What Is Child Development?

Growth refers to the growth and morphological changes of various organs and systems of the body, and changes in quantity; development refers to the differentiation and perfection of cells, tissues and organs, and functional maturity, which are qualitative changes. The two are closely related. Growth is the material basis for development, and developmental maturity is reflected in changes in the amount of growth. Human growth refers to the maturation process from fertilized eggs to adults. Growth and development are important characteristics that distinguish children from adults. Growth refers to the growth of children's various organs and systems, and corresponding measurement values can be used to indicate changes in their quantities; development refers to the differentiation and functional maturation of cells, tissues, and organs. Growth and development are closely related. Growth is the material basis of development. Changes in the amount of growth can reflect the maturity of body organs and systems to a certain extent.

Nutrition is the material basis to ensure the normal growth and development of children and physical and mental health.

Physical growth in this period from 4 to 6 months is slightly higher than the first three months of life

The factors that affect children's growth and development are as follows:

I. Genetics: Genetic factors have a certain effect on the growth and development of children. For example, the height of the parents, the color of the skin, the amount of hair, and the shape all affect the children to a certain extent.

2. Mental factors: Children who cannot be cared for by experts believe that

The fat, protein, sugars and other nutrients that the human body eats must be decomposed by various digestive enzymes before they can be absorbed and used, a large part of which is selenium-containing enzymes. If the human body is deficient in selenium for a long time, it will cause digestive and absorption dysfunction of the human gastrointestinal tract, cause delayed growth or stagnation of the human body, and low immunity.

Trace elements are classified relative to major elements (a large number of elements), and can be divided into multiple types according to the different objects. At present, there are mainly two types of attention, one is trace elements in organisms, and the other Trace elements in nonliving organisms (such as rocks).
