Exam 3: Homeostasis Flashcards
What is Homeostasis?
A stable internal internal environment that is ideal for cellular activity
What is an example of Homeostasis?
Thermoregulation
What are some cellular activities involved in Homeostasis?
oxygenation
acidity
temperature
salt and water
What is the desired set point for human homeostasis?
98.6 degrees
Redundancy outlines that:
Each system has multiple mechanisms for monitoring stores, conservation, obtaining new resources, and shedding the excess
What is Allostasis?
A system shift it responses depending on prior experience
What are the two types of Thirst? What are the difference between the two?
- Osmotic Thirst - water is drawn out of the cells because the concentration of salt in the extracellular fluid has increased
- Hypovolemic Thirst - Type of thirst due to vomiting or constant diarrhea where there is a change in volume
The taking in of food to supply the body with molecular building blocks and energy to survive and function properly?:
Eating
What is the formal definition of digestion?
The gastrointestinal process of breaking own food an absorbing it in to the body
What are the three energy forms that can be delivered to the body?
lipids, amino acids, and glucose
What is the difference between Diffusion and Osmosis?
Diffusion is a passive process that allows salt to evenly distribute in water whereas osmosis is is the movement of water to help balance the concentration on either side of the membrane.
Compare Insulin and Glucagon in short term storage:
Insulin is what coverts glucose to glycogen to STORE as reserve fuel. On the other hand glucagon converts glycogen BACK to glucose when low
Compare Insulin and Glucagon in Long term storage:
Insulin is going to be what triggers lipid storage in adipose tissue and the liver. Glucagon is what produces free fatty acids and ketones
What is the set point theory:
The assumption that Hunger is a response to an energy need and we eat to maintain a set point
What is the Positive Incentive Theory?
We eat because we are anticipating the pleasure of eating because it has a positive incentive.
Outline Anorexia Nervosa:
It is a voluntary starvation of oneself
Outline Bulimia Nervosa:
Characterized by binge eating and then purging the food
Outline Binge-Eating Disorder:
The tendency for a person to eat pass the point of fullness
What are the three most common weight loss procedures done today?
Sleeve Gastrectomy
Gastrointestinal Bypass
Gut liner
What is the difference between the 3 weight loss surgeries?
Sleeve Gastro is where there is a reduction in the size of the stomach that consequently reduce the amount of appetite hormone from being released
Gastrointestinal Bypass - Bypass the small intestine entirely
Gut Liner- The least invasive of the three where a liner is placed to absorb any nutrients from being absorbed
What does HAEV stand for?
Heath at every size
Weight loss doesn’t always have to be the goals and health and fitness can exist in all sizes
What is behavioral Compensation?
Behaviors that can change the exposure of the body, the external insulation of the body, and our surroundings
What are some examples of behavioral compensation in reference to Homeostasis?
Covering your body with a blanket
Moving to the shade out of the sun
Shivering to warm up
