1. Each red blood cell carries a protein called an and B). 2. Plasma carries 3. A transfusion reaction occurs when the antibodies of one blood type attack the cells of the other blood type, causing the cells to clump together; the process of producing large clumps of cells is called 4. During a reaction, red blood cells may burst; this is called 5. Blood type completely accurate. Reactions usually do not occur because only the of which there are two types (A against the of the other blood types. is sometimes called the universal donor, although the term is not are being transfused. is sometimes called the universal recipient, although this is not 6. Blood type completely accurate either. 7. Many people also carry another antigen, called the Rh antigen; when this is the case, they are said to have Rh- blood.

Imagine you are a surgeon. Five patients in the hospital are in urgent need of different organ transplants to survive. One of them needs a heart, one a lung, one a liver, and the other two each a kidney. All five happen to have the same rare blood type, so it is hard to find the right donor. At this time, a foreign traveler came to the hospital for a simple body check. By chance, he has the same rare blood type as theirs. With your expertise, as long as you use some simple medication to end the life of the traveler painlessly and without the notice of others, then his organs can save the five people awaiting organ transplants What would you do? Would you kill one person to save five people?

colony forming units reticulocyte hemopoiesis hematopoietic stem cells erythropoiesis hemopoiesis is the production of blood, especially its formed elements. Red bone marrow produces all seven formed elements. The process begins with specialized cells called hematopoietic stem cells , which have the ability to develop into all formed elements. When more of a particular formed element is needed, some of these specialized cells will transform into colony forming units that are fate-determined to become only the type of formed element that is currently needed. These will then multiply in number, maturing into a series of precursor cells before finally becoming the desired formed element. erythropoiesis is specific name for hemopoiesis when new erythrocytes are being made. It follows the pattern above, producing a series of precursor cells, which ultimately results in the nucleus being discarded, and an immature cell called a reticulocyte being produced. This cell is released into the…
