The Urinary Bladder The bladder is an organ of the urinary system, situated anteriorly in the pelvic cavity. It is hollow, highly distensible, and rounded in shape. The main function of the bladder is the collection, temporary storage, and expulsion of urine. It has a unique muscular structure, and a complex neurological control, which shall be considered in detail. Embryologically, the bladder is derived from the hindgut. In this article, we shall look at the anatomy and physiological functions of the bladder.

Urinary Bladder The surface of the lateral and inferior sides of the urinary bladder forms a layer of loose connective tissue known as the adventitia. 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.

- Part Two: Background Information. The human urinary system consists of two kidneys, two ureters, one urinary bladder, and one urethra. This system has two basic functions, both of which occurs in the kidneys. The first function is to remove the nitrogenous wastes (such as creatine, urea, and uric acid) from the body.

Urinary System Anatomy Urination is the process of releasing urine from the urinary bladder through the urethra and out of the body. The process of urination begins when the muscles of the urethral sphincters relax, allowing urine to pass through the urethra.he kidneys filter metabolic wastes, excess ions, and chemicals from the blood to form urine. Ureters. The ureters are a pair of tubes that carry urine from the kidneys to the urinary bladder. The ureters are about 10 to 12 inches long and run on the left and right sides of the body parallel to the vertebral column.

The Urinary Tract & How It Works 1 Ureters are the thin tubes of muscle—one on each side of the bladder—that carry urine from each of the kidneys to the bladder. 2  The bladder, located in the pelvis between the pelvic bones, is a hollow, muscular, balloon-shaped organ that expands as it fills with urine.

Picture of the Bladder The bladder is lined by layers of muscle tissue that stretch to accommodate urine. The normal capacity of the bladder is 400 to 600 mL. During urination, the bladder muscles contract, 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). Bladder Conditions Cystitis: Inflammation or infection of the bladder causing acute or chronic pain or discomfort or urinary frequency or hesitancy.

Urinary bladder The urinary bladder is a hollow muscular organ that collects urine from the kidneys before disposal by urination. A hollow muscular, and distensible (or elastic) organ, the bladder sits on the pelvic floor. Urine enters the bladder via the ureters and exits via the urethra. The typical human bladder capacity is between 300 and 500 mL (10.14 and 16.91 fl oz).

Bladder Dysfunction The sympathetic nervous system regulates the process of urine storage in the bladder. In contrast, the parasympathetic nervous system controls bladder contractions and the passage of urine. The somatic efferent system permits voluntary control over the external periurethral sphincter.

Anatomy Chapter 25, 26+Endocrine+M/F Reproductive Bladder Function. Emptying is caused by stretching of the bladder which causes the PSNS to stimulate contraction of the detrusor muscle and the relaxation of the internal sphincter. SNS innervation tonically works to keep the internal sphincter contracted and the detrusor muscle relaxed as the bladder fills.

- Overview. The bladder, a hollow sac located behind the pubic bone, is an integral organ of the urinary system. The main functions of the bladder are to store urine that is produced by the kidneys and excrete it from the body.

Top 20 Doctor insights on: What Does Bladder Cancer Look Like Bladder (Definition) The bladder is a muscular organ in the pelvis that accepts urine from the kidneys, stores the urine at low pressure, & expels the urine during voluntary voiding. Though seemingly a simple reservoir, the bladder is a complex organ intricately connected with the brain and spinal cord with sensory, motor, and autonomic circuits.

Difference between Human and Frog The urinary bladder is located along the body’s midline at the inferior end of the pelvis. Urine entering the urinary bladder from the ureters slowly fills the hollow space of the bladder and stretches its elastic walls. The walls of the bladder allow it to stretch to hold anywhere from 600 to 800 milliliters of urine.

Prolapsed Bladder The bladder is a hollow organ in the pelvis that stores urine. The pressure created when the bladder fills with urine is what causes the urge to urinate. During urination, the urine travels from the bladder and out the body through the urethra. In women, the front wall of the vagina supports the bladder.

- Ureters carry urine from the kidneys to the bladder, and the bladder empties through the urethra. In the female, the bladder lies against the uterus and vagina; and in the male, against the rectum. The bladder has a moist mucosal inner lining that resists absorption, so the bladder doesn't leak urine.

How your bladder works Bladder nerves. The nerves that control your bladder can be described as follows: Parasympathetic nerves from the S2, S3 and S4 levels of your spinal cord cause the upper part of your bladder to contract and your bladder neck to relax, assisting in the process of micturition (urination).

The bladder and how it works Your bladder. Your bladder is the hollow muscular organ that stores your urine. It's a bit like a floppy balloon – as your bladder fills, it expands to store the urine. On average, your bladder can hold 400 to 600ml of urine for up to about five hours. The muscle in your bladder wall is called the detrusor muscle. The detrusor muscle relaxes to allow your bladder to fill. When you go to the toilet, it contracts to squeeze out urine.

Urinary bladder A hollow muscular, and distensible (or elastic) organ, the bladder sits on the pelvic floor. Urine enters the bladder via the ureters and exits via the urethra. There is no exact measurement for the volume of the human bladder, but different sources mention 500 mL (~17 oz) to 1000 mL (~34 oz).

Urination Main articles: Urinary bladder and Urethra. The main organs involved in urination are the urinary bladder and the urethra. The smooth muscle of the bladder, known as the detrusor, is innervated by sympathetic nervous system fibers from the lumbar spinal cord and parasympathetic fibers from the sacral spinal cord.
