How does the bladder work?
In humans the bladder is a hollow distensible organ that sits on the pelvic floor. Urine enters the bladder via the ureters and exits via the urethra. The typical human bladder will hold between 300 and 500 ml (10.14 and 16.91 fl oz) before the urge to empty occurs, but can hold considerably more.
How many openings does the bladder have?
The bladder has three openings. The two ureters enter the bladder at ureteric orifices, and the urethra enters at the trigone of the bladder. These ureteric openings have mucosal flaps in front of them that act as valves in preventing the backflow of urine into the ureters, known as vesicoureteral reflux. Between the two ureteric openings is a raised area of tissue called the interureteric crest. This makes the upper boundary of the trigone. The trigone is an area of smooth muscle that forms the floor of the bladder above the urethra. It is an area of smooth tissue for the easy flow of urine into and from this part of the bladder - in contrast to the irregular surface formed by the rugae.

Why do amphibians have a high rate of urine production?
As a result, they tend to have high rates of urine production to offset this high water intake , and have urine which is low in dissolved salts. The urinary bladder assists such animals to retain salts. Some aquatic amphibian such as Xenopus do not reabsorb water, to prevent excessive water influx. For land-dwelling amphibians, dehydration results in reduced urine output.
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 function of the urinary bladder?
Prior to urination, it stores urine produced and delivered by the kidneys through two ureters. The human urinary bladder is hollow, muscular, and can hold up to four cups of urine.
Why does the bladder hold urine?
The bladder can hold a considerable amount of urine, which allows the kidneys the ability to continue filtering the blood even when an organism cannot urine. For example, during sleep, the bladder must store extra urine. This allows an organism to rest without needing to urinate.
What are bladder stones?
Bladder stones are hard deposits composed of minerals found in the bladder caused by dehydration and highly concentrated urine residing in the bladder. Stones can vary in size and are typically asymptomatic. Common symptoms are typically pain, blood in the urine, and irritation.
What is the most common cause of urinary tract infections?
These infections are caused by bacterial infections in the bladder, usually caused by bacteria traveling up the urethra and into the bladder. When left untreated, UTIs can be very dangerous, as the infection can progress from the bladder into the kidneys. Common symptoms include a burning sensation during urination, cloudy and/or foul-smelling urine, and the frequent urge to urinate, despite little urine being released.
What is the term for the protrusion of the bladder through the wall of the abdomen?
Bladder Exstrophy. Bladder exstrophy is a congenital abnormality which involves the protrusion of the bladder through the wall of the abdomen. This condition is extremely rare and is often accompanied by the abnormal development of the pelvic floor and other muscles, as well as the genitals, especially in women.
Why does my bladder stop urinating?
This disorder is caused by a sympathetic nervous system response which tightens the sphincters in the bladder in response to adrenaline, thereby preventing urination . Typically, treating this condition requires psychological therapy.
What is the condition where you need to urinate?
Trigonitis is a condition involving inflammation of the trigone region of the bladder. In particular, the trigone is a smooth triangular-shaped region and signals the need for urination in response to stretching. An inflammation of this region can result in an urgent need to urinate, pain in the pelvic region, and pain or difficulty urinating. Although there are several causes of trigonitis, bladder infections are the most common etiology.

Where is the urinary bladder located?
It is located in the pelvic cavity anterior to the rectum and superior to the reproductive organs of the pelvis. In females the urinary bladder is somewhat reduced in size and must share the limited space of the pelvic cavity with the uterus that rests superior and posterior to it.
What is the innermost layer of the bladder?
The innermost layer of the bladder is the mucosa layer that lines the hollow lumen. Unlike the mucosa of other hollow organs, the urinary bladder is lined with transitional epithelial tissue that is able to stretch significantly to accommodate large volumes of urine.
What organ is responsible for storing urine?
The adventitia loosely connects the urinary bladder to the surrounding tissues of the pelvis. The urinary bladder functions as a storage vessel for urine to delay the frequency of urination. It is one of the most elastic organs of the body and is able to increase its volume greatly to accommodate between 600 to 800 ml of urine at maximum capacity.
What are the layers of the bladder?
The urinary bladder is made of several distinct tissue layers: 1 The innermost layer of the bladder is the mucosa layer that lines the hollow lumen. Unlike the mucosa of other hollow organs, the urinary bladder is lined with transitional epithelial tissue that is able to stretch significantly to accommodate large volumes of urine. The transitional epithelium also provides protection to the underlying tissues from acidic or alkaline urine. 2 Surrounding the mucosal layer is the submucosa, a layer of connective tissue with blood vessels and nervous tissue that supports and controls the surrounding tissue layers. 3 The visceral muscles of the muscularis layer surround the submucosa and provide the urinary bladder with its ability to expand and contract. The muscularis is commonly referred to as the detrusor muscle and contracts during urination to expel urine from the body. The muscularis also forms the internal urethral sphincter, a ring of muscle that surrounds the urethral opening and holds urine in the urinary bladde. During urination, the sphincter relaxes to allow urine to flow into the urethra.
What is the tube that carries urine out of the body?
A small funnel forms at the inferior end of the urinary bladder leading into the urethra, the tube that carries urine out of the body during urination. The urinary bladder is made of several distinct tissue layers: The innermost layer of the bladder is the mucosa layer that lines the hollow lumen.

