Types of Body Fluids Quiz

Fluid Compartments

• The intracellular fluid compartment contains the total fluid content of all cells in the body.
• Cerebrospinal fluid is typically found in the central nervous system, surrounding the brain and spinal cord.
• Transcellular fluid is a type of fluid that is not found in the interstitial fluid compartment; examples include cerebrospinal fluid, synovial fluid, and aqueous humor.

Collagen Fibers

• Collagen fibers are typically found within the interstitial fluid compartment of the body.

Blood Plasma

• The vascular fluid compartment includes the blood plasma within the closed system of heart and veins.

Epithelial Fluid

• Epithelial fluid is a type of fluid found at various parts of the body, laid with epithelial cells; examples include saliva, sweat, and digestive fluids.

Fluid Balance and Electrolytes

• Hyponatremia is a condition characterized by sodium depletion, the reverse of hypervolemia.
• Dehydration is often synonymous with hypovolemia, caused by a relative deficit of free water in the body.
• Sodium, potassium, and calcium are the main ions important for electrolyte distribution.
• Hypernatremia is a condition involving water excess relative to the sodium in the body, making it synonymous with dehydration.
• Hypovolemia is usually treated by fluid replacement.

Body Water Content

• The approximate total body water for a 70 kg man is 42 liters.
• The interstitial fluid compartment is not explicitly mentioned in the text.
• Extracellular Fluid (ECF) approximately accounts for 20% of Total Body Water (TBW).
• The plasma fluid compartment is stated to be about 3.2 L in volume.
• The body is approximately 55-60% water.

Other Fluid-Related Topics

• Interstitial fluid is categorized as part of Extravascular Fluid.
• An equivalent is formally defined as one mole of an electrolyte that can combine with one mole of hydrogen or hydroxyl ions.
• Maintaining balance between intracellular and extracellular ion concentrations is important to prevent muscle cramps, weakness, and nerve problems.
• Calcium contributes to muscle contraction by binding to troponin and tropomyosin, exposing the actin-myosin binding site.
• Sodium and potassium play a crucial role in nerve response by generating action potentials.
• Maintaining fluid balance is critical to prevent dehydration, hypovolemia, and electrolyte imbalances.
• When calcium leaves the muscle cells, muscle contraction ceases.
• Synovial fluid lubricates the joints.
• Amniotic fluid protects the fetus.
• The mechanism of thirst is triggered by the hypothalamus in response to changes in blood osmolality.
• Most of the fluid loss of the body occurs through the kidneys.
• Increased fluid loss through perspiration is led by an increase in body temperature.
• Generation of metabolic water occurs under conditions of cellular respiration.
