There are many reasons and risk factors for a decrease in immunity. A transient decrease in immunity is caused by insufficient protein and energy nutrition, a deficiency in the consumption of micronutrients, especially vitamins A, C, E, D, β-carotene, essential trace elements (zinc, iron, selenium, iodine), polyunsaturated fatty acids, the presence of chronic digestive diseases history of infectious diseases, taking antibiotics, exposure to environmental pathological factors, impaired intestinal microflora. Inadequate protein and energy intake are known to reduce antibody synthesis. Deficiency in the diet of polyunsaturated fatty acids, vitamins A, C, β-carotene, zinc is accompanied by disorders in all parts of the immune response. Iodine deficiency reduces the activity of the phagocytic link, components of antioxidant protection (vitamins A, E, zinc, selenium, etc.), adversely affects the functional activity and vital activity of immunocompetent cells. Many acute and chronic diseases negatively affect immunity, which significantly reduces the child’s resistance to infection and other damaging factors. Continue reading
Rubella is a viral infectious disease that is transmitted by airborne droplets. Rubella is characterized by a slight swelling of the lymph nodes. A pinkish-red rash appears on the body. Rash on the skin can be accompanied by an increase in body temperature, aggravation of the respiratory tract. The incubation period lasts for 11-23 days. Treatment. The patient should adhere to bed rest. If the body temperature has risen, it is necessary to use antipyretics, and antihistamines should be used for redness on the skin.
Whooping cough is an infectious disease that is transmitted by airborne droplets and a severe cough appears. The incubation period is from 3 to 14 days. The cough is spasmodic, with mucus secreted. An acute period occurs during the first week of illness. Treatment. Doctors prescribe antibiotics, inhalations, bronchodilators. The patient often needs to be in the fresh air, especially near ponds and in the morning. Continue reading
The structure of the human respiratory system The human respiratory system consists of tissues and organs providing pulmonary ventilation and pulmonary respiration. In the structure of the system, it is possible to distinguish the main elements – the airways and lungs, as well as auxiliary – elements of the musculoskeletal system. The airways include: nose, nasal cavity, nasopharynx, trachea, larynx, bronchi and bronchioles. The lungs consist of alveolar sacs, bronchioles, as well as arteries, capillaries, veins of the pulmonary circulation. Elements of the musculoskeletal system associated with breathing include ribs, intercostal muscles, the diaphragm, and auxiliary respiratory muscles. Numerous studies carried out in various countries have shown a significant increase in respiratory diseases over the past 10 years.
Types of respiratory diseases. Bronchitis is an infectious disease accompanied by diffuse inflammation of the bronchi. The main symptom of the disease is a cough. If the disease lasts less than three weeks, they speak of acute bronchitis. Continue reading
