HOST DEFENSES Innate, nonspecific Acquired, specific See chapter 15 First line Second line Third line of defense of defense of defense Physical Chemial B and T lymphocytes, antibodies, cytotoxicity Genetic Inflammatory Interferons | Phagocytosis Complement barrlers barrlers barrlers response The first line of defense is a surface protection composed of anatomical and physiological barrlers that keep microbes from penetrating sterile body compartments. The second line of defense is a cellular and chemical system that comes Immediately Into play if Infectious agents make It past the surface defenses. Examples Include phagocytes that destroy forelgn matter, and Inflammation which holds Infections In check. The third line of defense Includes specific host defenses that must be developed uniquely for each microbe through the action of specialized whlte blood cells. This form of Immunity is marked by Its activity toward specific pathogens and development of memory. -art cummarivinm tha -

Evolutionary lineages

An evolutionary lineage is a series of populations of organisms that descend from a common ancestor. Each species in the lineage is the direct consequence of evolutionary change from a common ancestor. A phylogenetic tree is generally used to display lineages visually. Lineages are components of the phylogenetic tree of life. Molecular systematics procedures are widely used to predict lineages.
