Fluid and Electrolyte Balance Concepts

This video tutorial covers the distribution and movement of body fluids, focusing on extracellular and intracellular compartments. It explains fluid intake and output, emphasizing passive movement through osmotic gradients. The video also discusses key electrolytes like sodium, potassium, calcium, and chloride, highlighting their roles in maintaining fluid balance and potential health impacts of imbalances.

What percentage of total body weight does water account for in an adult male?

• 40%

• 50%

• 60%

• 70%

How is the total body water distributed in terms of fluid compartments?

• All in ICF

• Two-thirds in ECF, one-third in ICF

• One-third in ECF, two-thirds in ICF

• Half in ECF, half in ICF

What is the primary route for fluid input in the body?

• Intravenous fluids

• Skin absorption

• Gastrointestinal tract

• Respiratory tract

How does water move between fluid compartments in the body?

• Actively using energy

• Passively through osmotic gradients

• Via active transport channels

• Only through blood vessels

Which system helps in correcting fluid accumulation in the interstitial space?

• Respiratory system

• Digestive system

• Nervous system

• Lymphatic system

Which electrolyte is primarily found in the extracellular fluid?

• Phosphorus

• Sodium

• Potassium

What mechanism do sodium and potassium use to move across cell membranes?

• Facilitated diffusion

• Osmosis

• Sodium-potassium pump

• Simple diffusion

What is the main anion in the intracellular fluid?

• Sulfate

• Chloride

• Phosphate

• Bicarbonate

Why is it important to maintain proper electrolyte levels in the body?

• To ensure proper digestion
