Document Summary
*for exam know 2 functions, 1 symptoms of deficienty, 1 symptoms of toxicity, Sodium, potassium, calcium, phosphorus, magnesium, iron, zinc, iodine, and fluoride. 60% body weight = water: 2/3rd water extracellular, 1/3rd water intracellular, water distribution depends on solutes (concentration of dissolved substances like sodium, protein, potassium) Imbalanced solute concentration > osmosis (water diffusion) > direction that equalizes solutes. Water = slightly +ve and slightly ve pole. Water moved by blood pressure (forces water from capillary > space b/w cells/surround tissues) Factors that control blood pressure: kidney: regulate water loss in urine (controls blood pressure, vasoconstriction: signaled by brain for vessels to constrict to increase blood pressure, thirst. Factors that control blood pressure controled by hormones: antidiuretic hormone (adh): released by brain (pituitary gland) Solvent: dissolves nutrients/vits/minerals for body to use. Transporter: makes up blood > delivers o2 and nutrients > delivers waste to lungs/kidneys.
