- 2 Ureters: Muscular tubes, approximately 25 cm long, that carry urine from kidneys to the urinary bladder.
- 1 Urinary Bladder: Serves as a reservoir for urine; assumes a pyramidal shape when empty.
- 1 Urethra: Short and wide tube responsible for urine excretion from the bladder.
Kidney Details
- Shape: Bean-shaped with upper and posterior surfaces.
- Location: Extends from the last rib to the third lumbar vertebra.
Ureter Characteristics
- Functions as a conduit for urine transmission.
- Exhibits multiple constrictions, particularly at its beginning, middle, and end points.
Urinary Bladder Function
- Acts as a temporary storage site for urine until excretion.
- Empty bladder is pyramidal in appearance.
Urethra Structure
- Length: Males have a urethra about 20 cm long, while females' is approximately 4 cm long.
