name the main organs responsible for excretion and what they excrete?
407914
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.

Liver:The liver is the largest internal organ in the human body\nFunction:It plays a major role in metabolism and has a number of functions in the body including glycogen storage, plasma protein synthesis, and drug detoxification.\nIt also produces bile,\nGall bladder:A part of Digestive system\n\nSpleen:Lymphatic system\nFunction:The spleen is a ductless, vertebrate gland that is not necessary for life but is closely associated with the circulatory system, where it functions in the destruction of old red blood cells.\n\nPancreas:A part of Digestive system and Endocrine system.\n\nPericardium:The pericardium is a double-walled sac that contains the heart \n\nCardiac valve:circulatory system\n\npyloric valve:Digestive system\nAt the end of pyloric stomach is presnt a strong circular muscle band,called pyloric valve

Ammonia is a chemical compound, and Excretion is to actively transport a substance outside of an area. So Ammonia Excretion is to move Ammonia outside of the cell/organism.

1) diffusion of gases in excretory system\n2) their gills pump H20 over one side and splits it up so oxygen flows over teh other to extract 02\n3) C02 diffuses out of cells

frogs have a cloaca, a single reservoir for both urine and feces.  Fortunately in humans these are divided so we have one opening for urine and another for feces.

The urinary system entails the kidneys(2 normally), the bladder, 2 ureters(tubes from kidneys to bladder), and the urethra (tube from bladder to opening in the body).\n\nLook in any anatomy and physiology book or yahoo health.

kidneys filter out the things our body doesn't need and sends the waste out as urine while sending the "good things", vitamins etc. to the rest of the body.

Well, glands are technically organs. Glands differ from other organs in that their primary function is producing and secreting some hormone/substance

Digestive System Organs\n\nEsophagus- A simple conduit between the mouth & stomach.\nStomach- Where the enzymatic digestion of proteins initiated and foods are reducted to liquid form.\nLiver- It's major role is to provide bile salts to the small intestine, which are critical for digestion & absorption of fats.\nPancreas- Important roles as both and endocrine & exocrine organ- provides a potent mixture of digestive ezymes to the small intestine which are critical for digestion of fats, carbs and protein.\nSmall Intestine- Where the final stages of chemical enzymatic digestion occur & where almost all nutrients are absorbed.\nLarge Intestine- Major differences among species in extent & importance - in all animals water is absorbed, bacterial fermentation takes place and feces are formed. In carnivores, that's about the extent of it, but in herbivores; like the horse, the large intestine is huge and of critical importance for utilization of cellulose.\n\nEXCRETORY ORGANS\n\nLUNGS- Diffuses carbon dioxide from the blood, into the lung tissue, and then leaves the body everytime we exhale.\nLIVER- The largest internal organ in our bodies. Its numerous functions make it part of the circulatory, digestive, and excretory systems. Some proteins & other nitrogenous compounds are broken down in the liver by a process called deamination. The liver produces bile, which is temporarily stored in the gall bladder before being released into the small intestine where it helps break down lipid molecules. The liver removes & breaks down old red blood cells. It is also responsible for maintaining normal levels of glucose in the blood. The liver is ALSO responsible for removing potentially hazardous chemicals from the blood. It "detoxifies" the blood.\nSKIN- Sweat comes out of pores in your skin. Sweat is a mixture of 3 metabolic wastes: water, salts, & urea. So as you sweat, your body accomplishes 2 things: sweating has a cooling effect on the body, and metabolic wastes are excreted.\nKIDNEYS- they filter the blood. The kidneys help filter the blood.\n\nRESPIRATORY \n\nNose & Nasal Cavity- airway, moistens & warms air, filters air, resonating chamber for speech, houses smell receptors.\n\nPharynx (throat)- connects nasal cavity to oral cavity & larynx & esophagus. Is a common path for air and food.\n\nLarynx (voice box)- Provides an open airway. Routes food to the esophagus & air to trachea.\n\nTrachea (windpipe)- Descends from larynx & divides into the 2 primary bronchi. Is mobile; stretches, recoils, moves side to side. \n\nLungs- are the collective arrangement of the respiratory zone.

Lizards _do_ have an excretory system, just like all vertebrates. \nTheir kidneys produce uric acid as final product of nitrogen metabolism, and uric acid combines to form salts (urates) that appear as whitish crystallized matter. \nThe end of the excretory ducts of lizards open at a cloaca, that also includes the end openings of the reproductive system and the digestive system. The excretions of lizards are of 3 types: brown solid matter (feces from the digestive system), white chalky semi-solid matter (urates), and clear liquid (urine). Often the feces and the urates are discharged together, that's why you see the white spot. \n\nThe same happens in birds, btw.

There are two organ systems that work in conjunction with each other to provide tissues with oxygen and remove carbon dioxide.  Those are the respiratory and the circulatory system (the major organs of these systems being the lungs and the heart respectively).\n\nNutrients are provided by the combined actions of the digestive and circulatory system, and wastes are removed through the combined actions of the circulatory and excretory systems.
