Which is the best definition of a hormones?
A chemical found in the human body
A chemical released into the blood in humans
A chemical messenger which travels in the blood to activate cells in target organs
A chemical messenger released by glands
Which of the following is an endocrine gland?
Brain
Sweat glands
Thyroid gland
Lymph nodes
Which of the following is NOT released by the pituitary gland?
progesterone
thyroid stinulating hormone
ADH
FSH
Which of the following is NOT an effect of adrenaline?
Stimulation of the liver to break down glycogen
An increase in basal metabolic rate
Vasoconstriction in arterioles supplying the skin
An increase in heart rate
In the diagram above, where exactly is the temperature regulatory centre in the brain?
Hypothalamus
Pituitary gland
Hippocampus
Temporal lobe
In this image sweat glands are one of the effector bringing about a response. Which of the following are effectors which would lead to a rise in body temperature?
Hair erector muscles in the skin
Muscles surrounding arterioles supplying blood to the skin
Skeletal muscle
All of the above
How does this diagram demonstrate negative feedback?
The response leads to an increase in body temperature
Sweating lowers body temperature and the thermoregularory centre responds to the change.
As body temperature rises, the thermoregulatory centre triggers a response which brings it back to the normal level.
As body temperature rises, the thermoregulatory system stops responding.
Which hormone in the mestrual cycle stimulates a follicle to mature in one of the overies?
progesterone
FSH
oestrogen
LH
Which hormone in the menstrual cycle stimulates the lining of the uterus to thicken and grow?
progesterone
FSH
oestrogen
LH
What are the two main roles of LH?
Stimulates development of the placenta and the release of FSH.
Inhibits the development of a follicle and the release of progesterone.
Causes the lining of the uterus to break down and the release of FSH.
Stimulates ovulation and the development of the follicle into the corpus luteum.
If the lines about are labelled a, b, c and d from top to bottom, which represents progesterone?
a (pink)
b (purple)
c (pale blue)
d (dark blue)
If the lines about are labelled a, b, c and d from top to bottom, which represents oestrogen?
a (pink)
b (purple)
c (pale blue)
d (dark blue)
Which of the following are used as treatments for infertility?
FSH
progesterone
clomifene therapy
IVF
Which two statements are disadvantages of the use of hormones as contraceptives?
They are not as effective as barrier methods.
They can have unpleasant side-effects.
They don't protect against STIs
They are quick and easy to use.
Which part of the body monitors the levels of glucose in the blood?
liver
brain
pituitary gland
pancreas
How does the body respond to low levels of glucose in the blood?
The pancreas releases insulin which raises levels of glucose in the blood.
The pancreas releases glucagon which stimulates the release of glucose from liver and muscle cells.
The pituitary gland stimulates the pancreas and insulin is released.
Liver and muscle cells remove glucose from the blood.
In the graph above, which individual has diabetes?
red
blue
Select the best explanation for the gradual fall in glucose levels shown by the red line.
Glucose is taken up by cells as it is used in respiration.
Insulin stimulates cells to take up glucose.
Some glucose is converted to glycogen.
Glucose gradually breaks down in the blood.
Where in the nephron are all small molecules removed from the blood?
Collecting duct
Loop of Henle
Bowman's capsule
Convoluted tubule
Identify the processes occuring in the proximal convoluted tubule.
diffusion
osmosis
selective reabsorption
active transport
Identify the correct composition of dialysis fluid.
Same concentration of glucose, urea and ions as healthy blood.
Same concentration of glucose and ions as healthy blood and no urea.
Low concentrations of glucose, urea and ions.
High concentrations of glucose and ions but no urea.
Where does urea enter the blood?
small intestine
kidney
spleen
liver
Identify the best explanation of the response to low levels of water in the blood.
The pituitary gland releases ADH which make the collecting duct less permeable to water.
The pituitary gland releases ADH which make the collecting duct more permeable to water.
More urine is produced.
Less urine is produced.
Name the tube which carries urine from the kidney to the bladder.
renal vein
urethra
renal artery
ureter
