Yes it is...

I only know the first part, but... (Click to Show Hidden Text)

Opsonins are a broad category of molecules that can mark a cell for phagocytosis.

I guess I'll just ask a question to get the marathon up and running again...
Which of the leukocytes primarily target parasites, and how do they (leukocytes) destroy them (parasites)?

Sorry for post spamming, but I literally just remembered that (Click to Show Hidden Text)

Eosinophilic Granulocytes attack their targets with cytotoxic granule proteins

It's so weird how the moment I start to think of something else, the answer to this question just floats out of the dark corners of my mind.

YES!!!
Very good! You got exactly what I wanted.
Your turn!

Yay

Explain the dangers of a mother being Rh- and her fetus being Rh+ and explain why usually only the second child is at risk.

Ha, Heredity! (Click to Show Hidden Text)

When the mother is Rh- & the child is Rh+, the Rh antigens produced by the mother may cross the placenta. When the second fetus is also Rh+, the antigens are already formed, so they are much more likely to attack the fetus (risk increases with successive children).

Exactly!
Also would've liked a mention of how the blood of the fetus and the mother have a much higher chance of mixing during delivery than during the pregnancy, so after the first birth the danger would skyrocket.

Oh, that's something I didn't know about that. I'll have to add that to reference
