it is the adrenal glands
urea ,water ,salt(excess)
Kidneys are the main organ, which excretes the salt from the body but then skin it hot tropical climate may loose large amount of salt through perspiration. Which may amount to one liter/ hour and may contain 3 grams/liter of salt in it.
Blood, Alcohol in beer, Sugar solution where the amount of water is in great excess. Basically, if it dissolves so that it cannot be seen it is homogenous. Homogenous means that it is dissolved well
dissolving sugar or even salt in water is a physical change, because the salt or sugar is no longer in the gradual form it was in before it was put in the water
When the body has too much salt in it, the kidneys will excrete the excess salt into the urine, and they will also increase the amount of urine produced, in order to more easily flush out the excess salt. But to produce urine, the kidneys also need to obtain water from the blood, and the body must replenish its supply in order to avoid dehydration. Hence, you get thirsty.
It excretes excess water.
the adrenal gland
sweat glands
The body excretes excess water through urination. It sweats to reduce the body temperature not to get rid of water.
The inner fluids of fish are not as salty as the sea water therefore fish have a special gland in their gills that separates the salt from their inner fluids and excretes it back out to the sea. For fish - living in salt water is no big deal. Land creatures get rid of their excess salt by flushing it out with a bunch of extra water. There is a maximum concentration of salt to water that the kidneys are able to produce they can not make pure salt they have to have excess water to get rid of it. So what do you think would happen if you can get no excess water? What if the only water you could get was already saltier than what you have in your body? A land animal drinking sea water would only get saltier and saltier, get sick and eventually die.
no, it excretes sweat which contains a form of salt
Due to its evolutionary descent from fresh water fish mammals get rid of excess salt by flushing it out with excess water. (Fresh water fish always had excess fresh water that was in need of getting rid of, so that is the method they developed and mammals inherited.) If a mammal drinks salt water it tries to get rid of the excess salt by excreting excess water and slowly dehydrates itself to death.
The liberal excretes excess cholesterol in bile
The skin excretes salts from it's surface. I don't believe that the liver does.
im pretty sure it is because of a special gland they have that saves the salt from whem there in the ocean and excretes it when they are in freshwater
urea ,water ,salt(excess)
The human body excretes the waste products through the skin on sweating, through the lungs due to exchange of gases and carbon dioxide is exhaled, urine which filters the blood and excretes urea and other electrolytes and the faeces which are the waste product of our diet which we eat every day
