Blood grouping is a test to determine blood group of a person. Before blood transfusion or if you plan to donate blood, the test is important. Blood A cannot mix with blood B or blood AB so blood group is important to be known.A dangerous immune response will occur if receive blood that is not compatible with own blood type. The human immune system will destroy the incompatible blood type.
It is easy to determine the blood group by determining the types of antigen on the surface of the red blood cell. The body will differentiate the own cells and foreign cell(potentially dangerous) with the aid of antigens.Blood group A has antigen A, blood group B has antigen B, blood group AB has both antigen A and antigen B, and the blood group O has no both antigens. If there is an antigen, there is an antibody. The human body(immune system)
There are eight possible types , A+, A-,B+, B-,AB+,AB,-O+,and O- .Blood type O negative has long been considered a universal donor as it can donate to all blood group, either +ve or -ve.
Blood typing is done prior to a blood transfusion or when classifying a person’s blood for donation. Blood grouping is a fast and secure way to ensure the patient receive the right blood during surgery. Otherwise, the incompatible blood will cause blood clumping or agglutination, which can be fatal.
Blood typing is especially important for pregnant women. If the mother is Rh- and the father is Rh+, the mother and child will have different blood types. In these cases, the mother needs to receive a drug called RhoGAM. This drug will keep her body from attacking the baby’s blood cells if their blood becomes mixed, which often happens during pregnancy.
According to KenHub, the blood consists of cells, cell fragment and an aqueous solution(plasma).45% of blood are red blood cells, white blood cell and platelets and the rest are plasma which consists of water, plasma protein and
There are different types of bloodstain patterns that give a sense of what happened at the scene. The idea is to get a sort of background story from the random blood distribution. The different types of blood can tell us the method an assailant used such as passive blood stains. These stains are made from the drops off a weapon due to gravity. For instance, if an attacker w...
In most hospital delivery rooms, the doctors will routinely clamp and sever the umbilical cord with in fifteen to thirty seconds of the mother giving birth. When clamping the cord, the doctors will clamp the cord in two places, one close to the infant and then again in the middle of the cord another clamp. By delaying the clamping, fetal blood in the placental transfusion can provide the infant with an additional thirty percent more blood volume and up to sixty percent more blood cells (McDonald, S., & Middleton, P., 2009). This reduces the risk of the hemorrhaging that could occur after birth. But with new ongoing studies, it is said that by delaying the clamping of the cor...
Platelets like the plasma and red blood cells are collected from whole blood by centrifuging. But the major way that platelets are collected is by apheresis where as the blood is being drawn it is centrifuged and the platelets are collected into bags and the rest of the blood is then transfused back to the donor. The process may take up to an hour but these donations can be performed at 2-4 week intervals because the red blood cells are returned to the donor.
Thrombocytopenia affects 6% to 10% of all pregnant women and, other than anemia, is the most common hematologic disorder in pregnancy (McCrae, 2010). Blood consists of three main ingredients: red blood cells, white blood cells, and platelets. Each plays an essential function to provide the human body with elements and protects the body against any exterior viruses and infections. Platelets are responsible for helping blood to clot. A deficiency or disorder of platelets leads to a disease called Thrombocytopenia.
○ 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.
A organ donation is where you take the healthy tissue from one person and transplant is to another person. The types of organs that can be donated are kidneys, heart, liver,pancreas, intestines, lungs, skin, bone marrow, and cornea. Your liver, kidneys, and bone marrow can be donated by a living donor. Your lung, heart, pancreas, intestines, and cornea come from a deceased organ donation. Database has listed al...
Blood, that red life fluid involved with the creation of life, it is quite common yet not everybody has enough. As a good citizen, it is your responsibility to give what others need for life. The Red Cross has regular donation times and travels around to schools, offices, and cities quite often. Giving blood may be scary for some, but in time this will pass. There are a few things you can do to make your first time giving blood easier on your mind and body.
There are four different types of blood; A, B, AB, and O. This is called the ABO blood typing system. All four different types of blood serve the same purpose of transporting nutrients and oxygen throughout the human body. But what makes them different? Blood typing is based on the presence or absence of A and B cell antigens which trigger antibodies. Each kind of blood has it’s own antibody or immunoglobulin, which are proteins produced by the immune system to help stop intruders from invading your body. Therefore,
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...
Postpartum hemorrhage is the leading cause of maternal mortality in the world, according to the World Health Organization. Postpartum hemorrhage (PPH) is generally defined as a blood loss of more than 500 mL after a vaginal birth, more than 1000 mL after a cesarean section, and a ten percent decrease in hematocrit levels from pre to post birth measurements (Ward & Hisley, 2011). An early hemorrhage occurs within 24 hours of birth, with the greatest risk in the first four hours. A late hemorrhage happens after 24 hours of birth but less than six weeks after birth. Uterine atony—failure for the uterine myometrium to contract—is the most common postpartum hemorrhage (Venes, Ed.).(2013). Other etiologies include lower genital tract lacerations, uterine inversion, retained products of conception and bleeding disorders (Kawamura, Kondoh, Hamanishi, Kawasaki, & Fujita, (2014).
Complete Blood Count with Differential is one of the most commonly ordered tests for routine check-ups and/or physicals. A complete blood count with differential measures the levels of red blood cells, white blood cells, platelet levels, hemoglobin and hematocrit. Most of the time it is ordered as a screening test to check for anemia or infection. The Complete Blood Count with Differential is used to aid in diagnosing and treating a large number of conditions (Lockwood, 2013).
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 will be investigating Human Blood as my specific tissue and giving an overview on the location, characteristics, and the benefits it has to the human body. Blood is extracellular matrix that is consists of plasma, red blood cells, platelets, and white blood cells. Blood is located within the capillaries/veins/arteries of the human body, which are blood vessels that run through the entire body. These blood vessels allow the blood to flow smoothly and quickly from the heart to distinct parts of the human body. The unique parts of human blood all work together for a purpose: the Red Blood Cells(erythrocytes) transports oxygen throughout the body, White Blood Cells(leukocytes) play a part in the bodies immune system, Platelets(thrombocytes) assist in creating scabs,
