The renal pyramid is

a conical-shaped structure that is located in the renal medulla

Which of the following is a primary function of the distal convoluted tubule?

active secretion of ions, acids, drugs, and toxins

The vasa recta

are long, straight capillaries that parallel the nephron loop deep into the renal medulla

Renal columns are

bands of the renal cortex that extend toward the renal sinus

The portion of the nephron that attaches to the collecting system is the

distal convoluted tubule

The cup-shaped chamber, or the expanded end of a nephron, is known as the

glomerular capsule

Which of the following are components of a renal capsule

glomerulus and glomeruler capsule

The renal ___ is the site at which the renal artery and renal nerve enter and the renal vein exits.

hilum

Major calyces are

large branches that combine to form the renal pelvis

The visceral epithelium, which covers the glomerular capillaries of the glomerular capsule, consists of

podocytes

The kidneys

produce urine

By adjusting the volume of water lost in urine, and releasing erythropoietin and renin, the urinary system specifically functions in

regulating blood pressure

in which renal component does urine production begin?

renal cortex

The large, funnel-shaped chamber that connects to the ureter is called the

renal pelvis

Considering the spatial relationship of the kidneys, the ___ kidney often sits slightly ___ than the ___ kidney.

right;lower;left

Why does the perituble fluid of the renal medulla contain an unusually high solute concentration?

the ascending limb of the nephron loop is not permeable to water and solutes

Which of the following is CORRECT about the location of the kidney(s)?

the kidneys are bilateral and retroperitoneal

Which of the following transports urine from the kidney toward the bladder

ureter

Organs of the urinary system that are actively involved with urine transport are the

urethra and ureters

Urine is temporarily stored the

urinary bladder
