A circulatory system (cardiovascular system in biology classes) is an organ system that moves substances to and from cells; it can also help stabilize body temperature and pH (part of homeostasis). There are three types of circulatory systems (from simplest to most complex): no circulatory system, open circulatory system, and closed circulatory system.\n\nYou could get more information from the link below...

cell-tissue-organ-organ systems-organism (population)\nTissues are a group of specialized cells that perform a function. Organs are groups of specialized tissues that perform an even more complex function. Organ systems are groups of organs that perform a function in a series of complex, yet related steps. An organism is a body with  several organ systems necessary to maintain homeostasis. This can be extended to population which is several organisms existing together to survive (think food webs).\n\nUnicellular organisms do not have specialized cells. They have only one cell to perform all the functions it needs.

1.- cleanses your system, your kidneys, that's why\nyou urinate.\n\nYou take things in, through the nose by breathing, the mouth by eating, etcetera. Your body needs water and other fluids to process this through your kidneys and clean your body out.\n\n2.- moisturizes the tissues within your body, makes them function adequately. For example the immunological system. The cells and antibodies require to synapse, and this requires energy, one of which the carriers for is water.

Back pain is often associated with the kidneys.  Your kidneys are located near your back, alongside your spine, but above your waistline. Each kidney contains over a million nephrons. These nephrons are necessary for proper kidney function.   Nephrotoxicity, one of the most common kidney problems, occurs when your body is exposed to a drug or toxin that causes damage to your kidneys.   When kidney damage occurs, you are unable to rid your body of excess urine, and wastes. Your blood electrolytes (such as potassium, and magnesium) will all become elevated. These conditions can often cause pain.

First, make full use of ASK.COM (put "spider biology" in ASK.COM'S search engine). And here's a Webster's "nephron" definition:\n\nEtymology: German, from Greek nephros\n: a single excretory unit of the vertebrate kidney\n\nThis means that if an arachnid has a nephron, it has a kidney.\n\nYou should be overwhelmed with ASK.COM'S information data base.\n\nGood luck!\n\nOTBPOC

The excretory system is responsible for removing waste materials from the body. The primary organ for excretion is the kidney which releases waste in the form of urine. Another organ of excretion is the skin which removes waste from the body in the form of sweat. Another organ of excretion is the lung. The lung is responsible for removing Carbon dioxide and water vapor. And the last member of the said system is the large intestine. The large intestine is responsible for removing undigested food from the body. The process of doing so is called elimination rather than excretion.

Most of the sugar and protein constituents that pass through the glomerulus are absorbed back into the circulatory system.  Check out the following diagram on illustration of how the nephron works:\n\nhttp://www1.shore.net/~straub/labsk_nephron.gif

the large molecules of sugar act as osmolar bodies, causing the kidneys to produce more urine by pulling fluid from the circulation.

The Kidney's primary function is to remove waste material from the blood stream.  Oxygen is used by every cell in the body to help metabolize nutrients.
