Exam 25: The Urinary System

The lining of the male urethra contains:

After birth, growth of nephrons is due to hypertrophy not hyperplasia.

The right kidney is slightly lower than the left due to the position of which organ?

Collecting ducts in the renal cortex and renal medulla drain directly into

Cortical nephrons lack one portion of the renal tubule that is found in juxtamedullary nephrons, the:

The inner most lining of the glomerular capsule, or the visceral layer, consists of

Filtration of blood plasma occurs at the

The movement of water and solutes from the kidney tubules into the bloodstream is

Which areas of the nephron consist of simple cuboidal epithelium? Select all that apply.

Simple squamous epithelium is found in what part of the nephron? Select all that apply.

The proximal convoluted tubule cells have microvilli on their apical surface to assist in reabsorption and secretion.

The internal urethral sphincter is composed of which arrangement and type of muscle fibers? 1) circular 2) longitudinal 3) oblique 4) smooth 5) skeletal

The mass of the kidney decreases in size as an individual ages.

Which of these components would be found in both juxtamedullary and cortical nephrons. Select all that apply.

Juxtaglomerular cells:

The two portions of a nephron that commonly contribute to the juxtaglomerular apparatus are the:

Waste passes from the renal pelvis into this structure, which removes the waste from the kidney.

Which segment of the renal tubule is composed of simple squamous epithelium?

Which of the following substances would be least likely to pass through the fenestrations in the endothelial cells of the glomerulus?

When mesangial cells relax, the surface area of the glomerulus increases causing glomerular filtration to increase.
