hormones and the renal system.

Question 1

Hydrostatic pressure

Secretion

Osmotic pressure

Active transport

Diffusion

Answer 1

Hydrostatic pressure

Question 2

Which of the following occurs in the kidney nephron?

Selective reabsorption

Activation of baroreceptors

Production of angiotensin

Peristalsis

Production of insulin

Answer 2

Selective reabsorption

Question 3

Maintaining electrolyte levels in homeostasis is essential. Which of these statements is correct?

Cells actively pump potassium out of cells to take in sodium ions.

Sodium is the major cation in extracellular fluid.

Calcium, potassium and magnesium are all examples of anions.

Homeostasis is maintained through hormonal control of osmosis.

Magnesium ions are used to transmit nerve impulses.

Answer 3

Sodium is the major cation in extracellular fluid.

Question 4

What is the main function of the kidney in pharmacokinetics?

Absorption of drug

Metabolism of drugs

Distribution of drugs

Excretion of drugs

Storage of drugs

Answer 4

Excretion of drugs

Question 5

Jayne is 62 years old and has hypertension. She is having her blood pressure checked by the practice nurse.

When a person develops hypertension, they start to release more atrial natriuretic peptide (ANP), what effect does this hormone have on the kidneys?

ANP triggers the release of antidiuretic hormone.

ANP increases the loss of water and sodium from the nephron.

ANP reduces the appetite in the older adult.

ANP triggers the release of renin from the juxtamedullary cells.

ANP increases production of aldosterone.

Answer 5

ANP increases the loss of water and sodium from the nephron.
