Factors Affecting Fluid Balance

• Intake: Fluid intake is primarily through drinking water and other beverages, as well as from moisture in foods.
• Output: Fluid output occurs through processes such as urination, sweating, breathing, and bowel movements.
• Hormonal Regulation: Hormones such as antidiuretic hormone (ADH) and aldosterone play a crucial role in regulating fluid balance by controlling the reabsorption of water in the kidneys.

Importance of Fluid Balance

• Transport of Nutrients: Fluids help transport nutrients to cells and carry waste products away from cells.
• Regulation of Body Temperature: Sweating helps regulate body temperature by releasing heat when the body is too warm.
• Maintenance of Blood Pressure: Adequate fluid levels are necessary to maintain blood pressure and ensure proper circulation.
• Lubrication of Joints: Fluids in the body help lubricate joints, reducing friction and allowing for smooth movement.
