen diffuses into the bloodstreams through capillaries.
Just to be clear, fish do not breath the oxygen in the H2O itself (if they did, it would change the molecular structure of water - it would become HO which would no longer be water). They breath the oxygen that got into the water from air (O2) and now flows in there like all the other molecules. Edit: yes, I made a mistake. If the fish breathed in the O from H20 it would become H2 not HO. Thanks for all of the comments that are referring to that fact
thank you for this, for some reason i have found myself in multiple debates about whether fish can drown and this is always my argument, explaining that if water does not have enough oxygen in it, fish will suffocate.
People in the Jaws movies could had really benefitted from this information. All they needed to do was tie the rope at sharks tail and pull it on a motor boat. 🤣
Sharks breathe through ram ventilation. Which basically means they ram through the water to make it flow to the gills. So sharks suffocate when they stop swimming. (You don't have to pull them backwards)
Hold up. You almost got it. Gills don't suck the O out of the H2O itself, they absorb the 02 gas that's dissolved into the water. Water's a great solvent, after all. If they absorbed the O in H20, they'd be making hydrogen gas that would exit out of their gills.
This is the video i get after watching another video from lukes goldies explaining why fish need both water and oxygen to survive in a more detailed way lol
Fish don't use the O in H2O to breath, they use the O2 molecules that are dissolved in the water to breathe. Fish's gills cannot break down water molecules. Fun fact, they can't create hydrogen bombs either
Correction h2o is so hard to disolve there is disolved oxygen thats why in the aquarium u see bubles thats air getting disolved by a spetial pump so the fish can breath❤
That’s why tuna die when they stop, because from spawn they move forward so quickly that they are pulling water forward, and when they stop they suffocate.
Two things 1: capillaries are what cause hickeys if you suck on them 2: the way fish breathe is very similar to how ramjets work they use cones to aim the air that the plane is going through to get as much air as possible to work the jet
Actually, fish don't do any chemical reaction with the water. They just use the already existing O2 in the water. And that's why global warming is dangerous for them, because the hotter the water is, the less O2 it can carry around.
Fishes breathe oxygen through a process called respiration, but they do not separate the oxygen atoms from the water (H₂O) molecules. Instead, they extract dissolved oxygen gas (O₂) from the water. Here's how it works:Gills: Fish have specialized respiratory organs called gills. Gills are made up of thin filaments that are rich in blood vessels.Water Flow: Fish draw water in through their mouths and force it over their gills.Gas Exchange: As water passes over the thin-walled gill filaments, dissolved oxygen diffuses from the water into the blood vessels in the gills, and carbon dioxide (a waste product of metabolism) diffuses from the blood into the water to be expelled.Circulation: The oxygen-rich blood is then circulated throughout the fish's body, providing the necessary oxygen to tissues and organs.The key point is that the oxygen fish breathe is in the form of dissolved oxygen gas (O₂) in the water, not from breaking down the H₂O molecules. The concentration of dissolved oxygen in water can vary depending on temperature, salinity, and other factors, and fish have adapted various ways to maximize their oxygen intake.
