Which of the following is regulated by the kidneys?

1

The medial surface of each kidney has a notch called the

1

At the beginning of the plumbing system of the urinary system, urine leaving the renal papilla is collected in the cuplike structures called

1

The functional unit of the kidney is the

1

Which of the following is a component of the renal corpuscle?

1

Which of the following structures secretes renin when blood pressure in the afferent arteriole drops?

1

Substances pass from the glomerulus and into the Bowman's capsule by

1

The juxtaglomerular cells reside in the

1

The left kidney is often slightly larger and positioned slightly lower than the right kidney

1

Blood is brought to the kidneys by the renal vein

1

Micturition and urination are synonymous

1

The glomerulus is one of the most important capillary networks for survival

1

Once urine enters the renal pelvis, it travels to the renal calyces

1

As the basic functional until of the kidney, the nephron's function is blood processing and urine formation

1

The kidneys are covered with visceral pertoneum

1

Which of the following is not one of the processes of urine formation

1

The movement of water and solutes from the plasma in the glomerulus, across the glomerular-caspular membrane, and into the capsular space of the Bowman's capsule is termed:

1

The movement of molecules out of the peritubular blood and into the tubule for excretion is

1

Which of the following is considered a countercurrent structure

1

Proximal convoluted tubules reabsorb nutrients from the tubule fluid, notably glucose and amino acids, into peritubular blood by a special type of active transport mechanism called sodium contransport

1

Fluid exiting the Henle loop becomes less concentrated with Na+ and Cl- ions

1

A hydrostatic pressure gradient drives the filtration out of the plasma and into the nephron

1

The efferent arteriole has a lager diameter than the afferent arteriole

1

In the renal tubule, Na+ is reabsorbed via active transport

1

Glomerular filtration separates only harmful substances from the blood

1

Urine consists of approximately 75% water

1

Urine has a pH of 4.6 to 8.0 and is generally alkaline

1

More than 99% of filtrates must be reabosorbed from the tubular segments of the nephron.

1

Hydrogen ions are transferred from blood into the urine during which of the following processes?

1

Which of the following steps involved in urine formation allows the blood to retain most body nutrients?
