As blood is sent through the capillaries, some of it is filtered through the epithelial wall into the interstitial spaces around the cells in tissues.  This fluid is slowly forced into small little vessels called lymph vessels.  Lymph is the best way of finding out if there are bacteria, virus (pathogens) or even allergens/antigens in the tissues.  The lymph eventually drains into lymph nodes which are major sites for immune system communication. As fluid enters, some is pushed out.  These lymph vessels continue to merge until they become a major lymph vessel that drains in the subclavian vein.  This merges with the vena cava and thus returned to blood circulation.

blood, fluid pumped by the heart that circulates throughout the body via the arteries, veins, and capillaries (see circulatory system; heart). An adult male of average size normally has about 6 quarts (5.6 liters) of blood. The blood carries oxygen and nutrients to the body tissues and removes carbon dioxide and other wastes. The colorless fluid of the blood, or plasma, carries the red and white blood cells, platelets, waste products, and various other cells and substances

Blood's role in the body is three fold: First, it acts as a transort system for nurtients and such to reach the different parts of the body. Secondly as a defence system, where lymphocytes are active in controlling pathogens that enter the body (such as bacteria, viruses, fungi, etc). Lastly, the blood acts as a sealant. When there is damage to the body, the platelets in the blood seal up the wound.\n\nBlood is very important to the body. Without it, you wouldn't exist.

The heart is a powerful muscle slightly larger than your clenched fist. It works as a pump to send oxygen-rich blood through all parts of your body. Blood contains oxygen and nutrients that every cell in your body needs to survive. The oxygen-rich blood travels throughout the arteries and vessels, nourishing the body so that it can function properly.\n\nYour heart will beat an average of 100,000 times per day. In that time, it pumps more than 4,300 gallons of blood throughout your entire body.

"Arteries are muscular vessels that carry blood away from the heart to the tissues and organs of the body (The vessels which return blood to the heart are veins)."\n\n"Capillaries are the smallest of a body's blood vessels, measuring 5-10 μm. They connect arteries and veins, and most closely interact with tissues."

Ill try-\nBlood comes into the right atrium, then to the right ventricle..it stays on the right side at first.  This blood doesnt have any oxygen in it, so the first thing you have to do is get it oxygenated-So, the blood goes from the right ventricle to the lungs.  Here, the blood picks up oxygen for the rest of the body, but it still has to be pumped to the rest of the body.  So the blood goes fro mthe lungs back to the heart, but this time it goes into the left atrium, then the left ventricle-from there is goes everwhere in the body, delivering oxygen.  Now, once the body has taken all the oxygen out, the blood goes back to the right atrium, for the whole cycle to start again.\nhere's the overall flow:\n\nBlood from the body without oxygen--->\nright Atrium--->Right Ventricle--->\nLungs, so it can get oxygen--->\nLeft Atrium--->Left Ventricle--->\nRest of the body, to deliver oxygen---->\nBack to the right atrium once the oxygen is used.

Basically by osmosis. The cell absorbs nutrients and oxygen through the cell wall from the blood circulating in the capillaries. The oxygen is absorbed by the body in an exchange in the lungs and nutrients are absorbed through the small and large intestine and they all travel in the blood stream to the cells.

The Cardiovascular System\n\n\n The cardiovascular system and the lymphatic system form what is collectively called the circulatory system. Together, these systems transport oxygen, nutrients, cell wastes, hormones, and many other substances to and from all cells in the body. The trillions of cells in the human body take up nutrients and excrete wastes every minute of every day. Although the pace of this exchange may increase with activity or slow with rest, it happens continuously. If it stops, so does life. Of the two systems, the cardiovascular system is the primary transport operator; the lymphatic system aids it in its function.\n\n\nDesign: Parts of the Cardiovascular System\n\nCardiovascular comes from the Greek word cardia, meaning "heart," and the Latin vasculum, meaning "small vessel." The basic components of the cardiovascular system are the heart, the blood vessels, and the blood. The system can be compared to a large muscular pump (the heart) that sends a fluid (blood) through a series of large and small tubes (blood vessels). As blood circulates through the increasingly intricate system of vessels, it picks up oxygen from the lungs, nutrients from the small intestine, and .....

The circulatory system is made up of the heart, blood, and blood vessels. It is called the 'transportation system' of your body because it transports nutrients, oxygen, and cellular wastes to the proper places throughout the body.

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...

