There are a total of eight common blood types, with four of them being major types. The different blood type groups are based on the presence or absence of antigens as well as the antibodies found in each individual’s serum. The four main types of blood are A, B, AB, and O. Type A has only the A antigen on red cells and the B antibody in the plasma. Type B has only the B antigen on red cells and the A antibody in the plasma. Type AB has both A and B antigens, but neither A or B antibodies in the plasma. Type O has neither A or B antigens on the red cells and both A and B antibodies. According to the Language of Medicine textbook, 41% of people have type A blood, 10% have type B, 4% have type AB, and 45% have type O. On a more specific level, …show more content…
There are red blood cell, platelet, and plasma transfusions. Red blood cell transfusions occur when a patient has anemia or an iron deficiency. When they receive this transfusion, it increases their hemoglobin and iron levels and improves the amount of oxygen within their body. Platelet transfusions occur when patients suffer from leukemia or other types of cancer. These patients tend to have a low number of platelets due to chemotherapy. This transfusion allows the patient to receive enough platelets to maintain their body and health. Plasma transfusions are generally for patients with liver failure, infections, and severe burns. This allows them to receive important proteins that are crucial to the patient’s overall health and body. It’s interesting to know about the different types of blood transfusions and see how each benefit the …show more content…
I think it’s important to understand the various blood types for transfusions and when donating blood. In regard to the transfusion of blood, there can be detrimental effects when transferring blood from a donor to a patient/recipient. Thus, understanding the blood types helps to differentiate between what type of blood is compatible or incompatible with another. Knowing what your specific blood type is also important in terms of learning about any health risks and implications of your blood type. For instance, a Harvard study indicated that people with AB blood had a 23% increased risk for heart disease compared to those who had type O blood. Another example refers to people with type A in which they had 20% greater chance of developing gastric cancer than those with type O and B. However, lifestyle factors, such as diet, weight, and smoking, have a greater impact on these health risks. Nethertheless, it would still be important to learn about your blood type and see how the characteristics and implications differ from other
○ ABO incompatibility. People with an O blood type have antibodies that can attack blood cells in type A or B blood. If a mother 's blood type is O and her baby 's blood type is A or B, her antibodies may destroy the baby 's red blood cells and cause hemolytic disease.

Blood types, agglutination, carbohydrates, antigens and antibodies are all used to classify blood in health situations. There are four different types of blood types; type A, type B, type AB, and type O blood. Each of these blood types have specific antigen markers used for identification purposes, except type O, which contains no antigens. They also include antibodies that attack foreign invaders, except type AB, which contains no antibodies. The monosaccharide of each blood cell contains N-acetylglucosamine, galactose, and fructose. Type A, type B, and type AB has additional monosaccharides that differentiates itself from other blood types. Blood types can be determined by using the slide test method or test tube method, in which medical practitioners add antiserums and look for agglutination.
Wallace Terry has collected a wide range of stories told by twenty black Vietnam veterans. The stories are varied based on each experience; from the horrific to the heart breaking and to the glorified image of Vietnam depicted by Hollywood. Wallace Terry does not insinuate his opinion into any of the stories so that the audience can feel as if they are having a conversation with the Vietnam Veteran himself. Terry introduces the purpose of the book by stating, “ Among the 20 men who portray their war and postwar experiences in this book. I sought a representative cross section of the black combat force.”(p. XV) Although the stories in this book were not told in any specific order, many themes became prominent throughout the novel such as religion, social, and health.
Blood doping could have opposite effect of those intended. A large infusion of red blood cells could increase blood thickness and cause a decrease in cardiac output and a reduction in oxygen content. Both would reduce aerobic capacity. The human heart was not designed to pump thickened blood throughout the body and, therefore, it could lead to a multitude of problems. The diseases that can be contracted from autologous blood transfusion are severe. Even more frightening is the list of diseases that can be contracted through homologous blood transfusion. It includes hepatitis, AIDS, malaria, and CMV. In addition, shock is a factor to be aware of.
Although blood transfusions had been used before the First World War, many were not successful due to lack of knowledge in this type of treatments. World War I pushed the development of blood transfusions, allowing them to be safer. Before the war in the 17th century, blood transfusions often occurred with the use of animal blood, a practice that did not achieve desired results. These transfusions often times came from sheep, and although they were sometimes successful, it was discovered that any large amounts of transfusions would cause death. Coming to the conclusion that animal blood transfusions did not save lives, scientists looked to humans for human to human transfusions. Many of these attempted transfusions were met with failure but in 1818, Dr. James Blundell accomplished the first successful human blood transfusion; four ounces of blood were transferred to the patient from her husband. From that moment on, doctors began to learn even more about blood transfusions and how to do them properly. By 1901, the four human blood groups were discovered by Karl Landsteiner; with less differences in the bloods transfused together, coagulation and clumping amounts decreased. This benefited many lives in that toxic reactions to the wrong types of blood did not occu...
In recent years there has been an increase awareness regarding the potential risk of blood transfusion leading to increase scrutiny of its use by health care providers. (6). Studies have shown that by 1990s, the transfusion for CS has decreased to 1.1-1.6 % (7, 8) in some centers but remained relatively high (5.2-6.8%) in others (9, 10).Review of the available literature shows that need for transfusion varies in various countries.

2. People should give blood because it is easy and though there might be a little pain involved it is worth it because it saves so many lives and you get great snacks.
So I’m terrified of needles, but they say that what doesn’t kill you makes you stronger, and I am certainly banking on that to be true every time I go to the Blood Center to donate blood, which is about every two months. I don’t like it, but it’s just such a good thing to do. I used to give whenever they would come around in those buses, but I stopped doing that after my first visit to the Blood Center. I discovered that you get much more individual attention when you go to the Blood Center at about seven o’clock on a Thursday night.
Platelets, which are also produced in the bone barrow, are checked on a Complete Blood Count with Differential. Platelets help stop bleeding from injury by creating clots. If your CBC blood test shows low platelet levels, you might be more susceptible to bleeding. High platelet levels could mean that you have an increased risk of internal clots.
VI. Some individuals requiring blood are surgical patients; burn victims; accident victims; anemics'; hemophiliacs; seriously ill babies; and persons suffering from leukemia, cancer, kidney disease and liver disease.
Whether it be helping others that need a blood transfusion, or a supplemental source of income, donating plasma is an extravagant process that takes more effort than the normal citizen realizes. Previously I have explained the entirety of the donation procedure, including the waiting room ordeal, the donating, and then the end stages of the process. This information was presented so that others curious about plasma donation can vicariously live the donation process, and get a feel for what really goes on in the Biolife Plasma Center.
Today, there are more advanced lab tests to help doctors classify ALL so they no longer have to rely on just the cell’s characteristics. These new lab tests aid in the grouping of ALL based on the type of lymphocyte the leukemia stems from (B cell or T cell) and how mature the cancer cells are (American Cancer Society, 2013)54.... ... middle of paper ... ...

I have given blood before and I am aware of the questionnaire and procedures used during the blood donation process.
...ver problems. It may also make the person more likely to get infections. Blood transfusions may help control some symptoms. But this could lead to having too much iron, as it stated before. Too much iron could damage the heart, liver, and endocrine system.
