Study Notes
Urinary System - Key Structures and Functions
-
Primary Functions:
- Excretion: Removal of metabolic waste products from the body.
- Elimination: Discharge of these wastes out of the body.
-
Bladder Capacity:
- The bladder can hold between one and one-half to two cups of urine, approximately 400-500 ml.
- As the bladder fills, nerve signals are sent to the brain.
Urinary System - Objectives
- State the primary functions
- Identify the key structures
- Describe the process of urine formation
- List common urinary disorders
Urinary System - Structures
-
Kidney:
- Located in the abdominal cavity.
- Bean-shaped organs.
- Produce urine.
- Contain nephrons (the smallest functional unit).
-
Nephron:
- The smallest functional unit of the kidney.
- Located inside the kidney.
- A micro-filtering unit.
-
Ureter:
- A tube.
- Transports urine from the kidneys to the bladder.
-
Bladder:
- A muscular sac.
- Temporarily stores urine prior to urination.
-
Urethra:
- A tube.
- Transports urine from the bladder to the exterior of the body.
Urine Formation - Process
-
Filtration:
- Blood pressure forces water and solutes through the filters (in the nephrons).
-
Reabsorption:
- Removal of water and solutes from the filtrate.
-
Secretion:
- Preparing substances for excretion.
Common Urinary Disorders
-
Urinary Tract Infection (UTI):
- Infection of the urinary system.
- Can affect any part of the urinary system.
- Commonly caused by bacterial infections (e.g., E. coli).
- Symptoms include: pain with urination, cloudy/foul-smelling urine, urinary incontinence, and frequent urination.
-
Renal Failure (Kidney Failure):
- When one or both kidneys stop functioning.
- Can be temporary or chronic (worsening over time).
- Common causes include diabetes, high blood pressure, and other chronic kidney diseases.
- May not have symptoms in early stages. Chronic symptoms can include fatigue, confusion/concentration problems, swelling in hands/feet/face, increased urination frequency, and dry/itchy skin.
