A collective kidney, often referred to in the context of kidney function, typically describes the renal system's ability to work together as a unit, integrating various nephrons to filter blood and produce urine. However, if you are referring to a "collective kidney" in a biological or anatomical sense, it may not exist as a singular entity, as kidneys are usually individual organs. Each kidney contains numerous nephrons that collectively manage filtration and waste excretion. In research or discussions about organ systems, the term might be used metaphorically to describe the collaborative function of kidneys in maintaining homeostasis.
The organ was called a kidney first. The kidney bean is called so because it is shaped like a kidney, the organ.
An accessory kidney is an "extra" kidney.
The individual units of the kidney, called nephrons, produce urine and empty into structures called collecting ducts. Many nephrons empty into a single collecting duct. Similarly, many collecting ducts empty into a minor calyx. Minor calyces empty into a major calyx, and the major calyces empty into the singular renal pelvis (each kidney has a single pelvis). The renal pelvis empties into the ureter.
