PLAY
breakup of large lipid droplets
emulsification
Disease where very little insulin is produced by the pancreas
Diabetes
Amount of fluid that enters the nephron per unit time
GFR
Food is entering the blood from the digestive tract.
Absorptive State
The change from glucose catabolism to fat utilization as major energy
Glucose-Sparing
Lipoproteins formed in the intestine to carry lipids into circulation
Chylomicron
Lipoproteins formed in the liver to carry cholesterol to peripheral tissues
LDL
Produce Gastrin
G Cells
Produce Insulin
Beta Cells
Produce stomach acid and intrinsic factor
Parietal Cells
Produce pepsinogen
Chief Cells
Produce Glucagon
Alpha Cells
Produce rennin and regulates GFR
Juxtaglomerular
Hormone secreted by the digestive tract which acts to stimulate hunger
MSH
Hormone secreted by "full" adipose cells which acts to decrease hunger.
Leptin
The process by which the surface of a microorganism is covered with antibodies and complement, rendering it more likely to be phagocytized.
Opsonization
Glucose- dependent insulinotropic peptide (GIP) is stimulated by fasting
FALSE
Glucose is the main energy source in the post-absorptive state
FALSE
The hormone which is stimulated by the presence of acid in the small intestine, whose actions include inhibiting stomach acid secretion, which stimulating bicarbonate production is known as Gastrin
FALSE
Unlike the other digestive enzymes, carbohydrate-digestive enzymes are secreted as inactive forms know as zymogens, in order to protect the secreting cell from self digestion.
FALSE
The liver, gall bladder and pancreas are known as accessory digestive organs.
TRUE
Suppressor T cells are lymphocytes that attack foreign cells or body cells infected with viruses.
TRUE
The hormone vasopressin/ADH stimulates the kidneys to retain sodium ions.
FALSE
. Macula Densa cells in the nephron secrete rennin.
FALSE
Atrial natriuretic peptide ANP increases the GFR.
TRUE
Though often overlooked, the digestive system plays important roles in protecting the body from viruses and bacteria.
TRUE
The pancreas secretes a fluid rich in bicarbonate in response to the hormone motilin.
FALSE
Acid is formed in the stomach by "Splitting" H20 into H+ and OH-, then combining the OH- with CO2 to form HCO3.
TRUE
The single most important hormone determinant of basal metabolic rate BMR is.....
Thyroid hormone
GFR is more the RC
there is reabsorbtion
Lowdensity Lipoproteins and very low density lipoproteins......
Cannot penetrate the capillary walls, so must have 2 fatty acid enzymatically broken off and enter adipose cells.
29. Glucagon.....
Stimulates gluconeogenesis
30. Carbohydrates are broken down by the enzymes know as....
Amylases
Anorexia Nervosa
The restriction of food intake due to the fear of gaining weight
The nutrients that yield the most energy per gram when metabolized are....
Fats
The portion of the nephron which is responsible for the secretion of products into the filtrate is..
Distal convoluted tubule
The hormone primarily responsible for increasing cellular uptake of glucose from the blood..
Insulin
. Mucus functions in...
BOTH A AND B
. Antibodies are proteins secreted by...
Plasma cells
Increased parasympathetic stimulation of the intestine would result in...
None of the ABOve
Antigen presentation is a primary function of which cell??
Macrophages, B-Cells, and dendritic cells
The principal antibody in circulation, it attacks microorganisms and their toxins is called..
IgG
Which of these is described incorrectly??
Actively acquired immunity- immunity passed via the placenta or milk to offspring
Atkins Diet
Smell the aceto acetate breath because of ketones
Normal level of LDL elevated HDL
Don't change life style.. High levels are good because it may lower your risk of developing heart disease. b/c HDL helps remove fat by binding with it in the bloodstream and carrying it back to the liver for excretion in the bile and disposal
regular exercise helps with NIDDM control blood glucose levels?
exercising improves your body's use of insulin, and insulin stimulates the liver and muscles to take in excess glucose. This results in lower glucose levels
Hormone increases protein and lipid catabolism.. uptake of muscle and adipose tissues..
CORTISOL
If renal clearance of a substance is greater than the GFR of that substance what does that indicate about that substance in terms of kidney functions?
That there is a net secretion and not reabsorbation
Cholesterol high, removed from diet. Doctor accused you of cheating.
Nearly all cells in the body can synthesize cholesterol even without food. So even on a no chelosterol diet, the cells in your body may still produce high cholesterol numbers just by making it themselves.
GFR in kidney is controlled by altering BP in glomular capp..how without changing whole body bp.
The efferent arteriole dams up not allowing B.P outside of the glomerulus to effect the rest of the body.
Gastric Banding... Eat several small meals... ate big meal, passed out, why/
Because of the gastic dumping (undigested food into SI) that started absorbing too much of his bodies water causing( decrease in blood volume, low blood pressure, decreased oxygen to brain casing wooziness and fainting). Heart and brain not enough blood and oxygen.
Simple sugars like fruits and stay hydrated and keep
electrolytes balanced.
Ingested a macromolecule which strongly triggers the secretion of CCK.. what have you ingested?
LIPID..Fat
