Before you begin
- Recall electrical impulses, blood transport, gland secretion and the distinction between a stimulus and a body response.
Work on paper. Try each question before revealing help, and explain why your method works.
Quick readiness check
Which gland sits immediately above a kidney in these diagrams?
What you will learn
- Trace actual organ positions
- Match every gland with its required hormone
Identify the four required endocrine glands in original diagrams
Two separate simplified anatomical models: A adrenal cap above a kidney; B pancreas; C ovaries within pelvis; D testes in scrotum. Not to scale.
| Feature | Meaning |
|---|---|
| A | Adrenal glands → adrenaline |
| B | Pancreas → insulin |
| C | Ovaries → oestrogen |
| D | Testes → testosterone |
Trace actual organ positions
The original diagrams show two alternative anatomical arrangements separately. Both include adrenal glands above the kidneys and a pancreas across the upper abdomen. The diagram with ovaries shows two pelvic ovarian structures; the diagram with testes shows two scrotal structures below the pelvis. The models are simplified views, not scaled specimen photographs.
Letter A ends at the small adrenal cap rather than the larger kidney underneath. Letter B ends at the elongated pancreas in the upper abdomen. C marks an ovary in the ovarian model; D marks a testis in the testicular model. Follow each leader to its endpoint before using the table. The presence of a nearby organ does not make it the labelled target.
Match every gland with its required hormone
The required pairings are adrenal glands with adrenaline, pancreas with insulin, ovaries with oestrogen and testes with testosterone. A gland is an organ producing a substance; the substance is the hormone. When a question asks for both, give both names rather than only the anatomical location or only the chemical name.
The diagrams omit other endocrine glands because this identification task focuses on four required targets. The pancreas has additional secretions, but insulin is its required Core pairing here. The Supplement glucagon pairing is taught later. Ovarian and testicular models are anatomical learning examples and do not classify the learner or place both reproductive arrangements into one body.
Pause and explain
Which complete pair is correct?
Worked example
Identify A–D and state each required hormone.
Show the worked solution
- A adrenal glands: adrenaline; B pancreas: insulin.
- C ovaries: oestrogen; D testes: testosterone.
Answer A adrenal glands–adrenaline; B pancreas–insulin; C ovaries–oestrogen; D testes–testosterone.

Write your answer and reasoning first. Use a hint only if you are stuck. The model solution is for self-checking; your written work is not automatically marked.
Identify A–D and state the four required hormone pairings.
Give me a hint
Use the endpoints in both separate models.
Compare my reasoning
- A adrenal glands/adrenaline and B pancreas/insulin.
- C ovaries/oestrogen and D testes/testosterone.
A adrenal glands–adrenaline; B pancreas–insulin; C ovaries–oestrogen; D testes–testosterone.
Look for these in your work
- Identify all four glands
- Match all four hormones
Which target is within the pelvis, and which lies below it in the scrotum? Give each hormone.
Give me a hint
Compare C in one model and D in the other.
Compare my reasoning
- C ovaries lie within the pelvis and secrete oestrogen.
- D testes lie in the scrotum and secrete testosterone.
C: ovaries within pelvis, oestrogen. D: testes in scrotum below pelvis, testosterone.
Look for these in your work
- Use both positions
- Match both hormone names
An unfamiliar drawing labels a small cap above each kidney as X and an elongated upper-abdominal gland as Y. Identify each and give its Core hormone.
Give me a hint
Position and organ shape provide the supplied evidence.
Compare my reasoning
- X matches adrenal glands and adrenaline.
- Y matches pancreas and insulin.
X: adrenal glands, adrenaline. Y: pancreas, insulin.
Look for these in your work
- Use supplied anatomical features
- Give both required pairs
Common mistakes
- Following A to a kidney instead of its adrenal cap.
- Swapping the ovarian and testicular hormones.
What can you explain now?

Compare with the explanation
Ovaries secrete oestrogen
C is the pelvic ovarian target.

Make it stick
Locate all four diagram targets and recall their four required hormone pairings.
