Biology, nursing: what is blood serum, vs blood plasma?

Tutoring biology, you might be asked about blood serum and/or blood plasma. The tutor mentions a distinction.

In yesterday’s post I give an explanation of blood plasma: it’s blood minus the red blood cells, white blood cells, and platelets. Some people might see it as the liquid that carries the blood cells and platelets.

Blood serum is related, but has a specific difference from plasma:

blood serum:

plasma after fibrinogen has been removed from it.

Fibrinogen is a protein that weaves the physical blood clot.
