URGENT Explain why people with incompatible blood types aren’t able to share blood. What would happen if they had a blood transfusion from an incompatible blood type

Explanation:

In a case of blood transfusion where blood types are not compatible, the red blood cells will clump together and form clots that block blood vessels, as a result, causing death.

More detailed info if needed:

It's mostly because of antibodies:

What is antibodies: Antibodies are specialised proteins that are produced in response to anything that your immune system might need to fight off, such as bacteria and viruses.

A type blood has anti-B antibody in the plasma

B type blood has anti-A antibody in the plasma

AB has neither A nor B antibody in the plasma

O has both A and B antibody in the plasma.

For example, if someone with Type O blood received blood from someone with Type B blood, the recipient’s immune system would identify the new blood cells as foreign and therefore destroy them.
