BLOOD a few facts


BLOOD a few facts
 - There are four types of transfusable products that can be derived from blood: red cells, platelets, plasma and cryoprecipitate.

- Typically, two or three of these are produced from a pint of donated whole blood – hence each donation can help save up to three lives.

- Donors can give either whole blood or specific blood components only. The process of donating specific blood components – red cells, plasma or platelets – is called apheresis.

- One transfusion dose of platelets can be obtained through one apheresis donation of platelets or by combining the platelets derived from five whole blood donations.

- Most donated red blood cells must be used within 42 days of collection.

- Donated platelets must be used within five days of collection – new donations are constantly needed.

- Plasma and cryoprecipitate are stored in frozen state and can be used for up to one year after collection.

- Healthy bone marrow makes a constant supply of red cells, plasma and platelets. The body will replenish the elements given during a blood donation – some in a matter of hours and others in a matter of weeks.

  2. Do you think Blood should be viewed as an organ?
    I found this thread interesting  http://answers.google.com/answers/threadview/id/564993.html
    _Blood's multiple functions make it also difficult to define as
    something MORE than an organ: an organ system.  Generally speaking, an
    organ system is something that is defined as such because we perceive
    it to have an overall functional similarity between its parts.  There
    are problems with this, of course.  The nervous system and the
    endocrine system both have multiple functions, and in fact they
    overlap on almost all of their functions.  Their structures are
    likewise similar, and most (if not all) neurotransmitters are also
    hormones (and vice versa).  It might make sense to define these as one
    organ system: the neuroendocrine system, as some have suggested.  But
    current consensus is that they are more manageable when considered as
    separate systems._

    _Blood's functions overlap many organ systems.  Blood has immune
    functions, for example (T cells, B cells, globulins, and so on).  It
    has endocrine functions (in that it carries hormones from point A to
    point B).  It has functions that are unique to it, as in the transport
    of oxygen, carbon dioxide, and other nutrients and waste products._

    _It is probably best (as in most convenient) to consider blood an
    organ, rather than a tissue (it is too complicated) or an organ system
    (its functions are too diverse).  This categorization is the most
    common one amongst medical scientists.  Blood transfusions are,
    incidentally, considered organ transplants, and the same considerations
    are necessary when transplanting blood as other organs.  Skin is
    heavier than blood, and thus, regardless of what blood is, skin is the
    largest organ._

  3. I've always wanted to know, just how painful Bone Marrow donation can be.

  4. Yeah, but how to create true artificial blood, with all of its properties induced by the digestion system, immune system, etc., so we could live on no matter what issues happen with the rest of the body except head?
