The liver puts some compounds into the bile, which is dumped into the gut and excreted in the stool.\n\nThe lungs exhale things that can go into gas phase from the blood stream into the alveoli--like the sulfenic acid derivatives that make garlic and onions cause your breath to smell wretched.\n\nSkin does its excretion by putting material into your sweat.\n\nNote that the liver, the kidneys, the skin and even body fat also metabolically modify things (chemically alter them), which not only deactivates them (or in some cases, activates them) but also makes them more easily excreted by the liver or the kidney, which are the primary systems that get rid of such things.\n\nThat help?

It works with each heartbeat.  The gas moves with each heart beat. The area of the lung where the blood takes the gas is called the A/C membrane (Alveolar/Capillary) the membrane is so thin so the gas can diffuse into the blood.

The liver contains many enzymes which are used to detoxify chemicals and useless compounds that are in to human body.  The names are not important, but that they are known is good enough for you to understand.\nIf your blood is tested and excessive amounts of any of these enzymes are found it usually means that the liver is damaged or is producing more of these enzymes that normal.\nAlcohol, hydrocarbons, drugs (including Tylenol) and other compounds can do this.  There are also diseases, usually called Hepatitis (but there are others) that can damage the liver tissue and allow the enzymes to be released.

1.  removal of dead blood cells\n2. stores platelets\n3. produces blood cells during fetal life.\n \n(p.s.  the "liver" metabolizes carbs, lipids, protein, processes drugs and hormones, excretes bilirubin, synthesizes bile salt, stores glycogen, phagocytize red blood cells, and activates vitamin D, Rodney)

There are several different ones you can do- liver/gall bladder, kidney, blood, lymph, and colon are the ones that come to mind right away.

The kidneys . They discard electrolytes through a membrane that the body doesn't use such as uric acid and keep those that the body uses like water. Other filters in the body are lungs, skin, liver,  and spleen

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. \n\nThe various functions of the liver are carried out by the liver cells or hepatocytes.\n\nThe liver produces and excretes bile required for dissolving fats. Some of the bile drains directly into the duodenum, and some is stored in the gallbladder. \nThe liver performs several roles in carbohydrate metabolism: \nGluconeogenesis (the formation of glucose from certain amino acids, lactate or glycerol) \nGlycogenolysis (the formation of glucose from glycogen) (muscle tissues can also do this) \nGlycogenesis (the formation of glycogen from glucose) \nThe breakdown of insulin and other hormones \nThe liver is responsible for the mainstay of protein metabolism. \nThe liver also performs several roles in lipid metabolism: \nCholesterol synthesis \nThe production of triglycerides (fats). \nThe liver produces coagulation factors I (fibrinogen), II (prothrombin), V, VII, IX, X and XI, as well as protein C, protein S and antithrombin. \nThe liver breaks down hemoglobin, creating metabolites that are added to bile as pigment. \nThe liver breaks down toxic substances and most medicinal products in a process called drug metabolism. This sometimes results in toxication, when the metabolite is more toxic than its precursor. \nThe liver converts ammonia to urea. \nThe liver stores a multitude of substances, including glucose in the form of glycogen, vitamin B12, iron, and copper. \nIn the first trimester fetus, the liver is the main site of red blood cell production. By the 32nd week of gestation, the bone marrow has almost completely taken over that task. \nThe liver is responsible for immunological effects- the reticuloendothelial system of the liver contains many immunologically active cells, acting as a 'sieve' for antigens carried to it via the portal system. \n\nHope this helps you...\nYou can also check this link if you want to know more:\nhttp://janis7hepc.com/Your%20Liver%20Functions.htm

Oxygen (as O2) enters the lungs and diffuses through the thin layer of epithelial cells into the blood stream, where it binds one of four sites on hemoglobin.  The hemoglobin carries the oxygen to the heart, where it is then pumped out to the tissues of the body.  Tissues uptake oxgen as needed, and give CO2 in return to the blood stream.  The CO2 is then carried back to the lungs, where more oxygen is taken up.\n\nOxygen serves as an oxidizer, while fuels (such as sugar and fats) serve as reducers.  The oxygen acts in what are called "Oxidation/reduction" reactions (aka Redox--defined by a transfer of electrons) which release an excess of energy.  That energy is used to make ATP (adenosine triphosphate), which acts as the energy carrying molecule of choice by the body.  The systems used to make ATP are primarily glycolysis and the electron transport chain.

