Exam 42: Urinary System

Cells in the juxtaglomerular apparatus release renin.

Which hormone tends to increase the amount of urine produced?

The fibrous adventitia covers only the superior surface of the bladder; the rest is covered by the parietal peritoneum.

When compared with most other capillaries in the body, the capillaries in the glomerulus have many more pores.

When aldosterone is released, secretion of _____ occurs.

Explain how the nephron loop establishes a solute concentration gradient from the top of the loop to the bottom of the loop.

The calyces of the kidney join together to form a large collection reservoir called the:

The juxtaglomerular apparatus has components in both the distal convoluted tubule and the afferent arterioles.

Which blood vessels empty into the glomerulus?

Approximately how much blood flows through the kidneys per minute?

The primary cilium of the epithelial cells lining the renal tubules act as mechanoreceptors to regulate the flow of filtrate through the tube.

Micturition is the process of voiding urine.

Which structure of the kidney narrows as it exits the kidney to become the ureter?

The kidneys influence secretion of the hormone aldosterone.

Both ADH and aldosterone attempt to decrease normal urine output.

The renal tubule is made up of simple squamous and simple cuboidal epithelium.

There are how many openings in the urinary bladder?

Contraction of the bladder and relaxation of the internal sphincter are controlled by the sympathetic nervous system.

Reabsorption, as performed in the kidney, may be defined as the:

Match each of the structures of the nephron with its description, function, or location. -Cup-shaped structure surrounding the glomerulus
