Solution to Frame 7
The first type of fluid we shall discuss is the intracellular
fluid (ICF), that fluid which is contained inside the body
cells. Intracellular fluid composes approximately two-
Intracellular fluid (ICF)
thirds of a person's total body water and approximately 50
percent of the person's body weight.
Extracellular fluid (ECF)
The intracellular fluid serves several functions. One, it
serves as a transporting medium in that it carries food and
oxygen into the cells and wastes and carbon dioxide from
the cells. The intracellular fluid also maintains the shape
and size of each cell in the body.
QUESTION: The intracellular fluid composes
approximately __________ percent of a person's body
Solution to Frame 10
The second type of body fluid is the extracellular fluid.
The extracellular fluid is located outside the body cells.
The intracellular fluid
The extracellular fluid (ECF) composes approximately
one-third of the water contained in the body and it
50% of a person's body
accounts for approximately 20 percent of a person's body
weight. The extracellular fluid also has several functions.
One, it carries nutrients and oxygen to the cells and waste
materials from the cells. Also, it serves to bathe the cells
in order to keep the cells moist.
