ADH is created in the:
Hypothalamus
Posterior Pituitary Gland
Brain
Kidney
ADH is released from the pituitary gland into the:
Circulatory system
Endocrine system
Nervous system
All of the above
When ADH is secreted, urine will:
Be more dilute
Be more concentrated
Have a larger volume
All of the above
When you drink a larger volume of water than is required by your body tissues:
ADH secretion will be increased
ADH secretion will be inhibited
ADH secretion will not be affected
None of the above
Cells that detect high blood concentration are called:
Chemoreceptors
Osmoreceptors
Thermoreceptors
Nociceptors
Changes in blood volume and concentration are detected in the brain cells in the:
Posterior Pituitary Gland
Anterior Pituitary Gland
Thalamus
Hypothalamus
Anti-diuretic hormone (ADH) is released by which gland of the endocrine system
Thyroid
Pituitary
Ovaries
Adrenal
What classification of receptors detect changes in water potential in the blood
Thermoreceptors
Proprioceptors
Photoreceptors
Osmoreceptors
Anti-diuretic hormone (ADH) affects the permeability of which section of the nephron tubules
Proximal (first) convoluted/coiled tubual
Loop of Henle
Distal (second) convoluted/coiled tubual
Collecting duct
If you are dehydrated (low water potential in the blood), the body must conserve water. To do so, the brain triggers the pituitary gland to ...
release MORE ADH, making the collecting duct MORE permeable
release LESS ADH, making the collecting duct LESS permeable
release MORE ADH, making the collecting duct LESS permeable
release LESS ADH, making the collecting duct MORE permeable
If you are over-hydrated (high water potential in the blood), the body must excrete excess water. To do so, the brain triggers the pituitary gland to ...
release MORE ADH, making the collecting duct MORE permeable
release LESS ADH, making the collecting duct LESS permeable
release MORE ADH, making the collecting duct LESS permeable
release LESS ADH, making the collecting duct MORE permeable
what is osmoregulation?
Control of water and salt in the body
Control of blood pressure in the body
Control of blood glucose in the body
sodium and postassium ions are pumped out of the ascending limb of the loop of the Henle to
create a high water potential in the medulla
create a low water potential in the medulla
excrete excess ions into the urine
allow water to be reabsorbed into the proximal convoluted tubule by osmosis
ADH causes specific protein channels to move into the membranes of certain cells in the nephron so that more water can be absorbed by osmosis. What are these called?
aquaporins
active transport
tight junctions
desmosomes
ADH
Inhibits the absorption of water in the proximal convoluted tubule
Inhibits the absorption of water in the distal convoluted tubule
Increases the absorption of water in the proximal convoluted tubule
Increases the absorption of water in the distal convoluted tubule
When an organism has sweated a great deal and has not drank much water, this will be detected as:
Low blood pressure
Low blood volume
High blood concentration
All of the above
Changes in blood volume and concentration are detected in the brain cells in the:
Posterior Pituitary Gland
Anterior Pituitary Gland
Thalamus
Hypothalamus
Which area of the brain contains the receptors responsible for detecting changes in water potential
Hypothalamus
Medulla Oblongata
Amygdala
Hippocampus
The control of water and solute concentrations in the blood to maintain a constant water potential in the body is called ...
osmoregulation
metabolism
anabolism
catabolism
The amount of water in the blood plasma is controlled by ...
kidneys
heart
liver
ADH
ADH stands for ...
antidehidration hormone
antidiuretic hormone
antidiarrhea hormone
anti direction hormone
When we drink too much water, the pituitary gland will releases ...
more ADH
less ADH
When we lose water through sweating, our pituitary gland will release ...
more ADH
less ADH
What is the name of X?
pituitary gland
hypothalamus
nephron
brain
What is the function of Y?
to produce ADH
to release ADH
increases the reabsorption of water in the nephrons
inhibit the reabsorption of water in the nephrons
