Blood is made up of several different components. There are also 4 different blood types. You must research the different parts of blood and what each component does for the body as well as the different blood types. Once you have found this out you should make your ideas clear on why it is important to have stores of all of these components on hand in hospitals.
There are four different types of blood, O, A, B and AB. in the early 20th century, an Austrian scientist called Karl Landsteiner realized that blood is not only red and it gets pumped from the heart. He noticed that when he put different people's blood under a microscope, some distinct differences were visible. He won the Nobel Prize for his efforts. (quote) "Landsteiner observed two distinct chemical molecules present on the surface of the red blood cells. He labeled one molecule "A" and the other molecule "B." If the red blood cell had only "A" molecules on it, that blood was called type A. If the red blood cell had only "B" molecules on it, that blood was called type B. If the red blood cell had a mixture of both molecules, that blood was called type AB. If the red blood cell had neither molecule, that blood was called type O."

Part B~ It is obviously important to have spare blood at hand in hospitals, if a patient is losing critical amounts of blood, even if a simple incision is made, blood is still usefull to have at hand as a "back up" if the patients own blood stops circulation or some other problem with the production of blood. (quote)
ReplyDeleteA person with type A blood can donate blood to a person with type A or type AB. A person with type B blood can donate blood to a person with type B or type AB. A person with type AB blood can donate blood to a person with type AB only. A person with type O blood can donate to anyone.

There are 4 different components that make up your blood and each component benefits your body in some way. These components are: White blood cells, Rdd blood cells, Platelets and Plasma
ReplyDeleteWhite Blood Cells or leukocytes approximately make up 1 % of a fully grown adults blood. The white cells defend the body by fending off disease and foreign materials
Red Blood Cells or erythrocytes take up roughly around 40 to 50% percent of blood depending from person to person. Red blood cells are responsible for transporting oxygen to all of the bodies living tissues and carry away carbon dioxide
Platelets or thrombocytes in your blood work at blood-clotting in wounds. They also kill infections near the wounds by releasing proteins which kill bacteria and other harmful microbes.
Plasma takes up 55% of our blood volume. It is a contains water, sugar, salt ,fat and protein solution which brings nourishment to cells and flushes our waste of metabolism
There are also 8 different blood types. A+, A-, B+, B-, AB+, AB-, O+, and O-. According to the Australian Red Cross most Australians (40%) have the blood type O+ and the blood type AB- being the rarest among australians( 1%)
Type A and B both carry a different antibody and a different antigen
Type AB carries both antigens but no antibodies
Type O carries both antibodies but no antigens
It is vital for hospitals to store all 8 kinds of blood types as well as a lot of plasma for blood transfusions

ReplyDeleteI agree with everyone who has posted a comment that giving blood is something that most people can do and is important. The blood bank is always needing blood deposits to help people who are sick or have had an accident and need blood transfusions. It's easy to give blood because there are mobile vans that travel around suburbs, it only takes less then an hour and you only need to give a few times a year to make a big difference.
Think about this - your donation of blood could save a life and one day someone else's blood donation could save yours. What is more special than that?

ReplyDeleteI fully agree with what has been said in all the blogs. Adam (May 27, 2009 3:13 AM) has stated that, what can be better than knowing that you have saved someone’s life and that one day someone could save yours from one single blood donation. Everything that has been said above is so true, how good would that feel. Anyone can donate anywhere who has nothing wrong with their blood and is over the age of 18 otherwise with parental permission. All the blood that is donated will never go to waste and always is used to help save lives. Blood donations can be used for many things such as a rapid loss of the blood, after operations and basically anything that is wrong with the blood that needs more blood or healthier blood. Blood is a very important part of the body and should never be wasted.

ReplyDeleteI agree with Sunny.Li (May 20, 2009 3:21 AM) when he says that it is important to store plasmas and some of each type of blood (A+, A-, B+, B-, AB+, AB-, O+, and O-)at a hospital in case of the urgent need of blood transfusions. Each type of blood can be used in transfusions differently so without all of the different types blood it is impossible to give blood to everyone.‘A person with type A blood can donate blood to a person with type A or type AB. A person with type B blood can donate blood to a person with type B or type AB. A person with type AB blood can donate blood to a person with type AB only. A person with type O blood can donate to anyone.’ (quote from Tom May 20, 2009 2:06 AM). Plasma is the liquid portion of the blood — a protein-salt solution in which red and white blood cells and platelets are suspended.
Everybody that can give should because it’s a bit of a myth that anyone can do it. Lots of people can’t because they are very strict about who can give. Some people can’t give because they are pregnant, sick, on medication, have a disease, are old, recovering from illness or have travelled overseas to countries where serious disease like mad cow was going around at the time. That’s why it’s really important for everyone to volunteer.
