About how many RBCs, Platelets, and WBCs each are in a microliter of blood?
5-10 million RBCs
200-400 thousand platelets
4-12 thousand WBCs
200-400 thousand platelets
4-12 thousand WBCs
What is central pallor and where is it seen?
It is the pale center of RBCs due to membranes being really close together in dogs and humans.
What is rouleaux and where is it normally seen?
Rouleaux is stacking of cells like coins due to attractive electric charges. It is seen in horses and cats.

RBCs that look like targets because of a change in cholesterol phospholipid that changes the consistency of the membrane.
What are stomacytes?
Cells that have the inner lipid bilayer folded which results in a mouth-shaped structure.
What are dacryocytes?
Teardrop shaped RBCs caused by not returning to normal morphology after moving through capillary.
What is agglutination?
RBCs stuck together because of an anitgen-antibody reaction. It is not normal in any animal.
