Medical Language, Second Edition Susan Turley Anatomy of the Urinary System Ureters –12-inch tube that connects the renal pelvis of the kidney to the bladder. –The ureteral orifices are the openings into the bladder. –Composed of smooth muscle
Copyright ©2011 by Pearson Education, Inc. Upper Saddle River, New Jersey All rights reserved. Medical Language, Second Edition Susan Turley Anatomy of the Urinary System Bladder –Located in the pelvic cavity and held in place by ligaments –Fundus: Rounded top of bladder –Inside of bladder is lined with mucosa –When bladder is empty, the mucosa collapses into folds, or rugae. –When bladder is full, smooth muscle in the bladder wall contracts to expel urine.

Medical Language, Second Edition Susan Turley Anatomy of the Urinary System Urethra –A tube that carries urine from the bladder to the outside of the body. –External urethral sphincter is a muscular ring that can be consciously controlled to release or hold back urine.
Copyright ©2011 by Pearson Education, Inc. Upper Saddle River, New Jersey All rights reserved. Medical Language, Second Edition Susan Turley Anatomy of the Urinary System (cont’d) –In men, the urethra is 7 to 8 inches long. –The urethra is part of both the urinary and the male reproductive system, because it transports both urine and semen. In women, the urethra is much shorter, traveling only 1 to 2 inches from the bladder to the external surface of the body.

Copyright ©2011 by Pearson Education, Inc. Upper Saddle River, New Jersey All rights reserved. Medical Language, Second Edition Susan Turley Physiology of the Formation of Urine The nephron, a microscopic structure, is the functional unit of the kidney and the site of urine production. The first part of the nephron is the glomerular capsule.
Copyright ©2011 by Pearson Education, Inc. Upper Saddle River, New Jersey All rights reserved. Medical Language, Second Edition Susan Turley Physiology of the Formation of Urine (cont’d) Within this ball-shaped structure, the arteriole divides and forms the glomerulus, a network of intertwining capillaries. Waste products in the blood include: –Urea –Creatinine –Uric acid –Drugs and products of drug metabolism
Copyright ©2011 by Pearson Education, Inc. Upper Saddle River, New Jersey All rights reserved. Medical Language, Second Edition Susan Turley The blood that enters the nephron also contains: –Electrolytes –Glucose –Amino acids –Vitamins Physiology of the Formation of Urine (cont’d)
Copyright ©2011 by Pearson Education, Inc. Upper Saddle River, New Jersey All rights reserved. Medical Language, Second Edition Susan Turley The job of the nephron is to remove the waste products from the blood but keep the nutritional substances. This process is known as filtration. Physiology of the Formation of Urine (cont’d)
Copyright ©2011 by Pearson Education, Inc. Upper Saddle River, New Jersey All rights reserved. Medical Language, Second Edition Susan Turley The filtrate (waste products, water, and nutritional substances) flows into the proximal convoluted tubule of the nephron. Most of the water and nutritional substances move out of the tubule and return to the blood. This process is known as reabsorption. Physiology of the Formation of Urine (cont’d)
Copyright ©2011 by Pearson Education, Inc. Upper Saddle River, New Jersey All rights reserved. Medical Language, Second Edition Susan Turley The proximal convoluted tubule becomes a U-shaped tubule known as the nephron loop. In the nephron loop, more water and electrolytes are reabsorbed. Physiology of the Formation of Urine (cont’d)
Copyright ©2011 by Pearson Education, Inc. Upper Saddle River, New Jersey All rights reserved. Medical Language, Second Edition Susan Turley Physiology of the Formation of Urine (cont’d) The nephron loop widens to become the distal convoluted tubule where more water and electrolytes, as well as amino acids and other nutritional substances, are reabsorbed. Urine is produced continuously by the nephrons in the kidneys.

Copyright ©2011 by Pearson Education, Inc. Upper Saddle River, New Jersey All rights reserved. Medical Language, Second Edition Susan Turley The process of eliminating urine from the body is described in several ways: –Urination –Micturition –Voiding –Passing water Physiology of the Formation of Urine (cont’d)
Copyright ©2011 by Pearson Education, Inc. Upper Saddle River, New Jersey All rights reserved. Medical Language, Second Edition Susan Turley Physiology of Other Functions of the Kidneys Besides producing and excreting urine, the kidneys also help the body to maintain a normal and constant internal environment. The kidneys respond if blood pressure decreases, if the pH of the blood decreases, or if the number of red blood cells decreases.
