Study Notes

Water Composition and Role

Water comprises about 60% of an adult's body weight.
Essential for chemical reactions, body temperature regulation, blood volume maintenance, and lubrication.
Functions as a solvent and transport medium in the body.

Electrolytes Overview

Electrolytes are electrically charged minerals including sodium, chloride, potassium, calcium, phosphate, and magnesium.
Crucial for water distribution, conducting electrical charges in cells, muscle contraction, and hydration balance.

Functions of Water

Transportation: Known as the "universal solvent," enables substance dissolution for transport in blood, urine, saliva, and other fluids.
Chemical Reactions: Acts as an ideal medium with a stable pH of 7.0; essential for metabolic reactions.
Lubrication and Shock Absorption: Provides cushioning for joints, eyes, brain, and spinal cord, protecting against sudden changes.
Temperature Regulation: Maintains body temperature (set at 98.6°F or 37°C) by regulating water movement and heat distribution.

Importance of Electrolyte Balance

Water in the body contains electrolytes that regulate fluid movement within and outside of cells.
Key electrolytes include sodium, chloride, potassium, calcium, phosphate, and magnesium.

Sodium

Primary regulator of water balance; involved in nerve transmission, muscle contraction, and nutrient absorption.
Kidneys manage sodium levels; excess can lead to hypertension.

Chlorine

Maintains fluid balance and neutrality; aids in pancreatic juice flow and mucus production.
Found in foods like tomatoes, lettuce, and can be sourced from table salt.

Potassium

Most abundant cation inside cells; crucial for fluid balance, kidney function, muscle contraction, and nerve transmission.
Rich sources include fruits (bananas, avocados) and vegetables (potatoes, leafy greens).

Calcium

Vital for stable blood pressure, skeletal muscle contraction, and building strong bones and teeth.

Phosphate

Managed by kidneys, bones, and intestines; important for various biological functions and interacts closely with calcium.

Magnesium

Regulates muscle contraction, heart rhythm, and nerve functions; a crucial mineral for overall health.

Health Implications of Water and Electrolyte Imbalance

Overhydration: Excessive water intake can dilute electrolytes, impair bodily functions, and potentially cause death.
Dehydration: Common and dangerous, leading to severe health issues, including diarrhea-induced deaths and increased risks for kidney stones and heat-related illnesses.

Conclusion

Regular water suffices for general hydration needs, although electrolyte water may be beneficial in specific situations.
