Two types of cellular water

A

Intracellular fluid, extracellular fluid

28
Q

Intracellular fluid

A

Fluid found within the cell

29
Q

Extracellular fluid

A

Fluid found outside of the cell

30
Q

Types of extracellular fluid

A

Interstitial fluid and blood plasma

31
Q

Interstitial fluid

A

Fluid surrounding cells throughout the body

32
Q

Blood plasma

A

Fluid suspending blood cells

33
Q

Factors that affect bodily fluid
