how our organs work
Liver: converts impurities and poisons in the body to less harmful substances. For example,the liver forms urea from a harmful waste product of protein breakdown.
Urea: a colorless crystalline compound that is the main nitrogenous breakdown product of protein metabolism in mammals and is excreted in urine.
Lungs and skin: when you exhale your lungs release carbon dioxide and water from your body, skin releases toxins through sweat.
Kidneys: filters urea and other wastes from the blood
Kidney stones: salt, calcium stones that block urine from flowing

Cortex: outer area of kidney
Medulla: inside, is composed of seven cone shaped renal pyramids
Renal pyramids: make up medulla, (only 3 of them are shown in the image) with the tubes visible from them making up a collection of nephrons. The renal pyramids merge to form the renal pelvis
Renal pelvis: at the center of the kidney, urine collects here before
draining into the ureter
Ureter: tubes, travelling to the bladder for storage.
Nephron: complex structure composed of many tubes, and each kidney has about 1 million nephrons.
Tubular reabsorption, cells in the proximal tubule remove water and nutrients from the filtrate and pass them back into the blood, wastes such as urea are retained in the tubule. During tubular secretion, wastes that were not initially filtered out in the bowman's capsule are removed from
