It's understood that tears are made to be isotonic to the cells it's traveling by when excreted by glands in the eye. This is to prevent swelling of the cells of the eyes if you start tearing up. Swelling could cause temporary impaired sight. Salt in our tears also is good for healing our selves and for killing bacteria around our eyes.

3 types of tonicity on a cell?
The three type are hypertonic, isotonic, and hypotonic. Hypertonic is when the tonicity of the cell is lower than that of the surrounding liquid, isotonic is when the tonicity of the cell is equal to that of the surrounding liquid, and hypotonic is when the tonicity of the cell is greater than that of the surrounding liquid.
What is a measure of a solutions ability to change the volume of cells by altering their water content?
tonicity
What type of tonicity will draw water from red blood cells or Elodea cells?
Salt/Salt Water
What is relative tonicity?
From NorthSeattle.edu (see link to the left):Tonicity1. Tonicity of aqueous solutions (water with solutes, such as salt, dissolved in it) is based on cellular responses to that solution.2. Solutions are isotonic if the cells or tissue neither shrink nor swell in response to immersion in that solution.3. Solutions are hypertonic if the cells or tissue shrink in response to immersion.4. Solutions are hypotonic if the cells or tissue swell in response to immersion.See the Web Links to the left for more information.
Why do you have tears?
we have tears to show are fellings and, to show people how we fell.
What is the tonicity of normal saline compared to your blood?
What is the tonicity of you blood
How does tonicity relate to osmosis?
Tonicity refers to the measure of the effective osmotic pressure gradient between two solutions. The higher the difference in the tonicity between the two solutions, the more osmosis transpires.
What are health related words that start with T?
Tonicity
Ethanol and animal cell tonicity?

Why do you use saline water when preparing a plate with blood agar?
TONICITY
What are the real world applications of tonicity?
Tonicity is a measure of the effective osmotic pressure gradient; the water potential of two solutions separated by a semipermeable cell membrane. In other words, tonicity is the relative concentration of solutes dissolved in solution which determine the direction and extent of diffusion. It is commonly used when describing the response of cells immersed in an external solution.
What role does the cell wall play in tonicity?
gives shape to plant cells
Do muscles maintain posture by the property of tonicity?
Yes, if you contract the right muscles.
What is the difference between osmolarity and tonicity?
Tonicity refers to the relative concentration of solute particles inside a cell, with respect to the concentration outside the cell. Osmolarity refers to the movement of water from the inside to the outside of a cell, and vice versa

What is the concentration of material in a cell that affects the fluid volume and pressure within the cell?
