Doctors can often see a large hiatus hernia on a chest x-ray. Otherwise, people are given barium in a liquid before x-rays are taken (barium swallow). The barium outlines the esophagus, making abnormalities easier to see. Hernias can also be seen during an upper endoscopy.
The kidneys filter the blood to remove wastes and produce urine. The ureters, urinary bladder, and urethra together form the urinary tract, which acts as a plumbing system to drain urine from the kidneys, store it, and then release it during urination.
Human body has two kidneys, which are the prime organs of the urinary system and function to excrete most of the waste products of metabolism. The waste products are formed into urine, which leaves the kidney by passing down the ureters to the urinary bladder, from where it is expelled out of the body through urethra.he waste products are formed into urine, which leaves the kidney by passing down the ureters to the urinary bladder, from where it is expelled out of the body through urethra.
