Red Blood Cell Red blood cells are the most common type of blood cell and are the vertebrate body's principal means of delivering oxygen to body tissues via the blood. Red blood cells are also known as RBCs or erythrocytes (from Greek erythros for "red" and kytos for "hollow", nowadays translated as "cell"). A schistocyte is a red blood cell undergoing fragmentation, or a fragmented part of a red blood cell.
Blood Cell A blood cell is any cell of any type normally found in blood. In mammals, these fall into three general categories:
*red blood cells, whose main purpose is the transport of oxygen *white blood cells, which act as immune cells and fight infection *Platelets, which are actually fragments of the large bone marrow cells known as megakaryocytes and are important in blood clotting
White Blood Cell White blood cells (also called leukocytes or immune cells) are a component of blood. They help to defend the body against infectious disease and foreign materials as part of the immune system. There are normally between 4x10 and 11x10 white blood cells in a litre of healthy adult blood.
As well as in the blood, white cells are also found in large numbers in the lymphatic system, the spleen, and in other body tissues.
Umbilical Cord In placental mammals, the umbilical cord is a tube that connects a developing embryo or fetus to its placenta. It contains major arteries and veins (notably the umbilical arteries and umbilical vein) for the exchange of nutrient- and oxygen-rich blood between the embryo and placenta. When the animal is born, the umbilical cord is severed and leaves only a small scar (the umbilicus) behind.
White Blood Cells (Album) White Blood Cells is the third album by American rock band The White Stripes, released in 2001 (see 2001 in music).
Red Blood Cell Distribution Width The red blood cell distribution width, or RDW, is a measure of the variation of red blood cell volume that is reported as part of a standard complete blood count.
Holy Umbilical Cord The Holy Umbilical Cord is a first order Christian relic, of Christ. Christian teaching generally states that Christ was assumpted to heaven corporeally. Therefore the only parts of his body available for veneration are parts he had lost prior—hair, blood, fingernails, his prepuce and the umbilicus remaining from his birth.
Umbilical Cord Blood Bank Umbilical Cord Banks, both private and public, have developed since in the mid- to late 1990s in response to the success of umbilical cord blood transplants in treating diseases of the blood and immune systems, such as Fanconi's Anemia and Leukemia. Umbilical Cord Blood, hereafter called "UCB", once seen as waste to be discarded after a birth, is now viewed as a precious resource. Since the first successful UCB transplant was performed on a child with Fanconi’s anemia in 1988, more than 2000 patients have been treated with this procedure. UCB contains hematopoietic stem cells, progenitor cells that can form red blood cells, white blood cells and platelets and can be used to treat many diseases of the blood and immune systems.
Peripheral Blood Cell Peripheral blood cells are the cellular components of blood, consisting of red blood cells, white blood cells, and platelets, which are found within the circulating pool of blood and not sequestered within the lymphatic system, spleen, liver, or bone marrow.
