Question

1. what happens to red blood cells that are agglutinated?

Explanation:

Agglutinated red blood cells clump together. This clumping can lead to them being trapped in small blood vessels, blocking blood flow. The body's immune system or other mechanisms may then break them down, and the debris can be removed by the spleen or liver. Also, agglutination can cause hemolysis (rupture of red blood cells) in some cases, releasing hemoglobin into the bloodstream.

Answer:

Agglutinated red blood cells clump together, which can block blood vessels, be broken down (with debris removed by the spleen/liver), and may undergo hemolysis (rupture) in some cases, releasing hemoglobin.
