What Is Pathophysiology ? | What’s The Definition Of Pathophysiology With Meaning




Pathophysiology is a modern integrative biomedical science founded on basic and clinical
research concerned with the mechanisms responsible for the initiation, development, and
treatment of pathological processes in humans and animals. There are two separate medical fields involved in pathophysiology. The first is physiology, the study of the body and its functions.

The second is pathology, the study of disease and its impact on the body. When
combined, pathophysiology means to know the way in which a disease progresses and to
predict the next stage of a disease, which provides appropriate care to the patient.

Pathophysiology is ‘the study of the changes of normal mechanical, physical and
biochemical functions, either caused by a disease or resulting from an abnormal syndrome’.
When something disrupts normal physiological processes, it enters the realm of

It looks at the specific malfunctioning that comes from or alternately
causes disease. The study of pathology and the study of pathophysiology often involves
substantial overlap in diseases and processes, but pathology emphasizes direct observations, while pathophysiology emphasizes quantifiable measurements.

An example from the field of infectious disease would be the study of a toxin released by a bacterium, and what that toxindoes to the body to cause harm, one possible result being sepsis. Another example is the study of the chemical changes that take place in body tissue due to inflammation.

Following are important aspects among pathophysiology and related subjects.

What Is Biology ?

Biology is a natural science. It is
the study of life and living organisms,
including their structure, function, growth,
evolution, distribution and taxonomy.
Pathological processes begin frequently at
the cell level.


What Is Biochemistry?

Biochemistry is the branch
of science that explores the chemical
processes within and related to living
organisms. It is a laboratory based science
that brings together biology and chemistry.
By using chemical knowledge and
techniques, biochemists can understand and
solve biological problems. Biochemical
processes are changed under pathological


What Is Anatomy and histology?

 Macro and micro structural properties of the human
body are essential for understanding their


What Is Biophysics?

Biophysical properties of cells, tissues and organs determine their
structural and functional characteristics.

What Is Physiology?

It is the branch of biology dealing with the functions and activities of
living organisms and their parts, including
all physical and chemical processes. It is
helpful to recognize pathologic functions


 What Is Pathological anatomy?

The ultrastructural and macro structural changes under
pathological conditions help to understand
functional changes and vice versa.
Microbiology and immunology: It
helps to understand the mechanisms
involved in development of disease caused
mainly by pathogenic micro-organisms and
disorders of immune system.

What Is Etiology?

Etiology is a branch of medical
science dealing with the causes and origin
of diseases 


What Is Pathogenesis?

Pathogenesis means the
gradual development of a disease and the
chain of events leading to disease in
response to etiologic factor.

What Is Clinical manifestations?

These are the observable symptoms by which a disease
may be diagnosed by a physician. Clinical
presentations are the whole package of the
disease process including epidemiology, history, physical examination and laboratory
tests etc.

What’s The Need of pathophysiology study?

It helps the health care professionals to find answers to important questions related to
disease processes:

  • What are the cause/causes of the disease, and why the disease is developing?
  • What are the mechanisms responsible for disease onset, progression and recovery?
  • What are the mechanisms responsible for development of symptoms and signs of disease?

It is important to understand the causes
and mechanisms of the disease to find the
way how to treat them safe and effectively.
In the clinical setting, pathologists,
histotechnologists and cytotechnologist
study tissues and cells to establish the cause
of a disease. Physicians use that information
to form a treatment plan.

Pathophysiology is a required area of
study for nearly all healthcare professional
school programs (medical, dental, physician
assistant, occupational therapy, physical
therapy, nurse practitioner, pharmacy,
nursing, and paramedic programs) in the
