Anatomy of the Urinary System
1. The urinary system has ____ kidneys, _____ ureters, and _____ bladder.
2 kidneys, 2 ureters, 1 bladder
2. Describe the shape, weight and location of the adult kidney.
The adult kidney is shaped like a bean, weighs 5 ounces, and is located between the T12 and L3
vertebrae
3. The ____glands are located on top of each kidney.
Adrenal
4. Describe the three layers of protective tissue that surround the kidney.
The renal capsule is a tough fibrous layer of the kidney that protects from injury and infection,
the adipose capsule is the next layer that is fatty and protects the kidney from trauma, the
outer layer is the renal fascia and it is made up of dense fibrous connective tissue which keeps
the kidney in place
5. A vertical cross section shows what three regions inside the kidney?
The renal cortex, the medulla, the renal pelvis
6. The _____ is a continuous outer region with several cortical columns.
Renal cortex
7. The renal medulla is divided into sections called _____.
Pyramids
8. Describe the renal pelvis.
The renal pelvis is made up a funnel shaped tube that connects to the ureter, the calyces of the
renal pelvis collect urine and drain it into the ureter, where it is transported to the bladder
9. Label blood supply to and within the kidney. Make any notes/comments here.
Renal artery > segmental artery > interlobar artery > arcuate arteries > interlobular arteries >
afferent arterioles > efferent arterioles > capillaries > interlobular veins > arcuate veins >
interlobar veins > renal vein
10. Trace the flow of blood through the vessels of the kidney from renal artery into the
glomerulus and back to the renal vein.
Renal artery > segmental artery > interlobar artery > arcuate arteries > interlobular arteries >
afferent arterioles > efferent arterioles > capillaries > interlobular veins > arcuate veins >

, interlobar veins > renal vein
11. Input from the _______ adjusts the diameter of the renal arteries thereby regulating
renal blood flow.
Sympathetic nervous system
12. Urine is carried from the kidneys to the bladder by thin muscular tubes called ____.
Ureters
13. ______are sphincters located where the ureters enter the bladder.
Ureterovesical valves
14. Describe the three layers of the ureter wall.
Inner lining- made of transitional epithelium, continuous with kidney linen
Middle layer- 2 sheets of muscle, longitudinal & circular
Outer adventitia- fibrous connective tissue
15. Describe the urinary bladder. Compare male and female locations.
The urinary bladder is a hollow, muscular, elastic pouch that receive & stores urine, in females
the bladder is below the uterus and in front of the vagine where in males the bladder is in front
of the rectum, the bladder can hold more in males
16. Both ureters open into the bladder via the _____.
Ureteral orifices
17. Describe the three layers of the bladder.
The outer layer - adventitia- is fibrous connective tissue, the middle layer is the muscular layer
(detrusor muscle) inner mucosal layer is made up of transitional epithelium
18. Describe the bladder when it is full and when it is empty.
When he bladder is empty it collapses into a pyramid shae and as it is filed, it swells with urine
and becomes pear shaped
19. Label the parts of the bladder and its location in males and females.
20. Describe the two sphincters of the bladder.
The internal urethral sphincter is at the base of the bladder to prevent urine from leaving, it is
involuntarily controlled and the external urethral sphincter is voluntarily controlled
