BIO 202 ACTUAL TEST PAPER 2026
QUESTIONS WITH SOLUTIONS GRADED A+
⩥ Secondary endocrine organs. Answer: Organs with other primary
functions that also secrete hormones (pancreas, heart, kidneys, gonads)
⩥ Endocrine glands. Answer: Ductless glands that release hormones into
the bloodstream
⩥ Exocrine glands. Answer: Glands that secrete substances through
ducts onto surfaces or into cavities
⩥ Zona glomerulosa. Answer: Outer adrenal cortex layer; secretes
aldosterone for sodium and blood pressure regulation
⩥ Zona fasciculata. Answer: Middle adrenal cortex layer; secretes
cortisol for stress and metabolism
⩥ Zona reticularis. Answer: Inner adrenal cortex layer; secretes
androgens (sex hormone precursors)
⩥ Insulin. Answer: Lowers blood glucose by promoting uptake into cells
,⩥ Glucagon. Answer: Raises blood glucose by stimulating glycogen
breakdown
⩥ Somatostatin. Answer: Inhibits insulin and glucagon secretion
⩥ Pancreatic polypeptide. Answer: Regulates pancreatic digestive
activity
⩥ Hypothalamus hormones. Answer: TRH, CRH, GnRH, GHRH,
dopamine (control anterior pituitary)
⩥ Anterior pituitary hormones. Answer: GH, TSH, ACTH, PRL, FSH,
LH
⩥ TSH. Answer: Stimulates thyroid hormone release
⩥ ACTH. Answer: Stimulates cortisol release from adrenal cortex
⩥ GH. Answer: Stimulates growth and metabolism
⩥ Prolactin. Answer: Stimulates milk production
⩥ FSH. Answer: Stimulates gamete production
, ⩥ LH. Answer: Triggers ovulation and testosterone production
⩥ Thyroid hormones. Answer: T3 and T4 increase metabolic rate
⩥ Parathyroid hormone (PTH). Answer: Increases blood calcium levels
⩥ Epinephrine. Answer: Fight-or-flight response hormone from adrenal
medulla
⩥ Negative feedback mechanism. Answer: Hormone production
decreases when levels are sufficient
⩥ Positive feedback mechanism. Answer: Hormone production increases
in response to a stimulus (e.g., childbirth)
⩥ Diabetes mellitus. Answer: Disease of high blood glucose due to
insulin issues
⩥ Cushing's syndrome. Answer: Excess cortisol production
⩥ Addison's disease. Answer: Deficiency of cortisol and aldosterone
