Question

A person injured in a road accident, with blood group ‘O’ can be given blood with, which of the following blood group:
(a) from ‘A’ and ‘O’
(b) from ‘B’ and ‘O’
(c) from ‘AB’ and ‘O’
(d) only from ‘O’

Answer 1

Answer:

only from O because O is universal donor

Answer 2

Answer:

(d) only from ‘O’

Explanation:

A person of blood group 'O' can receive blood only from that person who has blood group 'O'. Blood group 'O' is known as Universal donor and group 'AB' is known as the Universal recipient. 'O' has both the antibodies (anti-A and anti-B) while the blood of the AB group has no antibody on the surface of RBCs. So, a person with blood group 'O' can donate to the person having any blood group but can receive only from blood group 'O'.
