So in a nutshell.
Blood is composed of plasma
which is mostly water and blood cells.
These blood cells include red blood
cells, white blood cells and platelets.
Red blood cells are generated in the bone marrow
after stimulation by erythropoeitin from the kidneys.
Hemoglobin is the iron-containing
oxygen transport protein of red blood cells.
There are different types of white blood cells including
granulocytes which are basophils, eosinophils and neutrophils.
Lymphocytes which are natural
killer cells are B-cells and our T-cells,
and monocytes which are eventually
going to mature into macrophages.
Platelets are responsible for
maintaining the hemostasis of the body,
and you need to be aware when
you're drawing from a pediatric patient
the safe volume and the site
basedoin the child's age and weight.
