Answer 2

• Red blood cells from an O+ donor can be transfused into patients with A+, B+, AB+, and, of course, O+ blood types.
• Persons with type O- blood are known as universal donors because their donated red blood cells have no antigens for A, B, or Rh, making them safe to give to people of any blood group.
• Because they have no antibodies to A, B, or Rh in their blood, people with type AB+ blood can get red blood cells from any blood type donor.
