Homeostasis - WACE Human Biology
ATAR Unit 3 Exam with complete
solutions
Stimulates the release of ADH - Correct Answers -High osmotic pressure
Gland that releases ADH - Correct Answers -Posterior Pituitary gland
The effect of ADH - Correct Answers -Increases permeability of distal convoluted tubule
and collecting tubule allowing for increased water re-absorption into blood
Stimulates the secretion of Aldosterone - Correct Answers -Low blood pressure
Detects changes in osmotic pressure - Correct Answers -Osmoreceptor
Detects changes in blood pressure - Correct Answers -Baroreceptors
Gland that secretes Aldosterone - Correct Answers -Adrenal Cortex
The effects of decreased breathing rate - Correct Answers -Increase CO2 levels and
decreased pH levels
Why pH levels decrease as breathing rate decreases - Correct Answers -An increase in
CO2 leads to an increase in H+ concentration which reduces pH
Detects increase in H+ levels - Correct Answers -Chemoreceptors in aortic and carotid
bodies and medulla oblongata
Detects increase in CO2 concentration levels - Correct Answers -Chemoreceptors in
medulla oblongata
The effect of Aldosterone - Correct Answers -Increases Na absorption into blood, Na is
dissolved into water therefore increasing water re-absorption
Lipogenesis - Correct Answers -Formation of fat from glucose
Glycogenolysis - Correct Answers -Breakdown of glycogen to glucose
Gluconeogenesis - Correct Answers -Formation of glucose from fats and amino acids
