It is taken to the heart and pumped into the cells. At the same time, the carbon dioxide waste from the breakdown of sugars in the cells of the body diffuses into the blood and then diffuses from the blood into the lungs and is expelled as we breathe out. One gas (oxygen) is exchanged for another (carbon dioxide).

The respiratory system consists of all the organs involved in breathing. These include the nose, pharynx, larynx, trachea, bronchi and lungs.

Throat (pharynx) Voice box (larynx) Windpipe (trachea) Airways (bronchi)

Breathe in slowly through your nose. The hand on your stomach should move, while the one on your chest remains still. Breathe out slowly through pursed lips. Keep practicing this technique until you’re able to breathe in and out without your chest moving.

Alan Izhar-Bodner, an Israeli inventor, has developed a way for divers to breathe underwater without cumbersome oxygen tanks. His apparatus makes use of the air that is dissolved in water, just like fish do. (From Breathe like a fish!)

Tidal volume (TV) is the amount of air breathed in with each normal breath. The average tidal volume is 0.5 litres (500 ml). Minute ventilation (VE) is the total volume of air entering the lungs in a minute. The average minute ventilation is 6 litres per minute.

Scientists have discovered a way for humans to potentially breathe underwater by merging our DNA with that of algae. The real-life version however could work on a more fundamental level and change our DNA so that we are more like algae, which actually give off oxygen even though they are on the sea bed.

Living underwater is actually possible, and you could be moving to an underwater city in the near future. The idea of humans living underwater may not be as crazy as you think. An idea once reserved for video games or science fiction, underwater cities may be a viable solution for humanity in the distant future.

Fish also need oxygen to live, but their lungs are not designed to extract oxygen from the air. Since humans do not have gills, we cannot extract oxygen from water.

No, fish cannot survive in milk. Fish cannot breathe properly in milk due to low dissolved oxygen and the presence of impurities in milk. Therefore, fish may drown in milk within a few minutes.

Most fish do use air to inflate and deflate their bladder to maintain buoyancy which is expelled either through their mouth or gills which can be mistaken for a fart. Experts say that the digestive gases of fish are consolidated with their feces and expelled in gelatinous tubes which fish sometimes eat again (eew…

Oxygen-free living By making alcohol, crucian carp and goldfish can survive where no other fish can, meaning they can avoid predators or competitors.

Yes. Very small ones can easily be drunk by mistake or even on purpose. If the question means can fish get drunk from alcohol, then it is very likely that some alcoholic content in their water would affect them. The level would need to be very low otherwise the fish will be poisoned and die.

NO. Your fish will die before you notice any “drunk” behaviour. I have vodka-dosed my marine reef tank before, which was about 1,500 litres in size. The typical dosage was about 5-10ml for this size tank, and the purpose of putting this in was to see what effect this had on the level of dissolved nitrate in the water.

50 percent ethanol concentration), they throw their inhibitions out the window. They swim faster, and show little fear or hesitation. And when they’re around their peers, they go even faster—and surprisingly, the sober fish increase their speed to keep up.

Water completely absorbs (or attenuates) different colors of light at different depths, affecting which colors are visible to a fish. Water attenuates red light from the spectrum first, oranges and yellows next, and blues and greens last (see the chart below).

Fish can see braided line and that’s why you always want to use a fluorocarbon or monofilament leader. Matching the line color with the water you’re fishing in is also a good idea to limit your presentation’s visibility.

While many people believe it to be a fish attractant, The WD40 website addresses the question with the following statement on their website: While WD-40® can be used to help protect fishing equipment from rust and corrosion, WD-40 Company does not recommend using WD-40® to attract fish.

Green Light and White Light are the most common colors used to attract fish to Boats, Docks and Piers because they are brighter and will attract fish from a greater distance. Blue Light is less bright and is typically used more for aesthetic and ambient lighting and is commonly used around restaurant and resort area’s.

The salt makes the soft plastic softer. Fish tend to hang on to a bait longer if it contains salt. Some anglers swear by baits with salt in them, stating that they catch many more fish than other baits. …

Overall, green light attracts the most fish. Green has a high lumen output of 130 per LED alongside a 520 nm wavelength. Shrimp and insects have both of these wavelengths in their color vision alongside green light receptors around 530 um.

Any light under the water, no matter what the color, will attract fish. When lights are placed under the water, they reflect off particles in the water. These tiny little particles enhance a natural food source for bait fish.
