GEMP - Body Fluids and Its Compartments
Body Fluids and Its Compartments Introduction Body fluids are essential for maintaining homeostasis and facilitating various physiological processes. Understanding the compartments of body fluids is crucial for medical professionals as it influences fluid management, disease diagnosis, and treatment strategies. Key Concepts 1. Types of Body Fluids Body fluids are categorized into two prim...

Quiz Questions Preview
Question 1
What percentage of total body fluid does intracellular fluid (ICF) account for?
Explanation
Intracellular fluid (ICF) accounts for approximately two-thirds of total body fluid.
Question 2
Which component accounts for approximately 75% of extracellular fluid (ECF)?
Explanation
Interstitial fluid makes up about 75% of extracellular fluid (ECF).
Question 3
What is the normal range of plasma osmolarity?
Explanation
Normal plasma osmolarity ranges from 280 to 300 mOsm/L, which is crucial for fluid balance.
Question 4
Which process describes the movement of water across a semi-permeable membrane from an area of lower solute concentration?
Explanation
Osmosis is the process of water moving across a semi-permeable membrane from an area of lower solute concentration to one of higher concentration.
Question 5
What can cause edema in the body?
Explanation
Edema is often caused by increased hydrostatic pressure, which leads to excessive accumulation of interstitial fluid.
Question 6
Which factor does NOT influence fluid distribution in the body?
Explanation
While age, gender, and pathological conditions can influence fluid distribution, body temperature does not directly affect the distribution of body fluids.
Question 7
What type of solution can cause cells to swell due to an increase in osmotic pressure?
Explanation
A hypotonic solution has a lower concentration of solutes compared to the cells, leading to cellular swelling as water moves into the cells.
Question 8
Which of the following statements about body fluids is incorrect?
Explanation
The incorrect statement is that intercellular fluid is the same as extracellular fluid; in reality, they are distinctly different compartments.
Question 9
Which of the following does NOT describe a characteristic of transcellular fluid?
Explanation
Transcellular fluid does not account for the majority of total body fluid; it is a minor component compared to interstitial fluid and plasma.
