X-rays usage invisible electromagnetic power beams to develop images of inner tissues, bones, and organs top top film. X-rays room made by using external radiation to develop images of the body, the organs, and also other internal structures for diagnostic purposes. X-rays pass with body tissues onto specially treated plates (similar come camera film) and a "negative" kind picture is make (the much more solid a framework is, the whiter it appears on the film). Digital films and digital media are much more commonly used now than the film media.

Other related procedures that may be provided to diagnose problems of the urinary guts of the abdomen include computed tomography (CT scan) that the kidney , kidney ultrasound , kidney scan , cystography , cystometry , cystoscopy , intravenous pyelogram , kidney biopsy , magnetic resonance imaging (MRI) , prostate ultrasound , retrograde cystography , retrograde pyelogram , uroflowmetry , and also renal venogram .


The body takes nutrients from food and converts them to energy. Afterthe body has taken the food materials that the needs, waste productsare left behind in the bowel and in the blood.

The urinary system helps the human body to eliminate liquid rubbish in theblood dubbed urea, and keeps chemicals, such as potassium and sodium,and water in balance.

Every nephron consists of a ball developed of small bloodcapillaries, dubbed a glomerulus, and also a tiny tube dubbed a renal tubule.Urea, along with water and other garbage substances, develops the urine together itpasses through the nephrons and also down the renal tubules of the kidney.

2 ureters. These narrow tubes bring urine native the kidney to the bladder. Muscle in the ureter walls continually tighten and relax forcing urine downward, far from the kidneys. If urine backs up, or is enabled to was standing still, a kidney infection can develop. About every 10 to 15 seconds, small amounts of pee are cleared into the bladder native the ureters.

Bladder. This triangle-shaped, hole organ situated in the pelvis. The is held in ar by ligaments that space attached to various other organs and also the pelvic bones.

two sphincter muscles. This circular muscles aid keep urine indigenous leaking by closing tightly favor a rubber band approximately the opening of the bladder.

Nerves in the bladder. The nerves alarm a human being when the is time come urinate, or empty the bladder.

Urethra. This tube allows urine to pass external the body. The mind signals the bladder muscles to tighten, i beg your pardon squeezes urine out of the bladder. At the exact same time, the mind signals the sphincter muscles to relax come let urine departure the bladder through the urethra. When all the signals take place in the exactly order, regular urination occurs.

Facts around urine:

adults pass about a quart and a half of urine every day, depending on the fluids and foods consumed.

The volume of urine developed at night is about half that formed in the daytime.

The tissues of the bladder space isolated native urine and also toxic building materials by a coating the discourages bacteria indigenous attaching and also growing ~ above the bladder wall.
