What is function of urinary bladder?
Is bladder on left or right?
The bladder sits in the center of the pelvis. If a person feels pain in the lower right or left abdomen, it is less likely to relate to the bladder and may signal kidney stones instead.
What is the structure of the urinary bladder?
Bladder. This triangle-shaped, hollow organ is located in the lower abdomen. It is held in place by ligaments that are attached to other organs and the pelvic bones. The bladder's walls relax and expand to store urine, and contract and flatten to empty urine through the urethra.
How do I know if my bladder has a problem?

What is the size of urinary bladder?
This stretching can increase the size of the bladder from about 2 inches to more than 6 inches long, depending on the amount of liquid. The typical human bladder reaches its capacity between 16 to 24 ounces of urine, but the urge to urinate comes when the bladder is about one-quarter full.
Is urinating every 2 hours normal?
It's considered normal to have to urinate about six to eight times in a 24-hour period. If you're going more often than that, it could simply mean that you may be drinking too much fluid or consuming too much caffeine, which is a diuretic and flushes liquids out of the body.

Can your bladder repair itself?
The bladder is a master at self-repair. When damaged by infection or injury, the organ can mend itself quickly, calling upon specialized cells in its lining to repair tissue and restore a barrier against harmful materials concentrated in urine.
What are the symptoms of an inflamed bladder?
Bladder infections can lead to inflammation of the bladder (cystitis). Symptoms include pain and burning with urination, increased frequency of urination and sometimes abdominal pain. The inflammation usually improves after a course of antibiotics.

