what is the main function of the urinary bladder?
5003
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.

According to Focus Magazine, the average human bladder can hold about 400 to 600 milliliters of urine. The average person produces about 1,500 ml of urine every 24 hours, so it only takes nine or 10 hours before you're filled up and you've gotta go — bad.

Structure and Function The internal urethral sphincter regulates involuntary control of urine flow from the bladder to the urethra, and the external urethral sphincter provides voluntary control of urine flow from the bladder to the urethra.

A healthy adult bladder can hold up to 16 ounces (2 cups) of urine comfortably, according to the National Institutes of Health. How frequently it fills depends on how much excess water your body is trying to get rid of. Circular muscles called sphincters close tightly to keep urine from leaking.

Introduction to the Female Urogenital System When urine is formed, tubes called ureters transport it to the urinary bladder, where it is stored and excreted via the urethra. The uterus or womb is the major female reproductive organ, which supports and nourishes the developing baby.

Physiologically, micturition involves the coordination of the central, autonomic, and somatic nervous systems. The brain centers that regulate urination include the pontine micturition center, the periaqueductal gray, and the cerebral cortex, which cause both involuntary and voluntary control over micturition.

The primary function of nephron is removing all waste products including the solid wastes, and other excess water from the blood, converting blood into the urine, reabsorption, secretion, and excretion of numerous substances.

The urinary system, also known as the renal system, produces, stores and eliminates urine, the fluid waste excreted by the kidneys. The kidneys make urine by filtering wastes and extra water from blood. Urine travels from the kidneys through two thin tubes called ureters and fills the bladder.

Most people know that a major function of the kidneys is to remove waste products and excess fluid from the body. These waste products and excess fluid are removed through the urine. The production of urine involves highly complex steps of excretion and re-absorption.

A healthy human bladder can hold between 400 to 500 milliliters of urine, or about 2 cups, before it reaches capacity. Though a healthy bladder can stretch and accommodate larger volumes of urine, it's important to urinate at regular intervals.

The detrusor muscle is located within the walls of the bladder and is composed of smooth muscle fibers that are longitudinal and circular.

A cystometric test measures how much urine the bladder can hold, how much pressure builds up inside the bladder as it stores urine, and how full it is when the urge to urinate begins. A catheter is used to empty the bladder completely. Then a special, smaller catheter is placed in the bladder.

Your bladder relies on muscles to contract and release when you're ready to urinate. Your brain typically regulates this process, but sometimes the message that you need to urinate isn't sent from your brain to your bladder. This is a condition known as neurogenic bladder.
