Exogeneity can be deciphered as an external influence. The concept of "exogenous factors" is used in economics, mathematics, and medicine. Its meaning lies in external predetermination, the predetermination of any parameters, regardless of the functioning of the model against which they are considered. Endogeneity is the opposite term, carrying information about internal processes.
Definition of exogeneity in medicine
When describing exogenous factors, for example, in medicine, it is always taken into account that this influence is external. So, human he alth is affected not only by infections, the risk of injury, but also by social conditions. After all, proper nutrition, a he althy lifestyle directly depend on the income of the individual. So, this is also one of the factors of external influence on the body.
Variations in exogenous factors affecting he alth status can be as follows:
- human conditions in society, at home;
- presence or lack of preventive action;
- infections, injuries, medications taken.
Exo in Greek means "external", and genes -"spawned". 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 the outer, superficial.
Studying the conditions for the formation of he alth problems
The manifestation of exogenous factors is the action or influence of pathogenic microorganisms on the human body, causing various pathologies. The causes of the development of diseases are carefully studied, and based on the results of the research, mechanisms are developed to protect the patient from the influence of external adverse conditions. Thanks to preventive measures, dangerous pathologies are prevented.
External factors are divided into two groups:
- Factors of indirect action - this includes infections, viruses, diseases that lead to an inflammatory process, as a result of which the pathology in question is formed. Such, for example, is the effect of polluted water on the appearance of oncology.
- Factors of direct action - circumstances that directly cause the pathology in question. These are, for example, parasitic infections (Echinococcus, which causes proliferating cysts in the lungs).
It all depends on the point of view
Exogenous and endogenous factors are relative definitions, the semantic meaning of which changes depending on the point of view on the situation. Thus, the state of the environment becomes an external invariable condition for a person. If we consider the conditions for the occurrence of diseases in a separate organ, thenexternal negative reasons for the formation of pathology in it can also be violations of the digestive system.
And disruption of the endocrine system can be both an internal factor and an external one in relation to any area of the body under consideration.
Influence of exogenous factors on the occurrence of complications
When considering any pathology of the body, the external and internal conditions that led to the complication are always taken into account. By eliminating possible risks, it is possible to avoid the appearance of oncology, the spread of epidemics, and prevent the formation of incurable inflammations.
In this area of research, exogenous resistance factors - or otherwise the body's ability to resist environmental adverse conditions - occupy an important place.
External causes of complications are:
- mechanical;
- physical;
- biological;
- chemical.
Exogenous and endogenous factors affect the nervous, endocrine, circulatory, and lymphatic systems of a person. Immunity suffers first, and its weakening makes it possible to develop a huge number of pathogens. Therefore, when studying the sources of diseases, it is important to take into account all possible risks of complications.
External causes of disease
Exogenous etiological factors include the social conditions of a person: nutrition, lifestyle, the presence of stress conditions. For physical reasonsThe development of the disease includes: the influence of electromagnetic fields and radiation, burns from sunlight, deterioration of he alth at elevated ambient temperatures.
Mechanical exogenous factors include: various tissue and bone damage from direct contact with solid objects. Chemical include poisoning with poisons, vapors of harmful gases, bad food. Biological causes are the negative action of pathogens.
The most common damage to the body by parasites, bacteria, viruses, fungi. Infections are the most common cause of dangerous diseases. Modern medicine takes into account the risk of exogenous penetration of microorganisms into the body of a he althy person. To combat their spread, preventive measures are being taken: vaccines, isolation, timely treatment, raising the literacy of the population.
Internal causes of disease
When analyzing the risks of developing a disease, heredity is also taken into account. These are also exogenous factors. Examples of the transmission of pathology in hereditary ways are very common. Often chronic ailments are "recorded" genetically. And in adulthood, such people have a high degree of risk of developing diseases that their parents suffered from.
An exogenous factor is a predisposition to allergies, color blindness, malformations of internal organs, vascular thrombosis. Dangerous are hereditary syphilis, HIV infections, parasites. Such a sick person can pose a threatfor others.
An internal factor that can influence the formation of chronic diseases is age, gender, physical structure and body functions. Scientists share the causes of certain diseases in women and men. So, complications after pregnancy or sexual diseases in the stronger sex are considered in a separate vein.
The body's resistance to external threats
Given the causes of disease, it is important to compare exogenous risk factors with host resistance. Each person in a particular area of residence has a unique resistance to parasites and other infections. Over the course of their lives, such people develop stable immunity.
Exogenous factors become the most important for the analysis of pathological conditions. Unfortunately, external stimuli cannot always be fully taken into account, which causes oncology, disability and even death of a person. But endogenous factors often cause early death.
