Exam 14: The Urinary System

The granular cells of the juxtaglomerular apparatus secrete an enzymatic hormone called __________.

Sodium reabsorption in the proximal tubule plays a pivotal role in reabsorbing glucose,amino acids,H₂O,chloride ions and urea.

The __________ fluid that enters Henle's loop becomes progressively more concentrated as it flows down the __________ limb.

Figure 14-26 Use the figure above (Figure 14-26)to answer the corresponding questions.​ -Which number in the figure represents blood-borne vasopressin binding with its receptor sites on the basolateral membrane of a principal cell?​

The tubuloglomerular filtration mechanism involves the glomerular apparatus.

Regardless of cause,renal failure can manifest itself either as painful renal failure or non-painful renal failure.

Outline the role of the kidneys in the urinary system.

The rate of glomerular filtration depends on the filtration coefficient as well as on the net filtration pressure.

How are glucose and amino acids reabsorbed in the proximal tubule?​

What is the main stimulus for secretion of the hormone aldosterone from the adrenal cortex?​

All plasma constituents filtered,secreted and reabsorbed remain in the tubules and pass into the renal pelvis to be excreted as urine.

Discuss the role of vasopressin in the urinary system.

The basement membrane is a(n)__________ gelatinous layer composed of collagen and glycoproteins that is sandwiched between the __________ and Bowman's capsule.

The most prevalent ions secreted by the tubules are:​

Because the organic ion secretory carriers are not very selective,different drugs can compete for binding sites on the same carrier.

Clinical measurement of blood urea nitrogen (BUN)is a crude assessment of kidney function.

Describe how hydrogen ion secretion impacts acid-base balance.

Bilirubin is a waste product in urine derived from:

To be reabsorbed,a substance must cross the __________ membrane of the tubular cell to enter the interstitial fluid.

Three physical forces are involved in glomerular filtration: glomerular capillary blood pressure,plasma-colloid osmotic pressure,and Bowman's capsule hydrostatic pressure.
