transplant

Question 1

Xenograft

Answer 1

tissue transplant between different SPECIES

e.g. porcine valve for non-metallic heart valve repair

since the heart valve has poor vascular supply there is a limited immunological reaction

Question 2

Allograft

Answer 2

tissue transplant from one individual who is genetically different

renal, cardiac, lung transplant
not from identical genetic background but important to match blood types and HLA as well as give immunosupression

Question 3

Autograft

Answer 3

transplant in which the individual acts as both the donor and recipient

e.g. burn in one specific area so a part of their body that’s intact is removed and transplanted

the immune system will not reject

Question 4

homograft

Answer 4

synonym for allograft

Question 5

isograft

Answer 5

tissue transplant between genetically identical individuals e.g twins

same HLA typing so very little chance of rejection
