Cortisol preserves blood sugar by _______
Limiting cellular uptake
Glucagon functions in which gland/organ? What are its functions?
Liver; inhibits lipogenesis, promotes glycogenolysis and gluconeogenesis
The amount of glucose released by the liver is dependent on _____
Exercise intensity and duration
CATS is proportional to ______; causes rapid ____ release into blood from liver
Intensity; glucose
Blood glucose levels spike by _____% following _____activities
40-50%; short duration (ST) HIIT
During work intervals, how much blood glucose flows into muscle cells?
Not a lot, muscles uses own glycogen storage first
In what type of exercise does the amount of glucose released from the liver match glucose uptake by cells (maintaining near resting levels)
Low intensity, long duration
As body is using up a lot of glucose, _____ levels rise in order to maintain circulating glucose levels
Glucagon
Name the 4 hormones that promote lipolysis (HSL activation)?
Epinephrine, NE, cortisol, growth hormone
Insulin reduces inhibition of ___ under SNS activation
HSL
What is the host gland and effect of Prolactin?
Hypothalamus; d creases estrogen and testosterone production – inhibits FSH and gonadotropin releasing hormone (GnRH) release
What is the host gland and effect of ADH?
Pituitary gland; preserves blood volume
What is the host gland and effect of Aldosterone?

Exercise causes ___ to ___% loss in blood volume
10-20%
Residual efcts of ADH and aldosterone can last _____hours post exercise
12-48
Role ADH plays with kidneys
Reabsorbs water from kidneys
ADH maintains blood pressure via ____
Vasoconstriction
Renin activates ______ (plasma protein)
Angiotension
Angiotension–>angio1–>angio2 via___?
ACE (angiotensin converting enzyme)
Exercise and sweating decreases what 4 things I n the blood?

Pancreas
What hormones are released in response to SNS activation?
Epinephrine, NE, Glucocorticoids, glucagon, prolactin, anti Diuretic hormone
Insulin inhibits
Gluconeogenesis
Insulin helps with macronutrient uptake for STORAGE or USAGE?
Storage
Insulin= elevated nutrients to n the blood=lower ______
