Pathogens and Disease10 Points

What is the difference between a preventative measure and a reactionary

measure?

Answer:Preventative Measure: proactive; thwarts a pathogen from making us ill (ex. Flu Shot)Reactionary Measure: kills a pathogen that is already doing damage.

What is the difference between an antibiotic and a vaccine?

Answer:Antibiotic: reactionary measure; treats bacterial infections already in our body.Vaccine: preventative measure; usually a dead or weakened versions of a virus to help our bodies build up immunity.

What is the Germ Theory?

Answer:Illness is caused by pathogens (microscopic organisms called germs) mainly contagious. Not all diseases are “germs”, some are genetic and/or caused by mutations

What is the Miasma Theory?

Answer:“Bad air”, poisonous vapour filled with particles from garbage caused ilnesses. Physicians and the rich wore masks that contained fragrant herbs so they could not smell the “bad air.” The solution was to isolate the sick, dirty and poor

Pathogens and Disease50 Points

If you were in a room with several people, what are four ways a pathogen can be

transmitted?Answer:1)Airborne: pathogens in the air that we breathe in.2)Droplet Contact: pathogens that travel through the air by cough or sneeze.3)Direct Contact: an infected person with signs of infection touches someone that isn’t infected.4)Indirect Contact: an infected person touches a surface and leaves the pathogens there.

Science and Public Health 10 Points

What are the two characteristics of public health?

Answer:1)Deals with preventative rather than reactionary measures.2)Deals with population-level health issues, not individual level ones.

What is C.difficile?

Answer:Clostridium difficile is a bacteria that becomes a problem when it overpopulates our intestines and drives other helpful bacteria out. Over population is harmful because they release toxins that can cause bloating , constipation and diarrhea.

Identify the three types of digestive disorders and give an example of

each.Answer:Structural – physical abnormality (ex. Hiatus Hernia)Malabsorptive – problems with nutrient absorption (ex. Lactose Intolerance)Inflammatory – causes swelling and/or bleeding (ex. Crohn’s Disease)

Nutritional Science 40 Points

What are the four stages of food processing?

Answer:1)Ingestion – Taking in food2)Digestion – Breaking down food into nutrients3)Absorption – Taking in nutrition by cells4)Egestion – removing leftover waste

Nutritional Science 50 Points

What are the steps of the digestive system?

Answer:1)Mouth – physically breaks down food.2)Throat – pushes food into stomach by peristalsis. 3)Stomach – chemically breaks down food. 4)Small Intestine – majority of nutrient absorption.5)Large Intestine – absorbs water from waste material.6)Rectum – all leftover waste is compacted and excreted through the anus.
