If you are into learning, the very first thing you need to learn is
where/how to get information.
I ran a simple search with http://www.alltheweb.com/ using keywords "pig
and found this (first "hit")
The pig heart is interesting to us because it is very similar to the human
heart in anatomy, size and function. Its excellent
availability in most areas of the world, along with the similarities to the
human heart, make porcine heart tissue ideal for
transplant into humans. Of course, untreated porcine tissue would be
rejected very quickly by the recipient's body, in the same
way that a human's donated organ would be rejected. To prevent this, porcine
heart valves are treated with glutaraldehyde to
reduce their immunogenicity.
(there's more but I'll let you do the reading).
Find a good search engine and be sure you know where/if you are getting good
The url above is one of the best in Canada.
(also make sure that it's the most current info on the subject you are
Hope this helps
