Body Fluid compartments

Question 1

How many types of compartments do we have in the body? Name them.

Answer 1

Two
They are ;
1. Intracellular fluid compartment - fluid inside the cell.
2.Extracellular fluid compartment- Fluids outside of the cell.

Question 2

Homeostasis

Answer 2

It’s simply called equilibrium.
For the body to function normally, there should be an equal amount of electrolytes and fluid at each compartments.

When an electrolyte inside a cell moves , another from the exterior has to come in the cell to fill the gab for homeostasis to take place.

Question 3

Semi Permeable Membranes

Answer 3

•They separate each body compartment from the other.

These are Cell membranes and Capillary Walls

As the name suggests, it doesn’t allow anything just to pass through it, it’s very selective with what it allows to pass through him

Question 4

Third spacing

Answer 4

This is simply caused by a disease or injury where there is an accumulation or sequestration of fluid that is trapped in an actual or potential body space.

When this happens , it means there is fluid volume loss.

Fluid can be trapped in the Percardial, pleural, abdominal, joint cavities, bowel etc.

Assessing a patient with INTRAVASCULAR FLUID THIRD SPACING is difficult because , it doesn’t manifest in changes in the body weight or intake and output balance . The only time it manifests is when there is an organ malfunction or failure.

Question 5

EDEMA

Answer 5

EDEMA is when there’s an accumulation of fluid in the interstitial space which is caused by problems from oncotic pressure, hydrostatic pressure, capillary permeability and lymphatic obstructions.

There are two types of EDEMA.

That is Localised EDEMA and generalised EDEMA .

As the name implies, localised EDEMA is confined to one place in the body and occurs from accidents , surgeries, local inflammatory processes or burns

Generalised EDEMA (Anarsaca) is an excessive accumulation of fluid in the interstitial spaces throughout the body which occurs as a result of cardiac, renal or liver conditions

Question 6

Function of body fluid

Answer 6

To transport Nutrients to the cells and carry waste products away from the cells .

Question 7

Amount of body fluids per body weight of each year group.

Answer 7

Infants - 80%
Young Adults - 60%
Older Adults - 55%

For this reason, it is importance to monitor infants and older adults for fluid imbalances and correct them promptly

Question 8

Body constituent that do not dissociate

Answer 8

1. Glucose
2. Urea
3. Creatinine
