skin persipitation lung respiration urine then feces are the way its excreted We lose about 2800 mL a day Regulation 0 The body Regulates blood volume and pressure to signal our body and say if it should retain water 0 The pituitary gland releases ADH that tells the kidneys to hold onto water Adrenal gland above kidney releases Aldosterone when they detect high blood pressure and tells the kidney to hold onto sodium Dehydration and Water toxicity Thirst mechanism is sometimes slow and unreliable Special populations 0 Water intoxication rare but potentially fatal hyponatremia Low Blood Sodium Clicker Questions 1 the majority of uid in body is where Intracellular this is 23rCI of the bodies uid The younger the age the higher the body water they have Men vs Women men have higher water Vitamis Basics Small amounts Organic Give no evergy MOST cannot be made by body Available in a variety of foods dairy is the only source that gives Vitamin D Vitamin 812 is only In animal based foods Fat Soluble don t like water Vitamins ADEK Dissolved in fats Stored in fat tissue and liver Higher potential for toxicity Water Soluble B Vitamins Vitamin C Found freely transported in blood because they get along with water Don t store these Excrete excessive amounts Not typically toxicity Frequently needed Digestion Begins in stomach Pancreatic enzymes released into Small Intestine Fat soluble vitamins need bile to help be absorbed Fat soluble vitamins also wont to be absorbed well if there s not fat in the body Fat Soluble vitamins go to the Lymphatic System before going into the blood Water soluble vitamins can go straight into blood after the Small Intestine The only Vitamin that gets 100 absorbed in the small intestine is Vitamin K Vitamin Status Severe De ciencies rare

than vitamins can be toxic in excess amounts Many Minerals act as Cofactors 0 Pretty much the same thing as coenzymes but for minerals Bioavailability of nutrients Amount of nutrients that is absorbed and available to the body Protects us from getting to much of a possibly dangerous nutrient In uenced by physiological needs amount consumed dietary choices binders calcium is only gained from dairy Mineral Status 0 Several de ciencies are rare 0 Most common iron and iodine 1 most likely to be toxic Vitamin D This is because its fat soluble 2 True or false minerals are more likely to be durable
