6:05 PM Minerals- naturally occurring, inorganic, homogeneous substances; chemical elements. Major minerals- essential mineral nutrients required in the adult diet in amounts greater than 100 milligrams per day. Also called macrominerals. Trace minerals- essential mineral nutrients required in the adult diet in amounts less than 100 milligrams per day. Also called microminerals. Water-The brain is composed of approximately 80% water. It makes up 60% of an adult person's weight. 80lbs of water in a 130lb person. Water carries nutrients throughout the body
Serves as the solvent for minerals ,vitamins, amino acids, glucose, and other small molecules
Cleanses the tissues and …show more content…
Water provide and the medium for transportation, acts as a solvent, participates in chemical reaction, provides lubrication and shock protection, and aids in temperature regulation in the human body. Solvent- a substance that dissloves another and hold it in solution.
Dialysis- a medical treatment for failing kidneys in which a person's blood is circulated through a machine that filters out toxins and wastes and returns cleansed blood to the body. Also called hemodialysis.
Water balance-the balance between water intake and water excretion, which keeps the body's water content constant.
Dehydration- loss of water.
Water intoxication- a dangerous dilution of the body's fluids resulting from excessive ingestion of plain water. Symptoms are headache, muscular weakness, lack of concentration, poor memory, and loss of appetite.
Water losses from the body necessitate intake equal to output to maintain balance. The brain and kidneys regulate water excretion. Dehydration and water intoxication can have a serious consequences. Water needs vary greatly depending on the foods a person eats, the air temperature, and himidity, the altitude, the person's activity level, and other …show more content…
Sodium attracts water. Sodium chloride is table salt. Too much dietary salt raises blood pressure and aggravates hypertension. Diets rarely lack sodium. Potassium maintains normal fluid and electrolyte balance; facilitates chemical reactions; support cell integrity; assists in nerve functioning and muscle contractions
Deficiency- Muscle weakness, paralysis, confusion
Toxicity- Muscle weakness; vomiting; vomiting
Food sources- orange juice, banana, avocado, baked potato Sulfate is the body's major negative ion. It's a necessary nutrient used to synthesize sulfur-containing body
