Exam 14: The Kidneys and Regulation of Water and Inorganic Ions

A substance that interferes with the active transport of sodium in the cortical collecting ducts will also interfere with potassium reabsorption.

The reabsorption of water in the nephron is accomplished as it follows the diffusion gradient created by sodium reabsorption.

Hypoventilation is a cause of

Compared to a normal person,a person experiencing metabolic acidosis will have

Functions of the kidneys include

Cardiac arrhythmias may be a clinical sign of either potassium depletion or potassium excess.

Diabetes insipidus is a disease that is associated with a deficiency of

The countercurrent multiplier system of the kidney

A diuretic is any drug that increases the volume of urine excreted as a result of inhibiting sodium reabsorption.

Voluntary control of micturition involves controlling motor input to the muscles of the external urethral sphincter.

The active transport of sodium

Following ingestion of a large amount of salt,

Stimuli for the increased secretion of aldosterone include

Constriction of the ________ decreases hydrostatic pressure in the nephron's filtering structures; the _________.

The kidneys work to rectify metabolic acidosis and alkalosis but have no effect on respiratory acidosis and alkalosis.
