Correct Answer - Option 1 : Lack of antibodies

The correct answer is Lack of antibodies.

  • A person with blood group AB is sometimes called a universal recipient because of Lack of antibodies.
    • People with type AB+ blood are universal recipients because they have no antibodies to A, B or Rh in their blood and can receive red blood cells from a donor of any blood type.
    • Plasma transfusions are matched to avoid A and B antibodies in the transfused plasma that will attack the recipient's red blood cells.
  • We lose consciousness if blood flow to the brain is cut off ,for more than 5 sec.
    • Fainting is the sudden and temporary loss of consciousness.
    • consciousness arises from neural activity in the cerebral cortex.
    • Anything that disrupts neural activity in the cerebral cortex can cause loss of consciousness.
    • The most common cause of fainting is insufficient blood flow to the brain.
