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)?

Eosinophils,
Phagocytosis
Looking forward to anatomy, protein, fossils, and optics (NYS trial) this year!

Eosinophils,
Phagocytosis
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.

Yay :D

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

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 :)
