Module 4 - Blood Glucose Agents, Vitamins & Minerals Flashcards
(175 cards)
What organ monitors glucose regulation?
Pancreas
What are the two glands included in the pancreas?
- Endocrine Gland
- Exocrine Gland
What is the endocrine gland responsible for?
Produces hormones in the islets of Langerhans
What is the exocrine gland responsible for?
- Releases sodium bicarbonate and pancreatic enzymes directly into the common bile duct to be released into the small intestine
- Neutralizes the acid chyme from the stomach and aids digestion
Define insulin
- Hormone produced by beta cells of the islets of Langerhans
- Released into circulation when levels of glucose around these cells rise
- Stimulates glycogen synthesis, conversion of lipids into fat stored as adipose tissue, and synthesis of proteins from amino acids
- Released after meals, causing glucose levels to fall
Define glucagon
-Released from alpha cells into islets of Langerhans in response to low blood glucose
2. Causes immediate mobilization of glycogen stored in the liver and raises blood glucose levels
Define adipocytes
- Secretes adiponectin
- increases insulin sensitivity
- decreases release of glucose from liver
- protects blood vessels from inflammation
Define endocannabinoid receptors
- Keep the body in a state of energy pain to prepare for stressful situations
Sympathetic nervous system function
- decreases insulin release
- increases release of stored glucose
- Increases fat breakdown
Corticosteroids function
- Decreases insulin sensitivity
- Increases glucose release
- Decreases protein building
Growth hormone function
- Decreases insulin sensitivity
- Increases FFAs
- Increases protein building
Hyperglycemia
Increased blood sugar
Glycosuria
Sugar is spilled into the urin
Polyuria
Increased urination
Polyphagia
Increased hunger
Polydipsia
Increased thirst
Lipolysis
Fat breakdown
Ketosis
Ketones cannot be removed effectively
Acidosis
Liver cannot remove all of the waste products
Characteristics of diabetes mellitus
- Complex disturbances in metabolism
- Affects carbohydrates, protein, and fat metabolism
Clinical signs of diabetes mellitus
- Hyperglycemia (fasting blood sugar level greater than 126 mg/dl)
-Glycosuria
Vascular damage
Occurs after long term results from diabetes mellitus
What are the disorders related to diabetes
- Atherosclerosis
- Retinopathy
- Neuropathies
- Nephropathy
- Infections
- Foot ulcers
Define atherosclerosis
- Heart attacks and strokes related to the development of atherosclerotic plaques in the vessel lining
