Understanding Blood Types and Rh Factor

The video explains the different blood types based on sugar antigens: A, B, AB, and O. It further discusses the Rh factor, a protein antigen that determines whether a blood type is positive or negative. The presence of Rh factor makes a blood type positive, while its absence makes it negative. The video also covers blood donation compatibility, highlighting that individuals with negative blood types can develop antibodies against the Rh factor, affecting donation compatibility.

Which antigens are responsible for determining the basic blood types?

• Nucleic acid antigens

• Lipid antigens

• Sugar antigens

• Protein antigens

What is the Rh factor in blood types?

• A protein antigen

• A type of sugar antigen

• A nucleic acid antigen

• A lipid antigen

What distinguishes a positive blood type from a negative one?

• Presence of sugar antigens

• Presence of Rh factor

• Presence of lipid antigens

• Presence of nucleic acid antigens

Why can't an AB+ individual donate red blood cells to an AB- individual?

• AB- individuals have a different protein antigen

• AB+ individuals have different sugar antigens

• AB- individuals can develop antibodies against Rh factor

• AB- individuals lack sugar antigens

Who can an AB- individual donate red blood cells to?

• Only AB+ individuals

• Only AB- individuals

• Both AB+ and AB- individuals

• Neither AB+ nor AB- individuals