What are the wrinkles on the bladder?
During pregnancy the uterus takes up significantly more space and severely limits the expansion of the urinary bladder. Many tiny wrinkles, known as rugae, line the inner surface of the urinary bladder and allow it to stretch as it fills with urine.
Where is the urinary bladder located?
The urinary bladder is a hollow, collapsible muscular sac that stores and expels urine situated in the pelvic cavity posterior to the pubic symphysis. In males, it is. directly anterior to the rectum; in females, it is anterior to the vagina and inferior to the uterus (see Figure 1). Folds of the peritoneum hold the urinary bladder in position.
What is the floor of the urinary bladder?
In the floor of the urinary bladder is a small triangular area called the trigone. The two posterior corners of the trigone contain the two ureteral openings; the opening into the urethra, the internal urethral orifice, lies in the anterior corner (see Figure 2). Because its mucosa is firmly bound to the muscularis, the trigone has a smooth appearance. Three coats make up the wall of the urinary bladder. The deepest is the mucosa, a mucous membrane composed of transitional epithelium and an underlying lamina propria similar to that of the ureters. The transitional epithelium permits stretching. Rugae (the folds in the mucosa) are also present to permit expansion of the urinary bladder. Surrounding the mucosa is the intermediate muscularis, also called the detrusor muscle (to push down),#N#which consists of three layers of smooth muscle fibers: the inner longitudinal, middle circular, and outer longitudinal layers. Around the opening to the urethra the circular fibers form an internal urethral sphincter; inferior to it is the external urethral sphincter, which is composed of skeletal muscle and is a modification of the deep muscles of the perineum. The most superficial coat of the urinary bladder on the posterior and inferior surfaces is the adventitia, a layer of areolar connective tissue that is continuous with that of the ureters. Over the superior surface of the urinary bladder is the serosa, a layer of visceral peritoneum.
What happens when you urinate before the micturition reflex?
Urinary bladder filling causes a sensation of fullness that initiates a conscious desire to urinate before the micturition reflex actually occurs.
Why does my bladder contract too much?
The bladder muscle may contract too much or not enough because of a problem with the muscle itself or the nerves controlling the bladder muscle. Damage to the sphincter muscles themselves or the nerves controlling these muscles can result in poor sphincter function. These problems can range from simple to complex.
Why is the bladder smaller in females?
Urinary bladder capacity averages 700–800 mL. It is smaller in females because the uterus occupies the space just superior to the urinary bladder.
Why does my bladder not empty?
When the bladder doesn’t empty properly, urine spills over, causing overflow incontinence. Weak bladder muscles or a blocked urethra can cause this type of incontinence. Nerve damage from diabetes or other diseases can lead to weak bladder muscles; tumors and urinary stones can block the urethra.
What is the most superficial layer of the urinary bladder?
The most superficial coat of the urinary bladder on the posterior and inferior surfaces is the adventitia, a layer of areolar connective tissue that is continuous with that of the ureters. Over the superior surface of the urinary bladder is the serosa, a layer of visceral peritoneum. Figure 1. Urinary bladder location.

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.
How many ml of urine does the bladder hold?
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. Urine exits the bladder into the urethra, which carries urine out of the body.

Overview
The urinary bladder, or simply bladder, is a hollow organ in humans and other vertebrates that stores urine from the kidneys before disposal by urination. In humans the bladder is a distensible organ that sits on the pelvic floor. Urine enters the bladder via the ureters and exits via the urethra. The typical human bladder will hold between 300 and 500 ml (10.14 and 16.91 fl oz) before the urge to empty occurs, but can hold considerably more.
Structure
In humans, the bladder is a hollow muscular organ situated at the base of the pelvis. In gross anatomy, the bladder can be divided into a broad fundus, a body, an apex, and a neck. The apex is directed forward toward the upper part of the pubic symphysis, and from there the median umbilical ligament continues upward on the back of the anterior abdominal wall to the umbilicus. The peritoneum is carried by it from the apex on to the abdominal wall to form the middle umbilica…
Function
Urine, excreted by the kidneys, collects in the bladder because of drainage from two ureters, before disposal by urination (micturition). Urine leaves the bladder via the urethra, a single muscular tube ending in an opening called the urinary meatus, where it exits the body. Urination involves coordinated muscle changes involving a reflex based in the spine, with higher inputs from the brain. During urination, the detrusor muscle contracts, and the external urinary sphincter and mu…
Clinical significance
Cystitis refers to infection or inflammation of the bladder. It commonly occurs as part of a urinary tract infection. In adults, it is more common in women than men, owing to a shorter urethra. It is common in males during childhood, and in older men where an enlarged prostate may cause urinary retention. Other risk factors include other causes of blockage or narrowing, such as prostate cancer or the presence of vesico-ureteric reflux; the presence of outside structures in th…
Other animals
All mammals have a urinary bladder. This structure begins as an embryonic cloaca. In the vast majority, this eventually becomes differentiated into a dorsal part connected to the intestine and a ventral part which becomes associated with the urinogenital passage and urinary bladder. The only mammals in which this does not take place are the platypus and the spiny anteater both of which retain the cloaca into adulthood.
