BMI formula
703 x lbs/in^2
Protein (catabolism) uses:
Proteolysist, Deamination, and Transamination
In lack of 02, what is made
Lactic acid
If there is a high plasma pyruvate, it means
Vita B deficient
Protein (Anabolism)
1. Gluconeogensis
- AA to glucose
When the extracellular water increases in relation to intracellular water; may indicate
1.
2.
- Acute inflammation (body sends additional flow to area)
2. Renal disease (High sodium is in kidneys, and extracellular levels can increase edema)
Bile is produced in LIVER and store in Gallbladder; but when gallbladder is diseased, bile is secreted into
doudenum
Anabolism (4)
- what does it do
- requires or releases?
- Examples
- hormones
- Builder
- Requires energy
- ex: gluconeogenesis
- growth hormone, testosterone and estrogen
Catabolism (4)
- what does it do
- requires or releases?
- Examples
- hormones
- Breaks down
- Releases energy
- Ex: Glycolysis
- adrenaline, cortisol and glucagon
Diffusion
Particles moves from high to low
Ascites
Edema in the abdomen (b/c liver damage)
Alcohol is absorbed and digested where?
- absorbed in the stomach and small intestine
2. Digested in liver
Metabolic Acidosis
- What is it
- What caused it
- Compensation
- When the body has too much acid and kidneys cant remove it
- Seen in DKA w/ type 1 diabetes
- Increases in respiration to excrete C02 (HYPERVENTILATION)
Metabolic Alkalosis
- What is it
- What caused it
- Compensation
- Too many alkali producing bicarbonate
- Retention of base, vomiting and dehydration
- Decrease in respiration to retain C02 (hypoventilation)
Eating Omega 3 instead of High CHO?
Will lower Triglycerides
Winterized Oils
- Clear or cloudy
- 3 examples
Clear not cloudy
- corn
- soy
- cottonseed oil
Insulin hormone
- Produced
- Becomes active when
- stimulates
- inhibits
- By beta cells of the pancreas (decreases glucose levels)
- Becomes active when BG is HIGH
- The uptake of glucose and AA into the cells (the synthesis of glycogen by increasing glucose uptake by the liver)
- Gluconeogensis
When you eat omega 6 instead of CHO?
Lower LDL, and increase HDL
Cori-Cycle
when lactic acid goes to pyruvic acid
If a pt is over-feed..
it will increase RQ and lipogenesis
Elderly are low in ___ and often ___
- low in Fe and Calcium (d/t decreased absorption)
2. Constipated (d/t lower gastric motility)
