3. The urinary system (also called the urinary tract or renal system) is one of the systems our bodies use to get rid of waste products. The urinary system refers to the structures that produce and conduct urine to the point of excretion. URINARY SYSTEM ORGAN Kidneys (2) Ureters (2) Urinary bladder Urethra The kidneys, ureters, bladder, and urethra are the primary structures of the urinary system. They filter blood and remove waste from the body in the form of urine. The size and position of lower urinary structures vary with male and female anatomy..

Kidneys (2). The human body has two bean shaped organs called kidneys, one on either side of the middle back, just under the ribs. Each kidney contains thousands of small filters called nephrons. Each nephron has a mesh of capillaries, connecting it to the body’s blood supply. Around 180 liters of blood sieve through the kidneys every day. The main functions of the kidney include: Regulating the amount of water and salts in the blood Filtering out waste products Making a hormone that helps to control blood pressure. Kidneys Filter Blood at the Top of the Urinary System.The kidneys are key players in the urinary tract. You need at least one working kidney to be healthy..

Ureters(2). (pronounced: YUR-uh-ters). 5. Each kidney has a tube called a ureter. The filtered waste products (urine) leave the kidneys via the ureters and enter the bladder. The Ureters Move Urine from the Kidneys to the Bladder.

The bladder is a hollow organ that sits inside the pelvis. It stores the urine. When a certain amount of urine is inside the bladder, the bladder ‘signals’ the urge to urinate. Urine contains water and waste products like urea and ammonia. Urine flows through the ureters into the urinary bladder. In women, the bladder is located in front of the vagina and below the uterus. In men, the bladder sits in front of the rectum and above the prostate gland. The wall of the bladder contains folds called rugae, and a layer of smooth muscle called the detrusor muscle. As urine fills the bladder, the rugae smooth out to accommodate the volume. The detrusor relaxes to hold the urine, then contracts for urination. An adult bladder is full at about half a liter, or about two cups..

[Virtual Presenter] Urinalysis (method for diagnosing urinary tract disorders) Kidney stones - caused by infection and high blood levels of calcium. Bladder cancer Kidney Cancer Benign prostatic hypertrophy Diabetes Bladder infections - (cystitis) usually caused by bacteria Urinary tract infection Prostatitis Urethritis (inflammation of the urethra, associated with gonorrhea and chlamydial) Interstitial cystitis Kidney infections - when a bladder infection ‘backs up’ the ureters. Bladder prolapse Enlarged prostate - in men, this can make it difficult to empty the bladder. Incontinence – when urine leaks out of the urethra.

Red Blood Cells. 9. Infections. Organisms that infect the urinary tract generally enter through the urethra and ascend toward the bladder, producing cystitis. Untreated, the infection can ascend even further into the urinary tract. The infecting organisms are usually colon bacteria carried in feces, particularly e-coli. Although urinary tract infections (UTIs) do occur in men, they appear more commonly in women because the female urethra is shorter than the male urethra and its opening is closer to the anus. Poor toilet habits and urinary stasis are contributing factors..

10. Cancer. Carcinoma of the bladder (bladder cancer) has been linked to occupational exposure to chemicals, parasitic infections, and cigarette smoking. A key symptom is sudden, painless hematuria. Often, the cancer can be seen by viewing the bladder lining with a cystoscope. This instrument can also be used to biopsy tissue for study. If treatment is not effective in permanently removing the tumor, a cystectomy (removal of the bladder) may be necessary Cancer may also involve the kidney and renal pelvis. Additional means for diagnosing cancer and other urinary tract disorders include ultrasound, computed tomography scans, and radiographic studies.
