Anatomico-physiological features

Leather. There is its thickening. But the unpleasant possibility of easily overcooling or overheating does not decrease.
Bone system. Her ossification is not yet complete. The spine already corresponds in shape to an adult, but only in shape. With the increased weight load on the fragile skeleton of the child, the control over his posture is more important than ever. Knowingly experienced grandmother angrily knocks her grandson on the shoulder blades, so as not to hunch, not stoop. Do not allow granddaughters to luxuriate for a long time in a soft armchair or comfortably "crouched" on the couch. For their beauty, a hard chair with a high straight back is preferable. Do not be tired of reminding yourself and them that scoliosis - the curvature of the spine begins at this age. From 3 to 7 years, the formation of the chest and respiratory organs is also completed. The ribs assume the same position as in adults, the thorax is a cylindrical shape. Breathing is deeper and more rare - by 7 years it reaches 23-25 ​​per 1 minute.
Cardiovascular system: the pulse continues to shrink. By the age of 7, his frequency is 85-90 per minute, blood pressure is 104/67 mm Hg. Art.
Endocrine system. At the age of 6-7 years there is some acceleration of growth, the so-called. The first physiological extension, at the same time, there are differences in the behavior of boys and girls. Active participation in these processes is taken by such glands as thyroid, adrenal, pituitary. The "preparation" of the sexual glands begins for the period of puberty.
Immune system: cells of immunity are produced by the body of the child in sufficient quantity, in connection with this - an easier course of many diseases.
Nervous system. The foundations of the intellect are laid. Children willingly remember poetry, draw with enthusiasm, amusingly compose, pereinachivaya heard fairy tales.
Little poets, artists, writers - "not attentive", but in fact a storehouse of potential creative opportunities - not for enthusiasm, but for close attention to them.
They are attached to the beginnings of morality, not just submissively accepting "doing well, but doing something bad", but also trying to comprehend "why?". As "parrots" repeat many actions of adults, choosing, as a rule, a model of close relatives.
To maintain a balanced, benevolent relationship - the best and wish everyone can not. And if you can not avoid the other, remember that in family "scenes" an extra witness is always a child.
