What does water do in the body?

Maintain component of cells; Necessary for growth and reproduction; Aids digestion; Helps deliver oxygen; Regulates temperature; Acts as shock absorber; Lubricates joints; Keeps membranes moist; Flushes body waste; Used to make hormones and neurotransmitters

Why is water crucial to survival?

Maintaining the right level of water in the body is crucial to survival

How does water leave the body?

Water leaves the body via kidneys, skin, lungs, and feces

Osmoregulation

Regulation of water in and outside the cell; Water moves across membrane to equalize concentrations of solutes

Hydration

The replacement of body fluids lost through sweating, exhaling, and eliminating waste

How much water does the body lose each day?

2-3 quarts of water

Excessive Hydration

Puts pressure on heart and causes edema (Fluid stuck in tissues)

Lack of Hydration

Dehydration

Hydration Balance

Balance of fluid is regulated by hormones; Balance between input and output should be 1:1

Electrolytes

Electrically charged minerals that cause physiological reaction, trying to maintain homeostasis; Keep the body hydrated; Regulated by kidneys and hormones

Sodium

Muscle Movement, Nerve Impulses, Blood Pressure

Potassium

Health Blood pH Level, Nerve Impulses and Muscle Contraction, Regulate Heartbeat

Chloride

Assists with intracellular and extracellular fluid balance in body; Aids in Digestion; Main Source - Table Salt
