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.
The key â¦ components of the urinary (excretory) system are: Two kidneys which filter water-soluble waste from the bloodTwo ureters which send the urine from the kidneys to the bladderThe bladder which collects urine before it is expelled from the bodyThe urethra which is a tube connecting the bladder to the genitalsTwo sphincter muscles which allow for regulation and control of the excretion process