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.

The liver has more than one role in the digestive system. I guess you could say that the liver comes first since it is responsible for the production of bile, which then stored in the gall bladder and secreted into the small intestine. Bile serves to emulsify fats.\n\nThe small intestine digests AND absorbs. The walls of the small intestine secrete digestive juices which break down carbohydrates into simple sugars, proteins into amino acids, and fats into their constituent fatty acids and glycerol. It also works with pancreatic juice - intestinal juice consists of enterokinase, which converts inactive trypsinogen in the pancreatic juice to the active form, trypsin, which causes the hydrolysis of proteins.\n\nThese simpler substances are then absorbed by the intestinal walls into blood capillaries, or the lacteal for fatty acids. The blood capillaries converge to form a hepatic portal vein, carrying the nutrients to the liver, where further metabolism of substances can occur.

Simple answer:\n\nDigestive - you eat food.\n\nCirculatory - during digestion the nutrients are taken from the food and put into your blood. The circulatory system carries the nutrients throughout the body.\n\nRespiratory - you inhale and exhale. The lungs give oxygen to the blood stream, which carries O2 to the entire body, as all processes need O2. Blood streams brings CO2 back to lungs where you exhale.\n\nExcretory - you eliminate the waste product of the food you ate, which provided nutrients to your body.

Without the liver there is no life! Your liver produces many substances and maintains the balance of many nutrients. Our body makes many waste products which can be excreted only by the liver. \n\nThe liver plays a central role in the detoxification of drugs. Drugs are being taken up by the liver, degraded and excreted. The liver acts as a filter and prevents the passage of bacteria from the gut into the blood. The liver is also an important player in our defense mechanisms. \n\nSince the liver can be affected by many things other than alcohol, it is totally conceivable that you can have problems with your liver.  Heredity, drugs, viruses, stds, etc. can all damage the liver.\n\nThis little poem says it all and was written by Pablo Neruda:\n\nOde to the Liver\n\nThere, inside, you filter and apportion \nyou separate and divide, \nyou multiply and lubricate \nyou raise and gather \nthe threads and the grams of life... \nfrom you I hope for justice: \nI love life: Do not betray me! Work on! \nDo not arrest my song.

Our skin is the largest organ of our body. Skin serves several functions: it guards the underlying organs and muscles, it regulates our body temperature, it provides our sense of touch and it synthesizes vitamins D and B.\n\nThe skin includes parts like our hair and nails. In addition, there are several layers to skin, e.g., the epidermis and the dermis. Skin accounts for 15% of our body weight so you can see why it's called the largest organ in our body.\n\nThe above is basic information and you can already see how complex skin is. So there's lets to research and talk about when you're talking about skin.\n\nHope this helps.

Oxygen enters through the mouth and nose (nasopharynx) and moves down into the trachea and into the lungs. Oxygen and Carbon Dioxide are exchanged in the lungs at the Alveoli. Oxygen enters into the blood stream and Carbon Dioxide leaves the blood stream to be expelled by the exhalation of the lungs. The Oxygenated blood travels from the lungs to the heart, the heart then pumps the Oxygen rich blood into the arteries which take that blood away from the heart and circulate it through the rest of the body. Veins Then come back to the heart carrying oxygen-depleted blood where they are pumped through the heart to the lungs where they get more Oxygen and once again travel back to the heart to be pumped back to the rest of the body. That completes the circuit.
