The adrenal glands are composed of two distinct regions. Which of the following statements correctly describes the hormones produced by each region?

The adrenal cortex secretes epinephrine; the adrenal medulla secretes cortisol

The adrenal cortex secretes aldosterone and cortisol; the adrenal medulla secretes epinephrine and norepinephrine

The adrenal cortex secretes epinephrine and norepinephrine; the adrenal medulla secretes aldosterone

A patient's blood pressure is recorded as 118/76 mmHg. Which of the following correctly identifies these values?

118 mmHg is the diastolic pressure; 76 mmHg is the systolic pressure.

118 mmHg is the systolic pressure; 76 mmHg is the diastolic pressure.

118 mmHg is the mean arterial pressure; 76 mmHg is the pulse pressure.

118 mmHg is the pulse pressure; 76 mmHg is the mean arterial pressure.

Which of the following correctly describes the role of the thyroid gland and its primary hormones?

The thyroid secretes thyroxine (T4) and triiodothyronine (T3), which regulate metabolic rate and are dependent on adequate dietary iodine

The thyroid secretes calcitonin as its only hormone, and calcitonin's primary role is regulating metabolic rate

The thyroid secretes thyroxine (T4) and triiodothyronine (T3), which regulate blood calcium levels and do not require iodine for synthesis

The thyroid secretes parathyroid hormone (PTH), which regulates metabolic rate by stimulating the liver
