Characteristics of exogenous factors

Exogenicity can be deciphered as an external effect. The term "exogenous factors" is used in economics, mathematics, and medicine. Its meaning is in the external predetermination, the prescription of any parameters, regardless of the functioning of the model against which they are considered. Endogenicity is the opposite term, which carries information about internal processes.

Determination of exogeneity in medicine

When describing exogenous factors, for example, in medicine, it is always considered that this influence is external. So, human health is affected not only by infection, the risk of injury, but also social conditions. After all, proper nutrition, a healthy lifestyle directly depend on the income of the individual. So, this too is one of the factors of external influence on the body.

Variations of exogenous factors affecting health can be as follows:

• The conditions of human life in society, at home;
• Presence or absence of preventive actions;
• Infections, injuries, medications taken.

Exo in Greek means "external", and genes - "generated." And most often this term is used in scientific works in the study of diseases or other problems. So, in biology, the exogenous layer of tissues is understood as external, superficial.

Studying the conditions for the formation of health problems

The manifestation of exogenous factors is the effect or influence of pathogenic microorganisms on the human body, causing various pathologies. The causes of the development of diseases are carefully studied, and according to the results of the research, mechanisms are developed to protect the patient from the influence of external unfavorable conditions. Due to preventive measures, dangerous pathologies are prevented.

External factors are divided into two groups:

1. Factors of indirect effect - here include infections, viruses, diseases that lead to the inflammatory process, as a result of which the pathology under consideration is formed. Thus, for example, the effect of contaminated water on the onset of oncology.
2. Factors of direct action are the circumstances directly causing the pathology in question. These are, for example, parasitic infections (echinococcus, which causes growing cysts in the lungs).

Everything depends on the point of view

Exogenous and endogenous factors are relative definitions, the meaning of which varies depending on the point of view on the situation. So, the external condition for man is the state of the environment. If we consider the conditions for the occurrence of diseases in a separate organ, then external disturbances in the formation of pathology in it can also be a violation of the digestive system.

A disruption of the endocrine system can be both an internal factor and external to any considered area of the body.

The influence of exogenous factors on the occurrence of complications

When considering any pathology of the body, external and internal conditions that lead to complication are always taken into account. Excluding possible risks, you can avoid the oncology, the spread of epidemics, prevent the formation of incurable inflammations.

In this area of research, an important place is occupied by exogenous factors of resistance - or otherwise the possibilities of resistance of the organism to surrounding unfavorable conditions.

External causes of complications are:

• Mechanical;
• Physical;
• Biological;
• Chemical.

Exogenous and endogenous factors affect the nervous, endocrine, circulatory, and lymphatic systems of man. The first to suffer from immunity, and its weakening gives the opportunity to develop a huge number of pathogens. Therefore, when studying the sources of diseases, it is important to consider all possible risks of complications.

External causes of diseases

Exogenous etiological factors include human social conditions: nutrition, lifestyle, the presence of stressful conditions. The physical causes of the development of the disease include: the influence of electromagnetic fields and radiation, sunburn burns, deterioration of well-being at elevated ambient temperatures.

To mechanical exogenous factors include: various damage to tissues and bones from direct contact with solid objects. Chemicals include poisoning with poisons, vapors of harmful gases, poor food. Biological causes are the negative effects of pathogens.

The most common lesions are parasites, bacteria, viruses, fungi. Infections most often cause dangerous diseases. Modern medicine takes into account the risk of exogenous penetration of microorganisms into the body of a healthy person. To combat their spread, preventive measures are taken: vaccines, isolation, timely treatment, and increasing literacy of the population.

Internal causes of diseases

When analyzing the risks of developing the disease, heredity is taken into account. These are also exogenous factors. Examples of the transmission of pathology by hereditary pathways are very common. Often, chronic ailments are "recorded" genetically. And in adulthood, such people develop a high degree of risk of developing diseases that parents suffered.

Exogenous factor is the predisposition to the disease for allergy, color blindness, defects in the structure of internal organs, thrombosis of blood vessels. Dangerous are hereditary syphilis, HIV infection, parasites. Such a sick person can pose a threat to others.

An internal factor that can influence the formation of chronic diseases is age, gender, physical structure and functions of the body. Scientists share the causes of the appearance of certain diseases in women and men. So, consider in a separate key complications after pregnancy or sexually transmitted diseases in the stronger sex.

Resistance to external threats

Given the causes of disease, it is important to compare exogenous risk factors with the resistance of the body. Each person in a particular locality has a unique resistance to parasites and other infections. During a life at such people the stable immunity is formed.

Exogenous factors become the most important for the analysis of pathological conditions. Unfortunately, external stimuli can not always be fully taken into account, which causes oncology, disability and even death of a person. But endogenous factors often lead to early withdrawal from life.
