during the clotting processes
Globulins Antibodies-helps protect the body from pathogens
Transport protein
Plasma: Substances transported by blood -Nutrients (glucose, fatty acids, amino acids, vitamins)
-Waste products of metabolism (urea, uric acid)
-Respiratory gases (O2 and CO2)
-Hormones (Steroids and thyroid Hormone are carried by plasma proteins
Serum Fluid component of blood without the clotting factors)
-Salts
-Non-clotting plasma proteins (albumin and globulins)
-Nutrients (e.g., glucose)

-Hormones
Formed Elements -Erythrocytes (RBC's)
-Leukocytes (WBC's
-Platelets
Origin of Formed Elements -Originate from a multipotent hematopoietic stem cell known as a hemocytoblast
-Can produce Myeloid Stem Cells OR Lymphoid Stem Cells
Myeloid Stem Cells Leads to the formation of platelets, erythrocytes, and granulocyte immune cells
(Basophils, Neutrophils, Eosinophils)
Lymphoid Stem Cells Leads to the formation of agranulocyte immune cells
-Natural killer cells and T-cells and B-cells
-Lymphocytes
-Monocytes
Granular -Granules in cytoplasm can be stained
-Lobed nuclei
