Keratin. Collagen is what makes the dermis tough.
These proteins are called antibody.
Mucus is found in the respiratory system of humans. The function of mucus is to protect the body from infectious agents such as viruses and bacteria.
When antibodies bind to the epitopes of an antigen(bacteria) via antigen receptors, the antibodies present the bacteria to a macrophages in a form that they recognize the foreign substance and engulf them. This antibody-antigen "team work" is also known as opsonization
Three biological warfare agents that are bacteria are: Anthrax Plague Tularemia
Most definitely! Our stomach contents are highly acidic, which not only helps to break down food but also destroy bacteria and other foreign agents that may harm us.
Unicellular infectious agents are prokaryotes, eukaryotes, bacteria, and protoza.
The skin and mucous membranes play a major role in protecting the body from diseases by keeping out foreign agents. There are also phagocytes, which are cells that "eat" pathogens which are harmful to the body. Another line of defense that our body has are the T lymphocytes, and the B lymphocytes which recognize foreign agents or particles called antigens and responds to them accordingly. The human body will also raise the temperature from 98.6 degrees Fahrenheit which is a perfect environment for bacteria to thrive, to a higher temperature of at least 100 Fahrenheit. This makes it harder for the bacteria to survive, this defense is most commonly known as a fever.
Some people are against antimicrobial agents because there is a school of thought that considers microbes and bacteria to be necessary to our health and hygiene. This is because introducing bacteria into our systems can help keep our immune system stimulated.

Better caontact to Agents.
Which agents? Agents carry whatever they are issued or allowed to carry by the local law in their municipalities, or by what is required by their organizations policies.
