Study Notes
Urinary Elimination
- Normal bladder capacity: 600-1000ml
- The detrusor muscle and internal sphincter work together to retain urine in the bladder
- The urinary meatus is the exit point for urination
Urethra
- Transports urine from the urinary bladder to the exterior of the body
- Has 2 sphincters: internal and external
- Relaxing the external sphincter starts the flow of urine for excretion
- In males, the urethra is about 20cm long and serves as a common outlet for the reproductive system and urinary elimination
- In females, the urethra is 4-6.5cm long, making women more susceptible to UTIs due to the shorter length
Urination (Micturition/Voiding)
- Process of emptying the urinary bladder
- Pressure arises when urine accumulates in the bladder, typically when it reaches 150-250ml in adults or 50-200ml in children
- Urination is initiated when the detrusor muscle contracts, internal and external sphincters relax, and abdominal wall muscles slightly contract
- Micturition can be delayed by voluntary contraction of the external sphincter
Characteristics of Urine
- Normal: 1-1.8 L/day
- Abnormal: Anuria (zero urine production) or other variations
Functions of the Urinary System
- Removes waste products from the blood
- Eliminates waste products from the body
- Regulates blood volume
- Maintains a balance of blood pH and electrolytes
Kidneys
- Maintain the composition and volume of body fluids
- Excrete body wastes through urine
Ureters
- Transport urine from the renal pelvis to the urinary bladder
Urinary Bladder
- Temporarily stores urine and empties periodically when full
- Sends a signal to the spinal cord when it becomes full to signal the need for emptying
