Urine is stored in your bladder. The bladder is the common name for the urinary bladder. It is a hollow muscular organ that stores urine before expelling it from the body. The emptying of the urinary bladder is voluntarily controlled in most human beings and many other mammals. The bladder is located just behind the pubis, which is one of the bones of the pelvis. Urine drains continuously from the kidneys into the bladder through two tubes called ureters. It leaves the bladder through the urethra, a wider tube that leads out of the body. The place where bladder and urethra meet is called the neck of the bladder. A complex arrangement of muscles encircles the bladder neck. This ring, called the urethral sphincter, normally prevents urine from leaving the bladder.
WE LOSE AROUND 3 LITERS (5 PINTS) OF WATER A DAY THROUGH OUR SKIN AS SWEAT, AND IN OUR BREATH AND URINE. WE ALSO GET RID OF EXTRA SALT IN SWEAT, AND WE EXPEL WASTE CARBON DIOXIDE GAS WHEN WE BREATHE OUT.
Working of the Urinary System
The primary function of the urinary system is to filter blood and by doing that, create urine as a waste product that expels from the body. Urinary system organs are:
- Renal pelvis
The body takes nutrients from food. After it has taken the food elements that it needs, waste products are left behind.
The urinary and kidney systems assist the body to get rid of liquid waste or urea. They also help to keep chemicals and water in balance. When foods containing protein are broken down, the waste produces urea. It carries out in the blood to the kidneys. This is where it’s removed together with water and other wastes in the form of urine.
The kidneys perform functions. It controls blood pressure and produces the hormone erythropoietin. This hormone regulates blood cell production in the bone marrow. It also conserves fluids as well as controls the acid-base balance.
Urinary system components
This pair of organs is located below the ribs. The kidneys remove urea from the blood. Their function is to:
- Remove waste products and medications from the body
- Balance the fluids of the body
- Balance a variety of electrolytes
- Release hormones to control blood pressure
- Release a hormone
- Help by controlling calcium in bone
They are tubes that carry urine from the kidneys into the bladder. Muscles in the ureter walls maintain relaxing and tightening. This forces urine downward away from the uterus. If urine backs up or is permitted to stand still, a kidney infection can develop.
This is a triangle-shaped, hollow organ that can be found in the lower abdomen part of the body. It is attached to ligaments that are connected to the pelvic bones. The bladder contract and flatten, which lets urine out of the body through the urethra. A healthy adult’s bladder can store up to two cups of urine for 2 to 5 hours.
These round muscles keep urine from leaking by closing tightly like a rubber band around the bladder’s opening.
This squeezes urine from the bladder. In this, the brain also signals the sphincter muscles to relax in order to let the urine exit the bladder through the urethra. When all the signs happen in the correct order, normal urination occurs.
