Nephrons
When each cell specializes in a certain task: some cells make fingernails, others become blood cells, brain cells, kidney cells, etc.

The urea and water that make up urine are removed from the blood in the kidney. This is then passed on to the bladder which will be excreted as urine.
Solid wastes are defined as any type of municipal or industrial waste that needs to be disposed of. Hazardous wastes are defined by characteristic codes and listed ingredients that make up the substance to be disposed of.
Water is the biggest "substance" in making blood. Blood is about 97% water.
Kidneys play a main role in filtering liquid wastes from our body. Kidney has millions of nephrons which filter the urine. it removes urea, other toxic materials from it. and by chance if glucose and other useful products are removed then they are reabsorbed in final filtration process. nephron is the simplest unit of kidney.kidneykidneysThe kidney.Kidneykidneys
Red bone marrow.
It regulates the levels of some chemicals, the main ones being sodium, phosphorous and potassium. It also secretes three important hormones: - Epo (erythropoietin) which tells bone marrow to make red blood cells - Calcitriol - the active from of Vit D, which helps maintain optimum calcium levels - Renin, which regulates blood pressure

The kidneys filter the blood to produce urine
Kidney stones occur when crystals form inside the kidney. They begin microscopically small, and grow over time. Most stones are passed as tiny grains of sand, while others may grow as large as a Golf ball or more, or look like the horns of a moose (staghorn kidney stones). There are many reasons some people develop kidney stones. Medications can cause the development of some types of stones, as can some illnesses. The congenital condition medullary sponge kidney disease often results in stones formed so frequently that passing them is almost a daily occurrence. Most stones are the result of a metabolic imbalance. Sometimes the metabolic imbalance can be treated, sometimes it can't. A common way to treat patients for recurrent kidney stones is potassium citrate, which makes it less likely for certain stones to form inside the kidney. Some stones are the result of an imbalanced diet which may be easily altered without medication to help.
The circulatory system moves material around the body and the urinary system dumps wastes from your body, these wastes can poison your body and your body would not live for long without it. They work together when the circulatory system moves food and oxygen to each cell and them takes away the cells' wastes. When the circulatory system reaches the urinary system it releases the wastes and the urinary system drops the wastes from the body.
The symptoms include blood in urine, pain when urinating and sharp pains in the lower abdomen and back. If kidney stones are suspected, it is important to see a specialist ASAP as there are procedures which can make passing the kidney stones less painful.
