The functional and structural unit of the kidneys is the ___

Nephron

Which of the following does NOT describe the juxtaglomerular complex?

Its macula densa cells produce aldosterone

If GFR is too low, needed substances may pass so quickly through the renal tubules that they are not absorbed and instead lost in urine

False

Glomerular capillaries are drained by efferent arterioles whose diameter is smaller then afferent arterioles which creates the high blood pressure needed to drive filtration

True

The function of angiotensin II is to ___

Constrict arterioles and increase blood pressure

Blood pressure in the renal glomerulus is lower than most parts of the body to conserve body water

False

The rate of kidney filtrate formation would normally be dependent upon all the following factors except;

Blood calcium level

When given to a patient, which of the following would increase their urinary output?

Intravenous saline

Upon reaching what point in the nephron is reabsorption dependent upon the body's needs at that time and regulated by hormones?

Distal convoluted tubule

An increase in the permeability of the cells of the collecting tubule to water is due to a(n)

Increase in the production of ADH

The kidneys are stimulated to produce renin ___

By a decrease in blood pressure

True

Tubular secretion is effective in controlling pH

True

___ are chemicals that enhance urinary output

Diuretics

Which of these should NOT appear in urine?

Glucose

Relaxation of the ___, a skeletal muscle under conscious control, allows urine to leave the bladder during micturition

External urethral sphincter

Which of the following is NOT necessary for micturition to occur?

The pontine storage center must be activated

Which of the following would NOT inhibit micturition?

Detrusor contraction

Which of the following acts as the trigger for the initiation of micturition (voiding) ?

The stretching of the bladder wall

Which part of the brain controls the micturition reflex?

Pons

Which vessels are most intimate with the nephron loop and serve as a point to collect ions and water back into the blood?

Vasa recta

Which part of the renal tubule has dense microvilli?

Proximal collecting tubule

Why is the proximal convoluted tubule lined with dense microvilli?

To allow water and other chemical compounds to be reabsorbed into the blood

Which of the following is NOT a characteristic of the cortical nephrons?

Their nephron loop is closely wrapped with vasa recta

What structure receives blood from the efferent arteriole of a juxtamedullary nephron?

Vasa recta

Which capillary bed produces filtrate?
