What sort of environment (hypertonic, isotonic, hypotonic) does consuming excessive amounts of pure water create in the body flu
Vlada [557]

Consuming excessive amounts of pure water creates hypotonic environment in the body fluid surrounding the cell.

<h3>What is a hypotonic solution?</h3>
  • A solution having lower osmotic pressure than the solution to which it is compared.
  • It has lower amount of solute (high amount of solvent) compared to other solution separated by a semi-permeable membrane.
  • After consuming excessive amounts of pure water, the body fluid becomes hypotonic, so water enters from body fluid to the cell resulting in the cell to swell or break.
