2. Introduction to the Urinary System
The urinary system rids the body of waste and assists in the regulation of water and chemical balance
Its functions include:
The excretion of urine , a liquid waste produced in the body
The maintenance of water balance; water balance occurs when the intake of water equals the output of water
Regulation of chemical balance or acid-base balance

4. Structures of the Urinary System
Two kidneys are located at the back of the upper abdomen
Their primary function is to filter waste products from the blood
Each kidney has the following structure:
Capsule- sac surrounding the kidney
Cortex- outer part of the kidney
Medulla- inner part of the inner part of the kidney

5. Structures of the Urinary System
Nephron- chief filtering system mechanism of the kidney
Convoluted tubule- a tiny twisted tube
Bowman’s capsule- cuplike capsule
Glomerulus- a cluster of capillaries in Bowman’s capsule

6. Structures of the Urinary System
Ureters- tubes that carry urine from the kidneys to the urinary bladder
Urinary bladder- a muscular sac that expands to hold the urine received from the kidneys
Urethra- a tube extending from the urinary bladder to the outside of the body. This allows for the excretion of urine
