A wave of smooth muscle contractions that propels materials along the axis of a tube. Ex: digestive tract, ureters or the ductus deferens
Peristalsis
Eliminates the dissolved organic waste products generated by cells throughout the body:

Function of the urinary system

Function of the urinary system
Located in the retroperitoneal space where urine is formed:
Kidneys
Ureters:
Used for transporting the urine to the storage compartment, the bladder, via peristalsis.
Passes through this to exit the body:
Urethra
Components of the urinary system are:
- Kidneys
- Ureters
- Urinary Bladder
- Urethra
Temporarily stores urine prior to elimination:
Urinary bladder
The kidney is divided into:
The outer cortex and inner medulla
Urine production occurs where:
Renal pyraminds
The medulla contains 6 to 18:
Renal pyramids
The tip of the renal pyramid is called:
The renal papillae
Renal papilla discharge urine into a cup-shaped drain called:
Minor calyx
4 or 5 minor calyces merge to form:
Major calyces
