Exam 31: A: Urinary System

Voiding and micturition refer to the same process.

ANH reinforces and adds to the effect of aldosterone.

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

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

The kidney could best be described as pear-shaped.

Proteinuria can indicate damage in the glomerular-capsular membrane.

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

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

The volume of urine is normally determined by the glomerular filtration rate.

Mesangial cells may have a role in regulating blood flow through the glomerular loop.

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

The renal artery branches directly from the abdominal aorta.

Urine consists of approximately 75% water.

The osmolality of the urine excreted by the body can be as high as the osmolality in the medulla's interstitial fluid.

Just like the kidneys,the ureters are retroperitoneal.

One important function of the slit diaphragms is the prevention of large molecules such as proteins from passing through.

Renin is released in response to a rise in blood pressure in the afferent arteriole.

Even though urea is a waste product,it is reabsorbed into the blood in the proximal convoluted tubule.

The proximal tubule is the second part of the nephron but the first part of the renal tubules.

The tubes of the nephron are about 3 cm long.
