they leave through sweat
The waste products that leave through the skin are water, urea, ammonium and uric acid. Some sebum (oils) is also lost.
The integument system is the skin and does have the ability to help remove waste. Salts, water, urea and ammonia are lost through the skin.
the waste materials are deadcells,excess salts and water
Ground water can leave behind dissolved salts when it evaporates. As these salts accumulate they can have a very negative effect on desert plants or agriculture.
Large Intestine
Mostly urea, salts and excess water.
Water intake is important in order to maintain a constant plasma osmolarity (concentration of salts and other chemicals), and for the kidneys to efficiently remove waste products. (Take this as a long yes.)
the waste materials are deadcells,excess salts and water
Water enters the body through ingestion, and is absorbed into the blood.When it enters the kidneys, it meets with salts, urea, and other waste substances, where it produces urine.
Salts are soluble. The phospholipid bilayer membrane of cell walls are permeable to water and thus allow water and water-soluble substances, like salts, diffuse through.
The water salts and sugars will match the water concentration within the blood cell, therefore water does not enter or leave the cell, resulting in the cell not swelling.
Sports drinks replace electrolytes (salts and minerals lost through sweat); but can still leave you thirsty.
