If you distribute the frequency of diseases that threaten the baby, then one of the first places will be pneumonia – pneumonia. This is an infectious disease of a bacterial or bacterial – viral nature, and any microorganisms, including even conditionally pathogenic ones, can cause it. And contact with them is almost inevitable for the child, and the whole question is whether his defenses will be sufficient to resist.
The condition of the child is closely related to the state of the mother, the course of pregnancy. If the mother suffers from some kind of inflammatory disease, the fetus comes into contact with the infection already in utero. This happens when he advances through the birth canal. Finally, the child was born, and the external environment, as a rule, is not free from germs. Microorganisms immediately populate the skin, umbilical wound, mucous membranes of the newborn. Propagating, they have an adverse effect on the body; Continue reading
The effect of cold on the entire surface of the body, when its temperature drops below 35 °, causes general cooling of the body. The prolonged action of low temperatures can lead to freezing, while the functions of the body are inhibited, up to their complete extinction. However, one should not think that during freezing the body temperature reaches zero. A person dies when his body temperature drops to 17 – 25 °.
The body becomes less resistant to cooling during starvation, significant fatigue, intoxication, getting into cold water, as well as after injuries, blood loss, It is noticed that hypothermia occurs faster in old people and children. High humidity, strong wind, especially if a person is dressed in light, tight or wet clothes, contribute to cold injury. Continue reading
Skin is an important and complex organ that performs various functions. It protects the body from external influences (mechanical, chemical, physical). Healthy and intact skin creates a reliable barrier to pathogens. She participates in the processes of respiration, excretion, thermoregulation; its role in metabolism and other vital processes is great.
The outer epidermal layer, or epidermis (I), is isolated in the skin. the skin itself – the dermis (II) and the subcutaneous tissue lying below it – the hypodermis (III).
The epidermis is formed by several dozen layers of epithelial cells lying one above the other. Its thickness is not the same everywhere, the thickest epidermis – up to 1.5 millimeters – has the skin of the soles, palms, and the thinnest – 0.03 millimeters – the skin of the eyelids. Continue reading
