Body fluids 2015 - 2016
 The fluids in our bodies are composed of water and dissolved substances,
including electrolytes, which are crucial for body function.
 We ingest water and electrolytes through the gastrointestinal or GI tract.
Movement of Fluids Through the Body
1. Absorption.
These fluids are absorbed into the plasma in the intestine.
2. Circulation.
The fluids circulate within the plasma, bathing the cells in the body.
3. Excretion.
The kidneys remove excess ions and water from the body through the urine,
although water is also lost at other sites, which will be described later.
Body fluids 2015 - 2016
1. Helps maintain body temperature.
When water vaporizes off the skin, it takes large quantities of heat with
it. This process cools the body temperature down.
2. Acts as a protective cushion in amniotic fluid
and cerebrospinal fluid.
3. Acts as a lubricant in the serous fluids, joints, and
gastrointestinal tract.
4. It is the reactant for hydrolysis reactions that occur
in the body.
5. Acts as a solvent to dissolve molecules and ions
in the body.
Body fluids 2015 - 2016
The percentage depends on the amount of fat tissue, which is only
about 20% water, compared to lean body mass or muscle mass
which is about 65% water.
 Newborns have the highest percentage of water in their bodies.
 A healthy young man who is muscular and does not have a lot of fat
in his body is about 60% water.
 A healthy young woman naturally has more fat and less muscle than
a man and is about 50% water.
 The more fat a person has in his or her body, the less water is
present.
 Older people tend to have less lean body mass and therefore contain
less water.

Body fluids 2015 - 2016
Water, along with its dissolved solutes, occupies two main
compartments within the body.
1. Intracellular fluid (ICF)

– Inside the cells (cytosol)
– 55% of total body water
2. Extracellular fluid
– Outside the cells
– 45% of total body water
Body fluids 2015 - 2016
1. Interstitial fluid
 Present between the cells
 Approximately 80% of ECF
3. Also includes
-
2. Plasma
 Present in blood
 Approximately 20% of ECF
