HES 2823 1st Edition Lecture 24 Outline of Last Lecture I Minerals A Iron B Iodine C Fluoride Outline of Current Lecture I Water A Functions B Intracellular C Extracellular D Electrolytes E Fluid Balance F Recommendations G Deficiency Current Lecture I Water A Functions 1 Medium of the cell 2 Transport in blood which is primarily water 3 Dissipate heat through sweat B Intracellular inside the cell 50 of water in the body C Extracellular outside the cell blood interstitial fluid cerebral spinal fluid eyeballs 50 of water in the body D Electrolytes minerals 1 Sodium Na found primarily in extracellular fluid 2 Potassium K found primarily in intracellular fluid 3 Chloride Cl 4 Function a Nerve transmission E Fluid Balance 1 Sweating a Swear glands beneath the skin secrete table salt NaCl and water H2O to the surface of the skin which carry heat with them at they dissipate These notes represent a detailed interpretation of the professor s lecture GradeBuddy is best used as a supplement to your own notes not as a substitute b The sodium concentration in blood changes as sweating occurs as much water is lost and lesser amounts of sodium are lost altering the ratio c Blood becomes thicker as perspiration occurs d Sweating causes water to move out of the cell to balance the electrolyte concentration making the cell function less efficiently e As the body absorbs water in the gut it enters the blood stream and re enters water lacking cells F Recommendations 1 Drink water frequently a 1 pint of water 1 pound 2 Performance impaired at 2 weight loss but thirst does not occur until a 2 loss 3 Preventing hyponatremia water intoxication low sodium levels in the blood a Life threatening brain swelling b Blood diluted so that water moves into higher concentrations of electrolytes in cells c Drinking too much water compared to sodium intake causes this d Gatorade intended to replace lost electrolytes in sweat 4 Potassium a Small amounts lost in sweat but most remains in cell b Food sources Bananas and oranges G Deficiency dehydration 1 Heat stroke not enough water for the production of sweat 2 Cramping tendencies a Crampers heavy sweaters producing large volumes of sweat and a high concentration of sodium in that sweat i Suggests need for more sodium than usual 3 Vomiting a Loss of water and chloride 4 Diarrhea a Loss of water and sodium b Pedialite salt water for infants to replenish electrolytes under these conditions
