Why do humans die faster when they drink seawater, but whales and fish can drink it?

Because the human digestive system and bodily functions are unable to metabolize the salts and microorganisms in the seawater in time, whales and fish have adapted to the environment in the sea because they have lived in the sea for a long time.

Because there is a lot of salt in seawater, and human cell membranes cannot enter and exit freely, the internal and external penetration of whales and fish is basically the same as that of seawater, so they can drink seawater.

Seawater has a salt content of four percent, and the osmotic pressure of human body fluids and seawater is different, which can lead to massive dehydration of cells. The osmotic pressure in whales and fish is basically the same as that of seawater, so they can survive well in the sea.

We humans can only drink fresh water, and seawater is not drinkable, and it contains a lot of harmful substances. Whales and fishes can digest these things in their bodies, but we humans are very weak and can't drink seawater so roughly.

Seawater contains 90% table salt, which requires a lot of water to be excreted in the body. And seawater is not consistent with the penetration of bodily fluids in our body. The cell membrane does not allow salts to move in and out freely.

Too much salt will cause damage to the cell membrane and the body will become dehydrated and die. Whales use baleen to expel seawater after inhaling it. Saltwater fish will use their gills to filter out the salt.

Because the cells of living organisms in the ocean have a higher concentration of cell fluid, similar to seawater, their cells can tolerate the concentration of seawater. Human cells, on the other hand, have a lower concentration of cell fluid, and when seawater is drunk, the cells become dehydrated.

You should know that a solution with a high concentration will diffuse to a solution with a low concentration, and the last two solutions will have the same concentration.

The same is true of the principle of cells. As people evolved from water to terrestrial, the concentration of cell fluid began to decrease compared to the concentration of seawater, like a glass of light salt water and a glass of concentrated salt water, so that when you drink seawater, you become dehydrated. So people can't drink seawater.

But the fish are still in the ocean, and the concentration of their cell fluid is the same as that of seawater, just like the concentrated salt water meets the concentrated salt water, of course, they will not die, and they can survive better

Fish can pass.

to filter out the salt, but people can't. Marine fish have chloride cells that secrete chloride ions, mainly in the gills, and some fish in the mouth, **, these cells are constantly working to reduce the concentration of ions in the body. At the same time, marine fish drink a lot of water and absorb water through the digestive tract (freshwater fish generally do not drink water), and most of the water is absorbed by monovalent ions such as sodium, potassium and chlorine, while less than 20% of divalent ions are absorbed.

The death of a whale is a very big gift to marine life, once a whale dies, everything is born, and the fish, crustaceans, and consumers in the sea can all get a piece of the pie.

Provide a certain amount of food for the fish in the sea, so that they can find their own food faster, without having to do any robbery, and reduce the pollution of the ocean.

Seawater can be treated directly after purification.

For drinking, "Hyde Moisturize" is the product of purified seawater.

All living things have to complete the process of birth and death, and life refers to the length and duration of the process. Fish in the ocean also have to complete this process, but the carcasses are decomposed by the same or different species and the seawater, and they are not easy to find.

You grew up eating rice. Can it be compared to those who eat salt?
