In general, there are three stages leading from iron deficiency to anemia: 1  First, there is an insufficient supply of iron, which causes iron stores in the bone marrow to be depleted. This stage generally has no symptoms. 2  Second, iron deficiencies develop and begin to affect hemoglobin production.
Surfactant immune function is primarily attributed to two proteins: SP-A and SP-D. These proteins can bind to sugars on the surface of pathogens and thereby opsonize them for uptake by phagocytes. It also regulates inflammatory responses and interacts with the adaptive immune response.
Definition - What does Anionic Surfactant mean? Anionic Surfactant is a surface active substance that contains wash active and degreasing abilities on the surfaces of metals. It lowers the surface tension of water and thus removes the dirt from the surfaces of the metals. Anionic Surfactant is one of the classifications of surfactants. In anionic surfactant, the hydrophilic part consists of negatively charged group. Examples of Anionic Surfactants are the basic soaps.
