DehydrationCurrent Lecture:Water:- H2O made of 2 hydrogen atoms and 1 oxygen atom - Needs no digestion and is easily absorbed- We don’t have to break it down into a monomer, it is just absorbed - Makes up 50 to 75% of body weight- Mostly you- Major solvent- Stuff dissolves in it easily - All of the sugars and salts and electrolytes can go into the blood- Very essential without water, death can occur within 1-2 weeks - Sweating a lot, can die in 1-2 days - Functions of water in the bodyThese 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.Functions of Water: - transports substances blood- your body puts out heat via sweat- what makes you not lose heat, and you have a bunch of sweat, and your put a fan onit cools down the body - if your body has a lot of water it is doing the most critical things Sources of Water: 1. Tap water: Hard water contains a variety of minerals, including calcium, sulfur, copper, iron and zinc- Most public water supplies provide fluoride - Added to the water in cities and towns- In boulder water- East coast say yes to fluoride and west say no- Cuts down on childhood cavities- Total water intake- Includes water in beverages and foods- Water weight of fruits and vegetables typically ranges from 60 to 95% 2. Metabolic water: Water formed by cells as a metabolic by product- Forming water by breaking down food - Bottled water - 1/3 of bottle water is actually tap water - not regulated very well- its what people like because it comes from different parts of the world- high carbon foot print The Essential Balancing Act:- Body water is lost through- Urine, perspiration, exhaled air, feces, perspiration, sweating- Your body is constantly loosing water- Mostly because you lose it from your skin- For your skin to be able to breathe you have a ton of water lose all the time- But your body needs water to function Daily Water Balance- Urine output is best indicator of adequate fluid water intake - Metabolic water food  drink- Urine that has a strong smell - 3-4 times a day of urination, your body is holding onto it.What is Diuretics?o Diuretics Substances that increase urine output- Two common dietary diuretics:o 1) Caffeine in coffee tea energy drinks and caffeinated soft drinks 8 oz in a cup of coffee, you will urinate 12 oz net lose of water by drinking these thingso 2) Alcohol in beer, wine, and spirits  when your hangover you drink water to get the water back that you lost Dehydration: People at risk for dehydration- Older adultso Do not sense thirst as quickly as younger people The elderly don’t feel thirsty anymore  Their sensors don’t tell them to drink - Sick peopledo Especially sick children with fever, vomiting, diarrhea Not a lot of surface area- Athletes and people who work or exercise outdoors in hot weather or in cold high altitude environments o Skiing high altitude Can too much water be toxic?- Water intoxicationo Too much water consumes at a time or conditions in which kidneys have difficulty filtering water from blood Excess water dilutes sodium concentration of blood disrupting water balance If you drink 4 gallons of water over the next 8 hours, your fine But if you drink 4 gallons over the next 20 minutes, you can die Your heart runs because you have a certain sugar and salt combination Over whelm the heart till it stops Because the water has diluted the salts and sugars that make the heart warm  Lots of water in a short amount of time is what kills you Signs and symptoms o Dizziness, headache, confusion, poor coordination, bizarre behavior and seizures  Bizarre behavior is like not wanting to hang out what your friends
