- 3The Main Nutrients are..1. Water
2. Carbohydrates
3. Protein
4. Lipids
5. Vitamins
6. Minerals - 4Water is the..cheapest, most abundant and essential nutriant
- 5Which nutriant deficancy will kill first?Water
- 6Who has the most total body water (TBW) on average?Infants
- 7Rank body water average77% - Infants
60% - Adult Males
50% - Adult females - 8Why do Males have a higher TBW than Females?Males typically have higher muscle percentage
- 9Water content in body tissuesMuscles - 75%
Adipose - 15%
Fresh bone - 30%
Tooth enamel - 5% - 10Which body tissue has the greatest amount of water content?Muscles
- 11What is Adipose?Fat
- 12What percentage of water loss will cause death?20%

- 17What percentage of water loss will cause Muscle spasms and delirium?10%
- 18Which nutriants are dry matter?Carbs
Protein
Lipids
Vitamins
Minerals - 19Which nutriants are inorganic?Minerals
- 20Which nutriants are called 'Ash'?Minerals
- 21Which nutriants are organic?carbs
protein
lipids
vitamins - 22Is water still in the body?No, it's turned over/recycled
- 23How often is water turned over?~ 3 days
- 24What are the main sources of water?1. Fresh drinking water
2. Water from food
3. Metabolic - 25How much water in intracellular? How much in interstital?66% ,
33% - 26Highest K+ concentration?Intracellular
- 27Highest Na+/Cl- ConsentrationExtracellular
- 28Is interstitial and extracellular the same thing?Yes
- 29Is water concentration heavily regulated intra- or extracellularly?Intercellularly, the body 'hates' salt
- 30CatabolismBreakdown/destruction
- 31AnabolismGrowth/ Building
- 32BioavailabiliyProportion of substabce that is absorbed into general circulation
- 33MineralsNa+, K+, Ca2+, Cl-, Mg2+
- 34What is Cytosol?The fluid in the cell (makes up Cytoplasm)
- 35What is the Cytosol made up of?Water
- 36What does Water do?1. Transports
2. Dictates Osmoality
3. Is apart of many rxn's
4. Lubricates and cushions joints
5. Gives cells shape
6. Apart of A/B regulation
7. Maintains body temp. - 37Human blood pH?~7.4
- 38Why does water have to be maintained between 7.35 - 7.45?Any lower will cause acidosis
Any higher will cause alkalosis - 39What is acidosis?Body fluids are too acidic
(Too little Biarbonate/Too much H+(acid)) - 40What is alkalosisBody fluids are too basic/alkaline
(Too much Bicarbonate/Too little H+(acid)) - 41Types of water loss?Sensible and Insensible
- 42Sensible water loss?Urine
Feces
Lactation - 43Insensible water lossLungs (vapor)
Skin (sweat) - 44Dietary factors that increase water intake1. More food
2. More protein
3. More salt
4. More indigestible fiber
5. Accessability - 45Why does fiber increase water intakeFiber absorbs water
- 46Environmental and phsycological factors that increase water intake1. Temp. Stress
2. Gestation/pregnancy
3. Lactation
4. Work
5. Age*
6. Disease
7. Species - 47How does age affect water intake?The older an animal gets, the less they need to drink due to lower maintainance requirements (less muscle = less water intake)
(Less bone = less water intake) - 48List species water intake per BW% from MOST to LEASTCaprine/Ovine (Dairy) > Bovine (dairy) > Bovine (Meat) > Caprine/Ovine (Meat) > Avian > Porcine > Equine
- 49List species water intake frequency from MOST to LEAST* [May be wrong don't feel like checking atm]Avian > Porcine > Equine > Caprine/Ovine > Bovine
- 50Are water quantity and quality important?Yes, changes in both change water consumption
- 51What effects water quality?1. Nitrates/ites
2. Fluoride
3. Heavy Metals
4. Ca, Mg, Na salts
5. Organic toxins
6. Pathogenic Organisms - 52What factors effect water quantity1. Facility
2. Envrionmental
3. Dietary restrictions/Deficiancies - 53What Facility factors effect water quantity?- Capacity
- Animal dominance/guarding
- Water flow rate - 54What Environmental factors effect water quantity?- Increase Heat
- Freezing temps.
-Drought
