Document Summary
Hypertension: potassium + sodium = high blood pressure. Deficiency is rare leads to blood pressure, salt sensitivity, kidney stones, and bone turnover. As with sodium, the kidneys can adjust the amount of potassium in the body by controlling the rate at which its reabsorbed or excreted. Toxicity usually from supplements or treatments: not due to food, thus no ul set, due to certain diseases or medications. Associated with sodium outside of the cell and potassium inside the cell. Involved in fluid and electrolyte balance: moves passively through membrane channels. Abundant in foods, consumed as part of salt. Deficiency is rare (usually from vomiting), as is toxicity. 2nd most abundant mineral in the body: found inside the cell with k, electrical neutrality, 85% in bones. Phosphate (po4 3-) in our body tissues. Other roles: part of dna, rna, lipid bilayer and lipoproteins, atp, regulates enzymes. Regulation of fluid balance: two factors, control of electrolyte balance, control of water balance.
