Health Assessment of Patients Quiz

C: Steroids are lipid soluble so diffuse through the plasma membrane to bind to a receptor within the cell.

D: Aldosterone promotes the absorption of sodium from the filtrate, while potassium (also a positively charged ion) is secreted to maintain electrical neutrality.

D: Beta cells of the pancreatic islets produce insulin. The alpha cells produce glucagon.

B: The anterior pituitary produces and releases six hormones.

C: PTH causes increased calcium absorption and hence increases blood calcium level.

D: Endocrine glands secrete “circulating” hormones, that is, they are secreted into the blood.

B: Aldosterone causes reclamation of sodium ions from the filtrate and potassium to be secreted in exchange.

A: PTH increases plasma Ca2+ (calcitonin aids in lowering blood calcium).

C: As aldosterone is concerned with the absorption of sodium ions, a_x000d_“mineral”, and aldosterone is produced by the adrenal cortex; it is termed a mineralocorticoid.

B: ADH and OT are produced in the hypothalamus and transported to the posterior pituitary.

C: Thyroxine (or tetraiodothyronine) is converted to triiodothyronine in_x000D_target tissues.

B: Parafollicular (or “C”) cells of the thyroid produce calcitonin which aids in lowering of blood calcium.

A: Thyroid hormones T3 and T4 contain three and four iodine atoms, respectively.

A: Epinephrine is derived from the amino acid tyrosine (so tyrosine is a wrong answer).

C: The acini cells produce digestive enzymes.
