capillary blood, bright red in color and which is oxygenated blood.
Arterial blood
dark red in color, contains increased amount of carbon dioxide and which is non-oxygenated blood.

Sulfhemoglobin
excessive inhalation of gas from defective stoves and from automobiles which is cherry red color of blood.
Carboxyhemoglobin

liquid portion
the most abundant protein in the blood. It binds with many drugs.
Albumen
the important role in the immune mechanism of the body. The globins carry drugs as well as sex and thyroid hormones, lipids and iron.
Globulins
the yellowish fluids of the blood in which numerous blood corpuscles are suspended. A Straw – yellow liquid formed when blood to which an oxalate has been added to prevent clotting is allowed to stand.

Methods of collecting blood
Capillary blood sample
