potassium & phosphate

3

where is intracellular fluid located

inside the cell

4

what is extracellular fluid

Fluid outside the cells, about 1/3 of body water

5

what is interstitial fluid

Fluid between cells, usually high in sodium & chloride

6

what are the functions of water

1. Carries nutrients & waste products throughout body
2. Maintains the structure of large molecules such as proteins & glycogen
3. Participates in metabolic reactions
4. Serves as the solvent for minerals, vitamins, amino acids, glucose & many other small molecules so that they can participate in metabolic activities
5. Maintains blood volume
6. Acts as a lubricant & cushion around joint & inside the eyes, spinal cord, &, in pregnancy, the amniotic sac surrounding the fetus in the womb

28

how do fluids influence blood pressure

fluids maintain blood volume

29

what do the kidneys do

make urine, ridding waste and reabsorbing required substances
