Explanation
Matching Endocrine Glands to Hormones in Human Females
Steps:
- Identify glands: Assume 1=pituitary, 2=adrenal, 3=pancreas, 4=ovary based on standard female anatomy.
- Recall hormones: Pituitary secretes FSH (follicle-stimulating hormone for reproduction); adrenal produces adrenaline (stress response); pancreas releases insulin (blood sugar regulation); ovary makes oestrogen (female sex characteristics).
- Match to options: Option B aligns as FSH (1), adrenaline (2), insulin (3), oestrogen (4).
- Verify mismatches: Other options swap hormones incorrectly.
Why B is correct:
- B correctly assigns hormones to glands per endocrine definitions: FSH from anterior pituitary stimulates ovarian follicles; adrenaline from adrenal medulla triggers fight-or-flight; insulin from pancreatic beta cells lowers blood glucose; oestrogen from ovaries regulates menstrual cycle.
Why the others are wrong:
- A: Misassigns adrenaline to 1 (pituitary, not adrenal) and FSH to 2 (adrenal, not pituitary).
- C: Starts with oestrogen for 1 (pituitary, not ovary) and ends with adrenaline for 4 (ovary, not adrenal).
- D: Identical to C, so same error in gland-hormone pairing.
Final answer: B
