If type O blood is transfused into a person with blood type B what will need to be done to the blood?
Since a patient with Type B blood has B antigens on their RBC's and since Type O blood has both anti-A and anti-B antibodies present in the blood plasma, the donor blood needs to be treated before transfusion. The Type O blood needs to be separated into packed cells and plasma, usually done by centrifuge, and only the packed cells should be used for the transfusion. Remember the anti-B antibodies are present in the Type O blood plasma and could cause serious damage in the system of a patient with Type B blood.
Is the plasma membrane of cells prokaryotic or eukaryotic?
The plasma membrane of cells is found in both prokaryotic and eukaryotic cells.
What do plasma cells form from?
Plasma cells form from B cells that have been specifically activated by antigens. Upon activation, B cells differentiate into plasma cells which are responsible for producing and secreting antibodies to fight off pathogens.
What is the four components of blood?
The four components of blood are red blood cells, white blood cells, platelets, and plasma. Red blood cells carry oxygen to the body's tissues, white blood cells help fight infections, platelets aid in blood clotting, and plasma is the liquid portion of blood that carries nutrients and hormones.
Are plasma cells and helper t cells the same thing?
No, plasma cells and helper T cells are different types of immune cells. Plasma cells are a type of B cell that produces antibodies, while helper T cells are a type of T cell that helps activate other immune cells, including B cells.
How packed red cells preparation?
Packed red cells are prepared by removing most of the plasma from whole blood through a process called centrifugation. This centrifugation process separates the red blood cells from the plasma and other cellular components, resulting in a concentrated suspension of red blood cells. The packed red cells are then typically suspended in a small amount of saline solution before being transfused to a patient.
What is the fluid above the packed cells?
These is called the Plasma.
What is packed rbc?
Packed red blood cells (PRBCs), also called "packed cells," are a preparation of red blood cells that are transfused to correct low blood levels. A unit of PRBCs begins as a 450 milliliter volume of whole blood. Platelets and plasma are removed to leave a preparation of 220 milliliters of mostly red blood cells. This step concentrates the red blood cells so that they occupy less space, thus the term "packed." One unit of PRBCs typically will raise the hematocrit by 3-4% and the blood hemoglobin concentration by 1 gm/dl. PRBCs last in refrigeration for up to 42 days, but under the right conditions, they can be frozen for up to a decade.
Why is fresh frozen plasma yellow and not red?
You do not have red blood cells in the plasma. Plasma means blood minus red blood cells. So you see the original yellowish colour in case of the blood plasma.
Which part of blood has the longest life span?
Lymphocytes. They need to stick around as memory to fight reoccuring infections.
Whole blood is packed with what?
Whole blood is made up of 3 parts - red blood cells, plasma and a Buffy coat which contains white blood cells and platelets.
What is the purpose of washing red blood cells?
The purpose of washing red blood cells is to remove unwanted substances such as plasma, preservatives, or residual components from the blood donation process. This helps prevent adverse reactions in the recipient and ensures that only the red blood cells are transfused.
Plasma cells develop from transformed b cells or t cells?
ativated B cells forms effector cells which are called plasma cells
How much do you get for donateing blood?
Blood from paid donors cannot be used in the United States for transfusion purposes. This is an FDA regulation, studies show that volunteer donors provide a safer blood supply. Plasma is the only component for which donors are sometimes paid, and it is taken by the apheresis method. Plasma can be treated for safety in ways that blood cells cannot. Plasma taken from paid donors is generally treated and processed by pharmaceutical companies into drugs. It cannot be transfused in the form of cryoprecipitate or fresh frozen plasma. Often however, donation sites give out small rewards like a shirt or coupons.
If type O blood is transfused into a person with blood type B what will need to be done to the blood?

Antibodies are produced by what?
Plasma Cells, lymphocytes .
Which cell develops into a plasma cell?
Stem cells develop into plasma cells and B cells also turn into plasma cells. Plasma cells have been exposed to an antigen and then produces and secretes antibodies.
