Isotopes when written out are common nouns, and should begin with the uncapitalized element name, followed by a hyphen (not an em dash or en dash) and then the mass number. Examples are carbon-14 and uranium-235.
The central region of the kidney contains the renal pelvis, which is located in the renal sinus, and is continuous with the ureter. The renal pelvis is a large cavity that collects the urine as it is produced. The periphery of the renal pelvis is interrupted by cuplike projections called calyces.
The major calices then converge into a funnel-like cavity called the renal pelvis. The renal pelvis, which is attached to the indented side of the kidney anatomy (hilum), extends into the ureter. The ureter is a long narrow duct (tube) that conveys urine from the kidneys to the urinary bladder.idney anatomy encompasses all the tissue-components that collectively form the structure of the kidney. Most humans are born with two kidneys, although one kidney is capable of performing the normal functions of both kidneys. Some people are born with one kidney.