There are a number of different cell types in circulation in the blood stream. Here's a quick review:\n\nRed cells carry oxygen to the cells of the body. They are essentially bags of hemoglobin, the oxygen carrying molecule. Hemoglobin binds oxygen to iron atoms, which give the hemoglobin and thus the cells their distinctive red color. \nWhite cells (leukocytes, "clear cells") are divided into two types: \nPolymorphonuclear cells, are of three types: neutrophils, eosinophils, and basophils. \nNeutrophils fight bacterial infection. They form pus and are the chief ingredient of an abscess. See band cells. \nEosinophils are cells which are strongly related to allergy and the recognition of foreign things in the body such as parasites. \nBasophils are cells that are also part of the allergy and parasite recognition system.\nLymphocytes are the virus killers. There are two types of these: \nT-cells which remember what germs we've been exposed to and how to kill them. T-cells are the key component of the immune system that is missing in AIDS. \nB-cells that secrete the actual antibodies that attach to viruses and bacteria and identify them as things to be destroyed - rather like tagging the target with a laser so that the smart bomb will home in and blast the target. \nMonocytes are cells that are related to lymphocytes but have a killing and cleaning function. They cruise through the tissues of the body cleaning up debris and killing any bacteria they find. They are often increased in viral infections - a reassuring finding that your doctor may note on your child's blood count. See mononucleosis. \nPlatelets are the cells that plug leaks in the vascular system, the clotting cells. \n\n What are the different blood groups?   \n   The differences in human blood are due to the presence or absence of certain protein molecules called antigens and antibodies. The antigens are located on the surface of the red blood cells and the antibodies are in the blood plasma. Individuals have different types and combinations of these molecules. The blood group you belong to depends on what you have inherited from your parents.\n\nThere are more than 20 genetically determined blood group systems known today, but the AB0 and Rh systems are the most important ones used for blood transfusions. Not all blood groups are compatible with each other. Mixing incompatible blood groups leads to blood clumping or agglutination, which is dangerous for individuals.\n\nNobel Laureate Karl Landsteiner was involved in the discovery of both the AB0 and Rh blood groups.\n\n \n\n \n   \n    AB0 blood grouping system   \n    According to the AB0 blood typing system there are four different kinds of blood types: A, B, AB or 0 (null).\n\n \n   \n   Blood group A\nIf you belong to the blood group A, you have A antigens on the surface of your red blood cells and B antibodies in your blood plasma.\n\n\n\n \n   \n   Blood group B\nIf you belong to the blood group B, you have B antigens on the surface of your red blood cells and A antibodies in your blood plasma.\n\n\n\n \n   \n   Blood group AB\nIf you belong to the blood group AB, you have both A and B antigens on the surface of your red blood cells and no A or B antibodies at all in your blood plasma.\n\n\n\n \n   \n   Blood group 0\nIf you belong to the blood group 0 (null), you have neither A or B antigens on the surface of your red blood cells but you have both A and B antibodies in your blood plasma.\n\n \n\n \n   \n    Rh factor blood grouping system   \n \n \n   Many people also have a so called Rh factor on the red blood cell's surface. This is also an antigen and those who have it are called Rh+. Those who haven't are called Rh-. A person with Rh- blood does not have Rh antibodies naturally in the blood plasma (as one can have A or B antibodies, for instance). But a person with Rh- blood can develop Rh antibodies in the blood plasma if he or she receives blood from a person with Rh+ bloo

Red blood cell: The blood cell that carries oxygen. Red cells contain hemoglobin and it is the hemoglobin which permits them to transport oxygen (and carbon dioxide). Hemoglobin, aside from being a transport molecule, is a pigment. It gives the cell its red color (and name). \nThe mature red blood cell (RBC) is a non-nucleated biconcave disk. Thanks to this unusual shape and its hemoglobin content, the RBC is superbly suited to the transport of oxygen. \nA red blood cell is sometimes simply referred to as a red cell. It is also called an erythrocyte or, rarely today, a red blood corpuscle.\n\nWhite blood cell: One of the cells the body makes to help fight infections. There are several types of white blood cells (leukocytes). The two most common types are the lymphocytes and neutrophils (also called polymorphonuclear leukocytes, PMNs, or "polys"). \n\nLymphocytes are made in lymphoid tissue in the spleen, lymph nodes, and thymus gland. There are different kinds of lymphocytes. Lymphocytes identify foreign substances from germs (bacteria or viruses) in the body and produce antibodies and cells that specifically target them. It takes from several days to weeks for lymphocytes to recognize and attack a new foreign substance. \n\nNeutrophils are also major players in the body's defense against bacterial infections. Neutrophils are made in the bone marrow and circulate in the bloodstream. Neutrophils move out of the blood vessels into the infected tissue to attack the bacteria. The pus in a boil (an abscess) is made up largely of neutrophils. Normally a serious bacterial infection causes the body to produce an increased number of neutrophils, resulting in a higher than normal white blood cell count (WBC). When the WBC is low, there may not be enough neutrophils to defend against bacterial infections. \n\nThe white blood cell count is done by counting the number of white blood cells in a sample of blood. A normal WBC is in the range of 4,000 to 11,000 cells per microliter. A low WBC is called leukopenia. A high WBC is termed leukocytosis. \n\nA normal absolute neutrophil count (ANC) is in the range of 1,500 to 8,000 cells per microliter. If the ANC is below 500 for an extended period of time, the risk of serious bacterial infection may increase significantly. A low neutrophil count is called neutropenia.

Your heart is a pump that circulates blood through the many veins and arteries in your body...oxygenated blood leaves your heart ,in your arteries, flows to your tissues, organs and cells depositing oxygen then returns through your veins back through your lungs to heart to re oxygenate the the cycle starts over.

The lungs (respiratory system) take in air (using the oxygen and breathing out the carbon dioxide), the heart pumps the oxygen through our arteries (circulatory system)making our blood red.

The average blood cell makes a round trip through the body's arteries and veins every 60 seconds, and can hit speeds of up to 10 mph. The heart pumps your five quarts of blood around your body 500 times a day.
