Three platelets, giant platelet
Goat monocyte
Guinea pig lymphocyte
Cow lymphocyte with granules
Hawk thrombocyte Dog platelet clump
Dog lymphocyte
Chameleon monocyte
Dog monocyte
Squirrel monkey basophil
Rhesus monkey basophil
Rabbit basophil
Horse eosinophil
Cat eosinophil
Dog eosinophil
Mouse neutrophil
Gorilla neutrophil
Hamster neutrophil
Snake red blood cells have
nuclei
Red blood cells are ‘biconcave’
(indented on both sides) causing
the center of the cell to look clear
on a blood film (above)
Llamas, alpacas, and camels
have oval red blood cells
Dog red blood cells
Wright's stain is employed to stain blood smears. It
exploits acidic and basic interactions with the cells to
make cellular characteristics visible. The typical
components are Eosin Y, Methylene Blue, and Azure B.
Neutrophils are the cells
primarily responsible for killing
bacteria. They have cytoplasmic
granules that stain poorly.
Eosinophils combat parasites
and allergens, and contain
cytoplasmic granules that stain
vibrant pink/orange with Eosin.
Basophils regulate allergic
responses and release
anticoagulants. They contain
granules that stain deep purple.
White blood cells, or leukocytes, are the cells of the immune system and include five subtypes:
Lymphocytes combat viral
infections and produce antibodies.
Their nuclei are rounded. Some
cells contain granules. Guinea pig
lymphocytes have Kurloff bodies.
Monocytes are precursor cells to
macrophages, cells responsible
for killing fungi and recycling cell
materials. Their nuclei are horse-
shoe to amoeba-like in shape.
Platelets, or thrombocytes in
non-mammals, are the cell
fragments that form blood clots.
They are sticky and tend to form
clumps in a blood smear.
There are 3 main types of blood cells: red blood cells, white blood cells, and platelets.
In mammals, white blood cells have nuclei but red blood cells and platelets do not.
In non-mammals, all blood cells contain nuclei, and platelets are called thrombocytes. Red blood cells, or erythrocytes,
are cells filled with hemoglobin,
the compound responsible for
carrying oxygen in the body.
To examine blood cells, a drop of blood is smeared
onto a glass slide. The slide will be stained and
viewed under a microscope.
