Exam 42: Urinary System

In the proximal tubule of the nephron, glucose and amino acids are transported with sodium and actively move out of the tubule fluid by means of the sodium cotransport mechanism.

Place in correct anatomical order the structures of the pathway of urine leaving the distal tubule, beginning with the number 1. -Renal pelvis

Filtrate in which part of the nephron tubule has the highest osmolality?

The descending limb of the loop of Henle is usually in osmotic equilibrium with the interstitial fluid.

The prostatic urethra is found only in men.

An increase in ADH causes a decrease in the osmolarity of urine.

Mesangial cells may have the same role in the nephron as the glia cells do in the nervous system.

Blood leaves the glomerulus through efferent arterioles and then moves into peritubular capillaries.

The calyx surrounds the renal papilla.

ANH reinforces and adds to the effect of aldosterone.

A glomerulus is a group of capillaries located in a Bowman capsule.

Substances travel from the glomerulus into Bowman capsule by the process of:

The mechanism for voiding begins with:

List functions of the urinary bladder.

The kidney filters out only harmful and excess material.

What effect do aldosterone and antidiuretic hormone (ADH) have on urine volume?

Autoregulation of glomerular filtration by tubuloglomerular feedback helps protect the kidney:

If the Tmₐₓ for glucose in the nephron was 300 mg/100 ml and a person had blood glucose level of 380 mg/100 ml, there would be:

In both males and females, the urethra serves urinary and reproductive functions.

Podocytes on the parietal walls of Bowman capsule help support the slit diaphragms that allow filtrate to leave the blood and enter Bowman capsule.
