What is the relationship between intracellular and extracellular fluid?
Interdependent and closely linked
What is the primary function of the distribution of body fluid?
Supporting cellular functions
What happens to cells when they are placed in a hypertonic solution?
They shrink due to water leaving the cell
What is the purpose of fluid movement in a hypertonic solution?
To create an equilibrium
What would be the result of placing a cell in a hypertonic solution with a higher solute concentration?
The cell would shrink due to increased water loss
What drives the fluid movement in a hypertonic solution?
Osmosis
What is the result of the fluid movement in a hypertonic solution on the cell membrane?
The cell membrane becomes less permeable
Study Notes
Factors Affecting Body Fluid, Electrolyte, and Acid-Base Balance
- Age is a factor that affects body fluid, electrolyte, and acid-base balance, as elderly people have a blunted thirst response.
Importance of Water in the Body
- Water plays a crucial role as a transport mechanism for nutrients, waste products, and other substances.
- Water acts as a lubricant in the body.
Distribution of Body Fluid
- The body fluid is divided into two major components: intracellular fluid and extracellular fluid.
Types of Solutions
- Normal saline solution is a type of solution with a concentration of 0.9% NaCl.
- Hypertonic solution: a solution with a higher solute concentration, causing cells to shrink as fluid is drawn out to create balance.
- Hypotonic solution: a solution with a lower solute concentration, causing cells to swell as fluid is drawn in to create balance.
This quiz covers the factors that influence body fluid, electrolyte, and acid base balance, including age-related effects. Learn how different factors impact the body's balance and how to maintain optimal balance.
