Products of donated blood? (1 Viewer)

[.ben]

In reference to teh following dp:

"Analyse information from secondary sources to identify the products extracted from donated blood and discuss the uses of these products"

Do we have to know about EVERY component of donated blood used in DETAIL? or can we do like 3 or 4 in detail and the rest just identifiy?

It's an "analyse" dot point. You need to know in fair detail. Obviously the blood has a lot of factors and components, but just know the main ones.

Know your blood cells, plasma (and maybe the difference between plasma and serum), platelets, soluble components such as O2, CO2, etc.

Is this good:

"While donated blood can be directly for blood transfusions among other things,

usually it is broken into its separate components. These individual components

include red blood cells, white blood cells, platelets, plasma, factor VIII.

Red blood cells are a vital component of blood as they deliver oxygen to the body

tissue and remove carbon dioxide wastes from the body. RBC transfusions can be used

to temporarily increase the oxygen carrying capacity in people involved in accidents

who have lost a large quanitity of blood or patients suffering from anaemia (as

sickle cells cannot transport enough oxygen).

White blood cells, also known as immunoglobins, are used to fight infection and flow

throughout blood. Thus injecting immunoglobins can help a patient temporarily boost

their immune system aiding in destroying any pathogenic material which enter the

body. Immunoglobin transfusions are most commonly used patients who have an immune

deficiency condition such as AIDS.

Factor VIII is a protein present in the blood of humans which helps the clotting and

coagulation of blood. This component of the blood is commonly transfused into the

blood of haemophilliacs who lack this protein and thus cannot clot blood. "

If you have listed components including red blood cells, white blood cells, platelets, plasma, factor VIII, then you are expected to DISCUSS the uses of ALL these products, not only ones you want to talk about. And to save yourself in case a huge question come up, you should talk about "uses" not just one use.

Oic, thanks.

Nice. But USES? all i know for uses of RBC is for chronic anemic ppl who don't have enough RBC to carry Oxygen and for those who had severe blood loss in accident or trauma. As for white blood cells, they're used for ppl who have low immunity? But what are serums used for?They are exactly the same as blood plasma but don't have fibrin, right? What bout the uses of Blood plasma then?

i know that RBC can be transfused, but i thought that WBC couldnt be, because of the chemicls on the membrane of the cell. when transfused the body will recognise the chemicals as being foreign and reject that part of the blood.
before transfusing they skim off the WBC part.

You can transfuse WBC. You probably transfuse these cells to immunocompromised individuals anyway, so they don't really have a functional immune system in the first place to "reject" these foreign cells.

Hopefully you get what I mean.
