This medical word root, "lith," means this.
What is stone?
This notch is the passage area for ureters, vessels, and nerves.
What is the hilum?

What is the proximal convoluted tubule (PCT)?
This is the process where useful substances move from the filtrate back into the blood.
What is tubular reabsorption?
This muscular sac stores urine and sits in the pelvic cavity.
What is the urinary bladder?
Where collecting ducts eventually empty urine to continue toward the ureter.
What is the renal pelvis?
This outermost layer of the kidney anchors it in place.

What is micturition?
Interlobar veins unite here before draining into the renal vein.
What is at the base of the renal pyramids?
This is the outer area of the kidney, containing nephrons.
What is the cortex?
These are the innermost cells of Bowman's capsule that help form the filtration membrane.
What are podocytes?
Urine becomes concentrated here as final water reabsorption occurs.
What is the collecting duct?
This tube carries urine from the bladder to outside the body.
What is the urethra?
This hormone, released by the kidney, stimulates red blood cell production.
What is erythropoietin?

What are the renal pyramids?
This is the double-walled structure that surrounds the glomerulus.
What is Bowman's capsule?
This is the process where extra substances are added into the tubule fluid from the blood.

The bladder wall is composed mainly of this type of muscle tissue.
What is the detrusor muscle?
This overall job describes what the kidneys do for the blood.
