Q

Role of the kidneys

A

Removes waste products from the blood. Controls many nutrients (glucose, amino acids, water) in the blood. Removes waste products from the blood and along with the liver controls amount of many nutrients in the blood. They can either move metabolic and products, unnecessary substances absorbed from the gastrointestinal tract and potentially harmful compounds that have been detoxified by the liver

Q

Carbohydrate metabolism

A

Liver closely monitors glucose level. Insulin for modes uptake of glucose by all cells in the body, enabling them to catabolize and or store it. Deliver and skeletal muscles store glucose for glycogen. If the glucose levels fall below the step point level, hormones such as a glucagon promote the release of glucose from storage in the bloodstream.

Q

Ketones

A

Acidic metabolic products that are formed when an excessive amount of fat are oxidized for energy. They are not oxidized in the liver, but carried to the skeletal and cardiac muscles, we’re under normal circumstances, they are rapidly metabolized

Q

Alcohol metabolism

A

Supplies kilocalories for the body to use for energy. Metabolized by the liver. When alcohol is present, it is oxidized instead of that. This can cause lipid accumulation in the liver. In addition to liver damage, alcohol can interfere with the transport, activation, and catabolism of almost every nutrient.

25
Type one diabetes – insulin dependent diabetes
Defined as an autoimmune destruction of the beta cells of the pancreas, causing total insulin deficiency. Only 10% of diagnosed cases, commonly occur before age 30. Treated through diet, home blood glucose monitoring, and daily insulin injections
26
Type two diabetes – non-insulin dependent diabetes
Body produces insufficient amount of insulin or the body cells ignore the insulin and feel to use it to bring glucose into the body cells. Most common form and usually occurs after age 40. Treatment through diet, home glucose monitoring, medication or insulin injections
27
Fat soluble vitamins
A, D, E, K
28

Maintains normal extra cellular fluid concentration. Regulates acid – base balance. Facilitates impulse transmission in nerve and muscle fibers
48
Potassium
Maintains intercellular fluid concentration
49
What is the number one provider of energy
Carbohydrates. They are the first thing to break down.
50
What is the source of energy for the body
ATP. You get that by breaking down carbohydrates lipids and proteins
51
What component is needed for the development of collagen and nervous tissues
Carbohydrate
52
What is second to be broken down for energy if carbs are not available
Lipids
53
Lipids
Concentrated source of energy. Spears proteins.
54
What is the last thing to be broken down for energy
Proteins. This is bad because it releases nitrogen into your system and poisons you
55
Primary deficiency
Occurs when a person doesn't get enough of a certain vital nutrients, not eating enough of it
56
Secondary deficiency
Occurs when your bodies ability to absorb nutrients is limited by conditioner illness. You were eating enough of it but your body can't absorb it and use it
57
Tertiary deficiency.
One deficiency causes another deficiency, common with the B vitamins
58
Anabolism
Using absorb nutrients to build or synthesize more complex compounds. Process requires energy to build substances that make up the body itself and other substances necessary for body functions
59
What nutrient maintains blood glucose levels if consumed only one time a day
Carbohydrates. Carbohydrates will cause blood glucose to rise the most in the most quickly. Lipids I contain carbohydrates – like milk and juice – will cause blood glucose to rise faster than solids that contain carbohydrates – like bread –. Because of the impact that they have a blood glucose levels, carbohydrates are the most important macro nutrient for people with diabetes to monitor
60
Calcium and phosphorus relationship
If calcium level goes up, phosphorus level goes down – inversely related. Ideal calcium/phosphorus ratio for adults is 1:1. A protective mechanism is to prevent hi combined concentrations, which can lead to a calcification of soft tissues in stone formation
61
Iron deficiency anemia
#1 nutrient deficiency: obesity, in adequate dietary intake. The most prominent oral signs of iron deficiency include: Pallor of the lips, and oral mucosa, angular cheilitis, atrophy of filiform papillae and glossitis

66
Iodine
Production of thyroxine. Goiter
67
Thirst
In healthy adults, thirst is often an early sign of the bodies need for fluids but can often be mistaken for hunger.
68
How is water lost
Your nation. Perspiration. Expiration. Defection.
69
What happens when too much body water is lost
When 2% of body water is lost, osmoreceptors are stimulated creating a physiological desire to ingest liquids.
70
Osmoreceptors
Neurons in the hypothalamus that are sensitive to change in serum and osmolality levels. Stimulation of them causes thirst. They also increase the release of antidiuretic hormone from the pituitary gland. This causes body to retain fluids by decreasing urinary output
71
Osmosis
The movement of water from an area of low solute concentration to one of the higher solute concentration. Osmotic pressure within the body equalizes the solute concentration of intracellular and extracellular by shifting small amounts of water in the direction of higher concentration of solute
