Unlike the urinary bladder of vertebrates, the urinary bladder of crustaceans both stores and modifies urine. [50] The bladder consists of two sets of lateral and central lobes. The central lobes sit near the digestive organs and the lateral lobes extend along the front and sides of the crustacean's body cavity. [50]
Current methods of bladder reconstruction include the use of gastrointestinal tissue. However, while this method is effective in improving the function of the bladder, it can actually increases the risk of cancer, and can cause other complications, such as infections, urinary stones, and electrolyte imbalance.
In humans, soluble wastes are excreted primarily by the urinary system and, to a lesser extent in terms of urea, removed by perspiration. [4] In placental mammals, the urinary system consists of the kidneys, ureters, urinary bladder, and urethra. The system produces urine by a process of filtration, reabsorption, and tubular secretion. The ...
Following filtration of blood and further processing, wastes (in the form of urine) exit the kidney via the ureters, tubes made of smooth muscle fibres that propel urine towards the urinary bladder, where it is stored and subsequently expelled through the urethra during urination. The female and male urinary system are very similar, differing ...
The urinary bladder is the organ that collects urine from the kidneys. It is a hollow muscular, and distensible (or elastic) organ, and sits on the pelvic floor. Urine enters the bladder via the ureters and exits via the urethra during urination.
Urinary system: maintain fluid and electrolyte balance, purify blood and excrete liquid waste : kidneys, ureters, bladder and urethra: Integumentary system: exterior protection of body and thermal regulation: skin, hair, fat and nails: Skeletal system: structural support and protection, production of blood cells: bones, cartilage, ligaments and ...
A few white blood cells can normally be found in the urine of healthy individuals; females tend to have slightly more than males. An increased number of WBCs is termed pyuria or leukocyturia and is associated with infection or inflammation of the urinary tract. WBCs can also appear in the urine following exercise or fever.

The urinary bladder forms from the urogenital sinus. Over time, as the bladder enlarges, it absorbs the surrounding parts of the primitive ureters. [ 8 ] Finally, the entry points of the ureters into the bladder move upwards, owing to the upward migration of the kidneys in the developing embryo.
