isotonic

Examples of isotonic in the following topics:

• Tonicity

  • Three terms—hypotonic, isotonic, and hypertonic—are used to relate the osmolarity of a cell to the osmolarity of the extracellular fluid that contains the cells .
  • In an isotonic solution, the extracellular fluid has the same osmolarity as the cell.
  • Blood cells and plant cells in hypertonic, isotonic, and hypotonic solutions take on characteristic appearances.
  • Cells in an isotonic solution retain their shape.
  • Osmotic pressure changes the shape of red blood cells in hypertonic, isotonic, and hypotonic solutions.

• Osmoregulators and Osmoconformers

  • Most marine invertebrates, on the other hand, may be isotonic with sea water (osmoconformers).
  • The shark's blood electrolyte composition is not similar to that of seawater, but maintains isotonicity with seawater by storing urea at high concentrations.

• Introduction to Osmoregulation

  • Isotonic cells have an equal concentration of solutes inside and outside the cell; this equalizes the osmotic pressure on either side of the semi-permeable membrane.
  • Response of red blood cells in hypertonic, hypotonic, and isotonic solutions
  • The blood maintains an isotonic environment so that cells neither shrink nor swell.

• Osmoregulation

  • There are three types of tonicity: hypotonic, hypertonic, and isotonic.
  • In an isotonic condition, the relative concentrations of solute and solvent are equal on both sides of the membrane.
  • Many marine invertebrates have internal salt levels matched to their environments, making them isotonic with the water in which they live.
