Goal of 1st line of defense: to prevent pathogen from entering body

There are physical and chemical barriers where all exposed body entrances would be. Ex. Skin, mouth, eyes, nostrils.

-The skin: composed of tough dead cells that are constantly shedding- physical barrier bc it prevents pathogen from latching on. Skin also contains sweat and oil glands that secrete acids and oils that prevent the growth of pathogens- chemical barrier. Also, sweat contains lysozyme.

Saliva and tears: protect the mouth and the eyes from pathogen invasion. Saliva and tears contain lysozyme.

Nostrils, digestive + respiratory tracts lined with another barrier: mucous.

<h3 /><h3>Forensic anthropology</h3>

Forensic anthropology is an area of physical anthropology that seeks to establish the identity  of a human being through his skeletal remains, providing parameters of the biological profile  of individuals, assisting in the tasks of reconstituting identities within forensic science, for  humanitarian and legal reasons, aiming at estimate, establish or determine the species whether  

  • Human or animal
  • Age
  • Ethnicity
  • Stature
  • and Ancestry,

through a systematized technical

process.

<h3>Human identity</h3>

In human identity, there are two aspects:

  • the subjective  (personal identity)
  • and the objective (physical identity).  

Subjectively, each man has the impression of what he is

today what was yesterday and in the days before. Objectively,  can be demonstrated even if it is absent or disturbed  the impression of subjective identity that a certain body  human, living or dead, examined at the moment, is the  same as in the previous season, was subjected to the same  exam. The concept of identity encompasses two elements:  

  • uniqueness
  • and immutability,

but both have  biological foundation.

<u>There are several techniques in </u><u>forensic</u><u> science  to </u><u>determine the identity and age</u><u>, but the relationship of the individual's characteristics must always be interpreted correctly.</u>
