Question

Obstacle to large scale transplantation of organs
is
(a) insufficiency of organ donors
(b) immunological rejection of foreign bodies
(c) religious or ethnic considerations
(d) lack of effective surgical techniques

Answer 1

Answer:

b)immunological rejection of foreign bodies

Explanation:

Organ transplantation is a medical procedure in which an organ is removed from one body and placed in the body of a recipient, to replace a damaged or missing organ. The major problem in organ transplantation is transplant rejection, during which the body has an immune response to the transplanted organ(non-self), possibly leading to transplant failure and the need to immediately remove the organ from the recipient.

So, the correct answer is 'Immunological rejection of foreign bodies'.

Answer 2

Answer:

(b) immunological rejection of foreign bodies

Explanation:

The principle obstacle standing in the way of large-scale successful transplantation of organs is the immunological reactions of foreign bodies. ... By weakening the immune system, immunosuppressant drugs decrease the body's reaction to the foreign organ.
