Cellular Structure and Function
What is the basic unit of structure and function?
The cell
These disease-causing agents are commonly called
What are Pathogens?
What is the transmission of Malaria?
Is the spread to humans through the bite of an infected mosquito
These three types of "foreign invaders" are what the immune system primarily works to defeat.
What are bacteria, viruses, and parasites?
This term describes a rapid, widespread increase in disease cases within a specific community, region, or population.
What is an epidemic?
Organisms that are made of one cell are called what?
Unicellular organisms
Smaller than bacteria, these agents require a living host cell to replicate and are not killed by antibiotics.
What are Viruses?
What is a disease?
A disease is any harmful, objective, and often measurable deviation from the normal structure or function of an organism's body or mind
This organ is responsible for filtering the blood
What is the spleen?
While an epidemic is localized, this term refers to one that has spread over multiple countries or continents, impacting a global population.
What is a pandemic?
Organisms that are made of multiple cells are called what?
Multicellular organisms
Fleas, ticks, lice, and tapeworms are all types of this kind of infectious agent.
What are Parasites?
Staying up-to-date with recommended COVID-19 vaccines and boosters.
Because medicine can't kill them, you use Tylenol or rest to treat this type of germ.
What is a virus?
This public health intervention separates people who have been exposed to a disease to see if they become sick.
What is quarantine?
What is the ribosomes in a bacterial cell use for?
The ribosomes are used for protein for the cell.
The most common example of a disease-causing agent
What is bacteria or a virus?
What is the definition of prevention?
Prevention involves infection control measures designed to interrupt the chain of transmission.
You use these to kill bacteria, but they don't work on viruses
What are antibodies?
This is the most effective long-term way to achieve "herd immunity" and prevent future waves of a disease.
What is vaccination?
What are the levels of organization from least broad to most broad?
Atom, molecule, organelle, cell, tissue, organ, organ system, organism.
What is the definition of a disease-causing agent?
A biological entity—such as a virus, bacterium, fungus, parasite, or prion—that invades a host and causes illness
What is the definition of transmission?
Transmission refers to the mechanism by which a pathogen is passed, resulting in infection.
This "Line of Defense" is made of physical barriers like skin and mucus
What is the First Line of Defense?
This system, used by the WHO, detects early signs of outbreaks to coordinate a unified international response.
What is a Global Health Surveillance System?
