Health vs. Disease Flashcards
What is physiology
The way a living organism and its components function normally
What is structure?
The way a human body is put together
Define pathophysiology
The structural and functional changes that occur because of an injury, disease, or disorder
What is health?
Physical, mental, and social well-being
If you are not sick are you healthy?
No, health is not just absence of disease but also presence of well-being
Define disease
A deviation from normal structure or function of 1 or multiple body structures
Does disease have to have a known cause?
No, it can have no known cause, multiple causes, or a known cause
What is the difference between a disease and a syndrome?
A syndrome has a predictable pattern and characteristic manifestations of signs and symptoms. A syndrome may even have multiple diseases as its presentation. A disease describes the actual impaired structure or function
What does etiology mean?
The cause of a disease
What does a multi factorial etiology mean?
Multiple factors or events can cause or contribute to a disease?
What is an example of a multi factorial disease?
Alzheimer’s disease
What is an idiopathic disease?
A disease with no known etiology
What is a nosocomial disease?
A disease caused by exposure to a healthcare setting
Give an example of a nosocomial disease
A bacterial infection after a stay in the hospital
What is a Iatrogenic disease?
A disease that is caused by a medical treatment
What is the difference between a nosocomial disease and an iatrogenic one?
A nosocomial disease is caused by exposure to a healthcare environment and a iatrogenic disease is actually due to the treatment. For example, a drug that has hypotension as a side effect would be iatrogenic not nosocomial
What is pathogenesis?
How a disease process evolves
What is a risk factor?
Something that increases the probability of experiencing a adverse health outcome
What is a precipitating factor
An agent that promotes or triggers a clinical manifestation
Compare sign and symptom
A sign is objective and observable. A symptom is subjective, unverifiable, and reported by the patient
What is a local disease
A manifestation is only found in one body area near the site of the disease
Define systemic
Manifestations are present throughout the body and are not confined to one area
What is an acute condition?
A condition that begins abruptly and only lasts a short time
What is a chronic condition?
A condition that begins slowly and lasts a long time or never goes away
