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.
Definition 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, healthy lifestyle directly depend on the income of the individual. So, this is also one of the factors of external influence on the body.
Variations of exogenous factors that affect health status can be as follows:
- the conditions of a person's life in a community, 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 outer, superficial.
Study of 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 the results of research develop mechanisms for protecting the patient from the influence of external adverse conditions. Due to preventive measures, dangerous pathologies are prevented.
External factors are divided into two groups:
- Indirect factors - this includes 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 appearance of oncology.
- Factors of direct action are the circumstances directly causing the pathology in question. These are, for example, parasitic infections( echinococcus, which causes expanding cysts in the lungs).
Everything depends on the point of view of
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 onset of diseases in a separate organ, then the disturbances in the digestive system may become external negative causes of the formation of pathologies in it.
A disruption of the endocrine system can be either an internal factor or external to any considered area of the body.
Influence of exogenous factors on the occurrence of complications
When considering any pathology of the body, always take into account the external and internal conditions that led to the complication. 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 a person. 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 take into account all possible risks of complications.
External causes of diseases
Exogenous etiological factors include human social conditions: nutrition, lifestyle, stress conditions. The physical causes 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, bad food. Biological causes are the negative effects of pathogens.
The most common lesions of the body 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.
An exogenous factor is a predisposition to an allergy, color blindness, defects in the structure of internal organs, and 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 of the body to external threats
Given the causes of diseases, 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 lifetime such people develop a stable immunity.
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.
