Most are. A notable exception is urine. The kidneys are able to concentrate the salts and nitrogenous wastes in the urine so as to conserve water. A dehydrated person will produce very concentrated, hypertonic urine.
Yes. Normal saline is isotonic. If you add sterile water to a sample of blood in saline, the erythrocytes will draw in the water and swell until they rupture.

An isotonic solution for human red blood cells is .85% sodium chloride. When the osmotic pressure is the same outside the cells and inside the cells, the solution is isotonic.
In isotonic solution cells reach a point called dynamic equilibrium.
isotonic, things remain the same

They are bathed in fluids such as blood that are isotonic
D5w and 0.9 ns are both isotonic solutions (osmolarity is similar to body fluids). When combined however, the solution becomes hypertonic (osmolarity is greater than body fluids). When administered iv, d5w .9 ns pulls fluid from cells and interstitial space into blood vessels.
If the cells are not isotonic, they are not in equilibrium. If the cell was in a hypertonic environment, the cell would become lysed and burst. If the cell was in a hypotonic environment, the cell would be deprived of fluids and shrivel. EX: when we take baths, our cells in our fingers absorb water and get pruny. when our cells are depleted or are starting to shrivel, we crave water to replenish them.
Crabs like other crustacians are isotonic to marine environment ,also called osmoconformers, theydont adjust concentration of body fluids .
A water solution that has the same salt concentration as the cells is said to be is isotonic.
An isotonic solution for human red blood cells is .85% sodium chloride. When the osmotic pressure is the same outside the cells and inside the cells, the solution is isotonic.

it produces antibodies that circulate in body fluids.
