WGU D446 ENDOCRINE SYSTEM FINAL
TEST 2026 QUESTIONS WITH CORRECT
ANSWERS GRADED A+
◍ Positive Feedback.
Answer: when a change initiates a response and that response intensifies the
original changeEx: contractions of the uterus during child birth
◍ Thyroid Gland.
Answer: two lobes on each side of larynx that contain tens of thousands of
follicles; each sphere of cuboidal glandular cells surrounding colloid, which
is thyroid hormone precursor
◍ hormones produced by pancreas.
Answer: alpha cells produce glucogon; beta cells produce insulin; delta cells
produce somatostatin
◍ Follicle Stimulating Hormone (FSH).
Answer: Females: stimulates growth/development of ovarian follicles; also
stimulates the cells lining the follicles to produce/secrete estrogen; used to
superovulateMales: stimulates spermatogenesis in the testes
◍ Calcitonin.
Answer: thyroid gland; produced by C cells (parafollicular cells) located
between thyroid follicles; maintains homeostasis of blood calcium levels;
prevents hypercalcemia by decreasing blood calcium levels if they get too
high; encourages excess calcium to be deposited into the bones
◍ Pineal Gland.
Answer:
◍ Thyroid Histology Slide.
, Answer:
◍ Male Hormone.
Answer: testosterone
◍ Most endocrine glands work like a thermostat which is via:.
Answer: negative feedback
◍ Calorigenic Effect.
Answer: allows an animal to generate heat/maintain a constant body
temperature by increasing their metabolism; production of thyroid hormone
increases with exposure to cold temperatures
◍ Ovaries.
Answer:
◍ Cortex of the adrenal gland produces (as directed by ACTH release).
Answer: Glucocorticoid hormones (cortisol); mineralocorticoid hormones
(aldosterone); sex hormones (androgens and estrogens) small amount with
minimal effect
◍ what does the endocrine system work together with?.
Answer: nervous system to maintain homeostasis
◍ Thymus Gland.
Answer: D
◍ Endocrine System Model.
Answer: A-Pituitary Gland B-Thyroid GlandC-Adrenal GlandD-Testes E-
PancreasF-Parathyroid Gland G. Ovaries
◍ posterior pituitary gland storage.
Answer: does not make hormones but stores oxytocin and Antidiuretic
hormone (ADH)
◍ Target cell.
Answer: "lock and key" arrangement causes a change in activity of target
cell; growth hormone: all cells; Prolactin: mammary tissue
