Question | Answer |
Why is water essential | must be consumed for survival, blood is 90% water |
Polar bodies of water | H is(+) and O is (-) |
Function of Water | lubricates, cleanses, regulates body temperature, metabolic reactions such as condensation and hydrolysis, maintains acid base balance. |
High arteriole pressure | pushes water out of capillaries into the tissues |
Low venous pressure | brings water back into the capillaries from tissues |
Thirst mechanism- 1st sign | brain detects decrease in volume and increase of concentration of dissolved substances in blood. |
Thirst mechanism-2nd sign | Dry mouth = no water for saliva |
Thirst mechanism- 3rd sign | Dry mouth + brain = tells person to drink |
Thirst mechanism- 4th sign | Person drinks, increases blood volume and decreases concentration of dissolved substances. |
What gland releases ADH? | pituitary gland |
How does ADH function? | decrease blood vol and increase concentration vol ADH signals kidneys to absorb MORE water, less water lost in urine. ANTI-DIURETIC=(holding onto water) |
Symptoms of dehydration | fastest nutrient deficiency 1-2% = weight loss, heachache, fatigue, loss of appetite, dry eyes/mouth dark urine 5%= nausea & difficulty concentrating 7%= confusion, disorientation 10-20% = death |
How many liters do men need? | 3.7 |
How many liters to women need? | 2.7 |
Factors to increase water intake | weather, activity level, environment temp, humidity, diet |
Electrolytes | Sodium, Potassium, and Chloride |
Function of electrolytes | affects water distribution within the body, are essential to life, they are positive and negative need a proper balance |
Functions of the Sodium Potassium Pump | Active Transport System, maintains concentration gradient = nerve conduction and muscle contraction |
Where are electrolytes regulated? | Kidneys |
What can cause deficiency in electrolytes? | fluid loss and medications |
What are causes of electrolyte toxicity? | Renal failure & potassium supplements |
Why is sodium toxicity rare? | Fluid is usually increased to compensate |
What is hypertension | increase of blood pressure against the arterial wall |
Sources of water | drinking water, drinking other beverages, and wet foods |
functions of water | solvant, reactant, protector, transporter, regulates body temp and PH |
Effects of a water deficiency... | dk urine, weakness, low endurance, confusion, and disorientation |
groups @ risk of water deficiency | infants, people with fever, vomiting & diarrhea, elderly, athletes |
What can occur with a water toxicity... | confusion, coma, convulsions |
Is there an UL for H2O? | N/A |
Sources of sodium | Table salt, processed food |
What is affected with a Sodium deficiency?........ (Hint: pump) | MAJOR!!! (+) extracellular ions, nerve transmission, muscle contractions, fluid balance. |
Groups @ risk of sodium deficiency | severely restricted sodium diet, sweating excessively |
Toxicity of sodium | High blood Pressure |
Is there an Upper Level Intake of Sodium? | Yes! 2300 mg /day |
Sources of Potassium | fruits and veggies, legumes, whole grains, milk, meat |
Function of Potassium | (+) intracellular ion, nerve transmission, muscle contraction, fluid balance |
Deficiency of Potassium | Irregular heart beat, fatigue, muscle cramps |
Groups @ risk of Potassium | Poor diets high in processed foods, people w/ diarrhea and vomiting, those taking thiazole diuretics |
Toxicity | Abnormal heartbeat |
Upper level Intake of Potassium | N/A |
Sources of Chloride | table salt & processed foods |
Functions of Chloride | MAJOR!!! (-) extracellular ions, fluid balance |
Deficiency of Chloride | Unlikely |
Groups @ risk for Chloride Deficiency | None |
Toxicity to Chloride | N/A |
Upper Intake Level for Chloride | 3600 mg/day |
