antigen | a protein and/or chemical that is foreign to our bodies. |
pathogen | are disease causing agents, such as viruses and bacteria |
pathogen | They are sometimes called germs |
bacteria | are Microscopic unicellular organisms that do not have a nucleus or other membrane-bound organelles (prokaryotes). |
pasteurization | is the process in which food is heated to a temperature that kills most harmful bacteria. It is based on the work of Louis Pasteur. (mid1800s) |
antibiotics | Bacterial diseases can be treated with |
antibiotics | are medicines that stop the growth and reproduction of bacteria |
virus | is a strand of DNA or RNA surrounded by a layer of protein that can infect and replicate in a host cell. |
virus | They are between 20-100 times smaller than bacteria |
host cell | 9. Viruses are not considered living things; they can replicate but must rely on a living organism to do so. The cell that the virus attaches to is called the ______. |
viral | Antibiotics do not work against _________infections |
communicable diseases | are also call infectious diseases |
pathogens | Communicable diseases are caused by _________________ that can be transmitted from one person to another. |
communicable diseases | The type of disease that may pass by direct contact, the exchange of blood or bodily fluids, indirect contact, or a vector. |
vector | a disease carrying organism that does not develop the disease. |
communicable | viruses and bacteria cause what type of disease? |
non-communicable | genetics,life style choices, and environment are the cause of what type of disease? |
cancer | is a disease in which cells reproduce uncontrollably without the usual signals to stop. |
immunity | means exempt or free |
passive immunity | this occurs when antibodies made in one organism are introduced into the body of another. This type of immunity comes from birth and/or a mother nursing a baby. |

antibody | substance made by an animal in response to an antigen. It attaches to the antigen/pathogen making it harmless. |
vaccines | are introduced to our bodies to give us active immunity from a disease without making us have the disease. Some are made in the lab with different compounds others are made from a weakened virus that cannot cause the disease or illness anymore. |
antibiotics | Used to treat and possibly cure BACTERIAL infections. Ineffective against viral diseases |
allergies | are over sensitive responses to a common antigen. If the body treats the antigen as a pathogen the typical immune response is mucus production and inflammation |
symptoms | are evidence of disease or of a patient's condition. |
prevention | to keep a person from getting ill because of a disease. |
treatment | refer to the ways we deal with a disease once they have been acquired. The management and care of a patient, or the combating of a disease or disorder. |
cure | something that relieves a patient of the symptoms of the disease or condition |
calorie | the amount of energy it takes to raise the temperature of water by 1◦ C. It shows how much energy food contains. |
protein | a large macromolecule that is made of amino acids and contains carbon, hydrogen, oxygen, and sometimes sulfur. |
carbohydrates | is a large macromolecule that is made of carbon, hydrogen, and oxygen atoms, and are usually the body’s major source of energy. |
fats | (also called lipids) provide energy and help your body absorb vitamins |
vitamins | nutrients that are needed in small amounts for growth, regulating body functions, and preventing some diseases. |
minerals | are inorganic nutrients that help the body regulate many chemical reactions |