What is the base of the bladder?
The fundus is the base of the bladder, which is formed by the posterior wall and contains the trigone of the bladder, and is lymphatically drained by the external iliac lymph nodes. The trigone is the structure that contains the outlet (urethra) of the bladder.
Where is the bladder located?
Generally, the bladder is a hollow, muscular, and pear-shaped distensible elastic organ that sits on the pelvic floor. It receives urine via the ureters, which are thick tubes running from each kidney down to the superior part of the bladder.
Why do babies have incontinence?
Problems with the muscles of the urinary bladder or sphincters can lead to incontinence (involuntary urination). In babies, the nervous system has not yet developed further, so a baby's bladder fills to a set point, then automatically contracts and empties. As the child matures, so does the nervous system, which means the brain can now receive messages from the filling bladder and prevent it from automatically emptying until convenient. Failures in this control mechanism results in incontinence, but there are many different ways that lead to mechanism failure (e.g. neurologic injury, congenital defects, strokes, multiple sclerosis, and aging).
What nerves control urination?
To control the act of urination voluntarily, motor control is achieved through innervation by both sympathetic fibers, most of which arise from the hypogastric plexuses and nerves, and parasympathetic fibers, which come from the pelvic splanchnic nerves and the inferior hypogastric plexus.
Which organ collects urine?
The urinary bladder is an organ that serves to collect urine to be voided through urination after the urine is filtered through the kidneys (where the necessary ions are reabsorbed if physiologically needed through feedback mechanisms found throughout the body and in the nephrons of the kidneys, such as the macula densa).
What is the relationship between the ureters and the uterine arteries?
This phrase describes an anatomical relationship, between the ureters and the uterine arteries (female) or the vas deferens (males). During a hysterectomy, where the uterus and uterine artery are removed, the ureter is in danger of being accidentally damaged.
Where do GVA fibers follow?
Whereas GVA fibers on the superior surface of the bladder follow the course of the sympathetic effect nerves back to the CNS, GVA fibers on the inferior portion follow along with the parasympathetic efferent fibers.
What is the function of the urinary bladder?
The urinary bladder and urethra are pelvic urinary organs whose respective functions are to store and expel urine outside of the body in the act of micturition (urination). As is the case with most of the pelvic viscera, there are differences between male and female anatomy of the urinary bladder and urethra.
Where is the urinary bladder located?
Location. The urinary bladder is found inferior to the peritoneum, sitting on the pelvic floor. In females its inferior surface lays on the pubic symphysis and the posterior wall is in contact with the vagina and uterus.
What muscle is responsible for the urethral sphincter?
The detrusor muscle comprises the wall of the urinary bladder. It forms the internal urethral sphincter around the neck of the bladder. The detrusor muscle contracts around the ureteric orifices when the bladder contracts in order to prevent vesicoureteral reflux (backflow of urine into the ureters).
What is the name of the organ that stores urine?
Urinary bladder. The urinary bladder is a hollow muscular organ. It temporarily stores urine conveyed by the ureters from the kidneys until the body is ready to expel it through the urethra. Male urinary bladder: Diagram.
What is the meaning of the term "urinary bladder"?
Key facts about the urinary bladder and urethra. Urinary bladder. Definition: a hollow organ which collects the urine. Blood supply: superior and inferior vesical arteries (in men), vesical and vaginal arteries (in women); vesical venous plexus. Innervation: inferior hypogastric plexus.
Where does the urethra go?
Membranous urethra passes through the deep perineal pouch where it is surrounded by the external urethral sphincter. Spongy (penile) urethra travels through the corpus spongiosum of the penis. The urethra opens through the external urethral orifice (urethral meatus) at the top of the glans. Penis Explore study unit.
How long is the male urethra?
The male urethra is much longer (20 centimeters). It has four parts: Preprostatic (intramural) urethra which extends from the internal urethral orifice to the prostate. Prostatic urethra penetrates the prostate in which it is joined by the ejaculatory duct of the male reproductive system .
Where is the urinary bladder located?
All rights reserved. Prev. Next. The urinary bladder is a muscular sac in the pelvis, just above and behind the pubic bone. When empty, the bladder is about the size and shape of a pear. Urine is made in the kidneys and travels down two tubes called ureters to the bladder. The bladder stores urine, allowing urination to be infrequent and controlled.
What is the normal capacity of the bladder?
The bladder is lined by layers of muscle tissue that stretch to hold urine. The normal capacity of the bladder is 400-600 mL. During urination, the bladder muscles squeeze, and two sphincters (valves) open to allow urine to flow out.
What is the sphincter that allows urine to flow out of the body?
During urination, the bladder muscles squeeze, and two sphincters (valves) open to allow urine to flow out. Urine exits the bladder into the urethra, which carries urine out of the body. Because it passes through the penis, the urethra is longer in men (8 inches) than in women (1.5 inches).
Why does urine not exit the bladder?
Urinary retention: Urine does not exit the bladder normally due to a blockage or suppressed bladder muscle activity. The bladder may swell to hold more than a quart of urine. Cystocele: Weakened pelvic muscles (usually from childbirth) allow the bladder to press on the vagina. Problems with urination can result.
How to treat bladder cancer?
Bladder Treatments. Cystoscopy: A narrow tube is passed through the urethra into the bladder. A light, camera, and tools allow a doctor to diagnose and treat bladder problems. Surgery: Bladder cancer generally requires surgery. Some cases of urinary incontinence and cystocele may also be treated with surgery.
What causes pain in the bladder?
Cystitis: Inflammation or infection of the bladder causing acute or chronic pain, discomfort, or urinary frequency or hesitancy. Urinary stones: Stones (calculi) may form in the kidney and travel down to the bladder. If kidney stones block urine flow to or from the bladder, they can cause severe pain.
Why does my urine leak out?
Urinary incontinence can result from many causes. Overactive bladder: The bladder muscle (detrusor) squeezes uncontrollably, causing some urine to leak out. Detrusor overactivity is a common cause of urinary incontinence. Hematuria: Blood in the urine.
What is the role of the bladder in the urinary system?
6 Clinical Relevance: Urine Retention. The bladder is an organ of the urinary system. It plays two main roles: Temporary storage of urine – the bladder is a hollow organ with distensible walls. It has a folded internal lining (known as rugae), which allows it to accommodate up to 400-600ml of urine in healthy adults.
What are the functions of the bladder?
The bladder is an organ of the urinary system. It plays two main roles: 1 Temporary storage of urine – the bladder is a hollow organ with distensible walls. It has a folded internal lining (known as rugae), which allows it to accommodate up to 400-600ml of urine in healthy adults. 2 Assists in the expulsion of urine – the musculature of the bladder contracts during micturition, with concomitant relaxation of the sphincters.
What is the bladder stretch reflex?
The bladder stretch reflex is a primitive spinal reflex, in which micturition is stimulated in response to stretch of the bladder wall. It is analogous to a muscle spinal reflex, such as the patella reflex.
What does the bladder look like when empty?
The appearance of the bladder varies depending on the amount of urine stored. When full, it exhibits an oval shape , and when empty it is flattened by the overlying bowel.
What is the shape of the bladder when it is full?
When full, it exhibits an oval shape, and when empty it is flattened by the overlying bowel. The external features of the bladder are: Apex - located superiorly, pointing towards the pubic symphysis. It is connected to the umbilicus by the median umbilical ligament (a remnant of the urachus).
Why is my bladder emptying?
In males, the most common cause is obstruction due to prostate enlargement (BPH). Other causes include obstruction by a stone or large blood clot.
Where are the bladder stretch reflexes located?
They are found in the bladder wall and signal the need to urinate when the bladder becomes full. The Bladder Stretch Reflex. The bladder stretch reflex is a primitive spinal reflex, in which micturition is stimulated in response to stretch of the bladder wall.
What is the bladder?
The bladder, like the stomach, is an expandable saclike organ that contracts when it is empty. The inner lining of the bladder tucks into the folds and expands out to accommodate liquid.
Where does the bladder release urine?
When signaled, the bladder releases urine through the urethra, the tube that carries urine out of the body. In women, this tube ends between the clitoris and the vagina. Healthy bladders hold urine until people have time to relieve themselves, but problems can arise for varying reasons.
What is the function of the bladder sphincter?
An internal sphincter — a type of muscular valve — helps prevent urine from leaking out. The triangle-shaped base of the bladder, known as the trigone, helps prevent stretching of the urethra or backflow into the ureters. When signaled, the bladder releases urine through the urethra, the tube that carries urine out of the body.
How long is the bladder when stretched?
This stretching can increase the size of the bladder from about 2 inches to more than 6 inches long , depending on the amount of liquid.
Why are bladder infections more common in women?
Bladder infections and infections of the urinary tract are more common in women as the location and length of their urethra makes them more prone to outside bacteria than men. Also, women who have recently given birth may experience urinary problems. Bladder control issues are common in women over the age of 50.
What is the urinary system?
