Definition of urinary system
The urinary system or urinary tract produces, stores, and eliminates urine and is composed two kidneys, two ureters, the bladder, and the urethra.
Examples of urinary system in the following topics:
- The urogenital system arises during the fourth week of development from urogenital ridges in the intermediate mesoderm on each side of the primitive aorta.
- The nephrogenic ridge is the part of the urogenital ridge that forms the urinary system.
- The urinary bladder develops from the upper end of the urogenital sinus, which is continuous with the allantois.
- The urinary system develops from the intermediate mesoderm during prenatal development.
- The urinary system (see Figure 1) is a group of organs in the body concerned with filtering out excess fluid and other substances from the bloodstream to help maintain homeostasis for optimal cell and tissue metabolism.
- The urinary system organs include the kidneys, ureters, bladder, and urethra.
- Kidneys are the most complex and critical part of the urinary system.
- The urinary system maintains blood homeostasis by filtering out excess fluid and other substances from the bloodstream and secreting waste.
- The organs, tubes, muscles, and nerves that work together to create, store, and carry urine are referred to as the urinary system.
- The urinary system includes two kidneys, two ureters, the bladder, two sphincter muscles, and the urethra.
- If the urinary system is healthy, the bladder can hold up to 16 ounces (2 cups) of urine comfortably for 2 to 5 hours.
- Urinary organs include the kidneys, ureters, bladder, and urethra.
- The kidneys are part of the urinary system, which also includes the ureters and the bladder.
- Bladder control can be affected by muscle changes and changes in the reproductive system.
- Aging also increases the risk for urinary disorders such as acute and chronic kidney failure, urinary incontinence, leakage, or retention, bladder, and other urinary tract infections.
- Urinary system cancers are associated with advanced age and are more common in the elderly, especially prostate cancer (men) and bladder cancer.
- They are essential in the urinary system and also serve homeostatic functions such as the regulation of electrolytes, maintenance of acid–base balance, and regulation of blood pressure (via maintaining salt and water balance).
- They serve the body as a natural filter of the blood and remove wastes that are diverted to the urinary bladder.
- Technically the prostate is not part of the urinary system, but because of its location and relationship to the urethra, the prostate can (and often does) affect urinary function.
- The development of the reproductive system is a part of prenatal development, and concerns the sex organs.
- Because its location to a large extent overlaps the urinary system, the development of them can also be described together as the development of the urinary and reproductive organs.
