Biomed - Practice Final Exam for Semester 2

The branch of medical science that deals with causes and control of health problems of a population:

• pathology

• entomology

• epidemiology

• histology

Any time an infection spreads across the world, it is considered a(n)

• epidemic

• outbreak

• endemic

• pandemic

Pathogen is defined as:

• an organism in which another organism lives

• a disease-causing organism

• a disease-causing organism taking up residence in its host

• a disorder in an organism that results in symptoms

non-living infectious agent (that causes the flu) needs a host to survive and cannot be treated with antibiotics

• virus

• prion

• fungi

• bacteria

• helminths

This living infectious agent (aka worms) is acquired through consumption of contaminated food or water and often causes rapid weight loss

• prions

• bacteria

• helminths

• viruses

• fungi

non-living infectious protein causes normal brain proteins to fold abnormally leading to neurological symptoms (confusion, hallucinations and eventually death).

• prions

• bacteria

• helminths

• viruses

• fungi

This living, multicellular infectious agent, which causes athlete's foot, includes mildews, molds and mushrooms

• prions

• bacteria

• protists

• viruses

• fungi

An infected individual pays at the grocery store with infected cash spreading the pathogen to the cashier. This form of disease transmission is an example of:

• direct contact

• droplet transmission

• indirect contact

• vector transmission

Malaria is spread through an intermediate insect that carries the pathogen: mosquitoes. This form of disease transmission is an example of

• direct contact

• indirect contact

• droplet transmission

• vector transmission

When infectious pathogens enter the body, the thymus produces these cells to release toxins and kill invaders

• B cells

• T cells

• vaccines

• antigens
