osmo: osmosis
regulation: to control
- the fluid that surrounds the cell, must be isotonic with the cytoplasm of the cells
- this means that the amount of the water going into and out to the cells is equal
-the cell will remain the same size shape and maintain the function
the danger to the tissue is that blood circulating into the tissue would be concentrated causing a hypotonic tissue fluid or it may be very dilute causing a hypotonic tissue fluid
-(hypotonic tissue-may remove too much water or add too much water)
- we want to keep the tissue fluid isotonic to the cell cytoplasm
= achieve by controlling the composition of blood
- blood forms the tissue fluid
--> role of kidney to control the composition of blood
- the blood which circulate through our kidney excess water, salt and can be remove and excreted to the ureter
= controlling the water and salt in the blood the kidney can keep the blood and the tissue fluid isotonic with the cells cytoplasm maintaining the
of the cells
