Question

Pathophysiology is the
A. Study of the physiology of pathogens.
B. Study of the normal physiology of the host.
C. Study of altered physiology of the host.
D. None of the above.

Answer 1

Hint: Pathophysiology is associated with the study of functional change in the body of host due to any kind of disease, injury, syndrome or infection is called pathophysiology. Due to alteration in the functional change in the body of the host behave differently.

Complete step by step answer: Pathophysiology is the convergence of pathology and physiology. physiology is the study of the altered physiological process which occurs due to disease or injury, physiology describes the process or mechanism that occurs in the body of an organism while pathology describes the situation that typically occurs during ill state or abnormal condition.
Example:
1. The pathophysiology of heart failure defines the reduction of in functioning of heart muscle due to damage or overloading, which occur by various reasons such as myocardial infarction, hypertension, amyloidosis.
2. The pathophysiology of HIV/AIDS, occurs due to infection of the AIDS virus in the body which kills the natural defense system of the host body, which results in an infestation of several microbes in the body of the host that cause various diseases. AIDS causes the deficiency of Cell-mediated immunity which causes a syndrome in the body.
3. The pathophysiology of Obesity:- it involves the several pathophysiology conditions which are related to development and maintenance. Basically in obesity, a person suffers overweight, which creates several health-related problems such as heart-related disease, alteration of the blood sugar level, skin disease, problem in movement of the body due to being overweight.
Hence the correct option is C.

Note: The Pathogenesis creates the pathophysiological condition, in which pathogen causes disease in the host body which can describe the origins and development of disease whether it is chronic or acute, and their types such as microbial infection, inflammation, tissue damage, and malignancy.
