These compartments are iso-osmotic.

The major ICF cation is calcium.

Water moves freely between these compartments.

More fluid is found in the ICF compartment than the ECF compartment.

All of the above

Glucose

Inulin

Sodium

It does not involve transepithelial transport

It is important for the elimination of metabolic waste products from the body

It occurs mainly via passive transport

It involves the direct movement of a substance from glomerular capillaries into the tubular lumen

(A) and (B).

decreased plasma volume.

increased plasma osmolarity.

ingestion of alcohol.

It is synthesised by the posterior pituitary.

It reduces the permeability of the distal tubule and collecting duct cells to water.

It prevents urine production during periods of water deprivation until water balance is restored.

Its mechanism of action involves activation of the cyclic AMP second-messenger system within the tubular cells.

increased mean arterial blood pressure.

increased hydrostatic pressure in the afferent renal arterioles.

(A), (B) and (C).

increased atrial distension.
