Question 20

Where is the function (job) of the hormone adrenaline?

Answer 20

* Increases the heart rate. * Increases breathing rate. * Boosts the delivery of oxygen and glucose to the brain and muscles, preparing the body for ‘flight or fight’.

Question 21

Where is the function (job) of the hormone ADH?

Answer 21

Water retention by the kidneys

Question 22

Where is the function (job) of the hormone insulin?

Answer 22

Causes glucose to move from the blood into the cells. In liver and muscle cells excess glucose is converted to glycogen for storage.

Question 23

Where is the function (job) of the hormone testosterone?

Answer 23

* Main male reproductive hormone * Stimulates sperm production * Causes secondary sexual characteristics

Question 24

Where is the function (job) of the hormone progesterone?

Answer 24

Maintains the lining of the uterus during the middle part of the menstrual cycle and during pregnancy.

Question 25

Where is the function (job) of the hormone oestrogen?

Answer 25

\* Stops production of FSH (so only 1 egg matures at a time) \* Repairs, thickens and maintains the uterus lining \* Stimulates the pituitary gland to release LH \* Causes secondary sexual characteristics

Question 26

Where is the function (job) of the hormone FSH?

Answer 26

Causes an egg to mature in an ovary.Stimulates the ovaries to release oestrogen

Question 27

Where is the function (job) of the hormone LH?

Answer 27

Triggers ovulation (the release of a mature egg) from an ovary

Question 28

Where is the pituitary gland found?

Answer 28

In the brain

Question 29

HIGHER - What happens when there are high ADH levels in the blood?

Answer 29

\* More water is resorbed by the (nephrones / kidney tubules in the) kidneys back in to the blood. \* This is an example of negative feedback.

Question 30

What happens when there is too little water in the blood?

Answer 30

The hypothalamus detects this and causes the pituitary gland to release more ADH into the blood.

Question 31

Where is the hypothalamus found?

Answer 31

In the brain

Question 32

HIGHER - What happens when there are low ADH levels in the blood?

Answer 32

\* Less water is resorbed by the (nephrons in the) kidneys back in to the blood. \* This is an example of negative feedback.

Question 33

What happens when there is too little water in the blood?

Answer 33

The hypothalamus detects this and causes the pituitary gland to release more ADH into the blood.

Question 34

Answer 34

Oestrogen or progesterone

Question 35

Which hormones are found in fertility drugs?

Answer 37

Glands

Question 38

What is the function (job) of the pituitary gland?

Question 40

Exam Question (May 2012): One of the characteristics of living organisms is the ability to respond to a change in their surroundings. In mammals, such as humans, responses are controlled by nervous or hormonal communication. (a) ADH is an example of a hormone. (i) Where is ADH produced? (1 mark) (ii) Describe the effects of ADH in the body (3 marks) (b) Describe two ways in which nervous communication differs from hormonal communication (2 marks)

Answer 40

Answers: a) i) hypothalamus / pituitary ii) 1. Collecting duct; 2. More permeable 3. More water reabsorbed into blood / blood more dilute 4. Osmosis; 5. Urine concentrated / less water in urine / less urine b) Nervous = i) faster; ii) electrical impulses; iii) in neurones; iv) shorter lasting; v) target cells Hormonal = i) Slower ii) chemical; iii) in the blood; iv) longer lasting; v) all around body
