Septic arthritis is a rather rare but important disease characterized by inflammation of a synovial membrane with purulent effusion into the joint capsule, usually due to bacterial infection. It typically affects monoarticular joints.
Scientists estimate the volume of blood in a human body to be approximately 7 percent of body weight. An average adult body with a weight of 150 to 180 pounds will contain approximately 4.7 to 5.5 liters (1.2 to 1.5 gallons) of blood. An average child with a body weight of 80 pounds will have approximately half the amount of blood as an adult. Blood carries out many critical functions in the body.
Healthy arteries carry oxygen through the body. The adult heart pumps approximately 2,000 gallons of blood each day through an amazing, 60,000-mile-long network of arteries, veins and capillaries. Arteries are the blood vessels that carry oxygenated blood away from the heart to every organ in the body. In healthy individuals, arteries are clear, and blood can flow smoothly, but occasionally over time, they may develop a buildup of fatty deposits or plaque, commonly known as hardened or clogged arteries.
