How do people grow? Why do people stop growing?
When a small child is born, Lakka becomes young. Becomes a great man. If this process of growth continues unabated, it will reach 10-12 feet by the age of 40-50! But that is not the case. At the age of 20-22, the growth of people stops. Why does this happen?
How do people grow?
Every living thing grows. Each living thing grows based on its size, type and texture and the activity they perform.
Heredity plays a major role in the growth of living things. Accordingly, every animal, plant and other biological substance, including humans, has its own time period of growth. These include fetuses, newborns, childhood, adolescence, adulthood, and old age.
This process of re-growth also tends to be different in different creatures and living things. For example, some species of birds can fly as soon as they are born. Guinea pigs are able to take care of themselves within three days of birth. But that doesn’t happen immediately in humans. It takes a certain amount of time for people to play and take care of themselves.
A newborn baby has all the nervous systems in the body, including the brain and spinal cord that a person should have. As well as the growth of other parts of the body, the growth of these nervous systems enables people to control their activities, learn and behave like other people in their society.
Again, every person grows in the same way. But this order and style of growth is slightly different in boys and girls.
As people grow, they grow not only in height but also in width. Initially, a person’s height increases for a while, then his width increases. This sequence continues. In most people, the width increases at the age of 11 to 12 years. In this case, people look a bit fat and fat. But then the height of the body starts increasing again and that vanity disappears.
In the early weeks of life, a person’s physical growth rate is much faster than at other times. By the first year of life, the intensity has decreased. However, the growth of people continues at a reasonable rate throughout childhood. Then the intensity starts to increase again.
When a girl reaches the age of 11 to 13, her physical growth accelerates. Similarly, in boys, this intensity occurs at the age of 12 to 14 years. This process of physical growth goes very fast to a certain extent of growth. And, then again, it gradually decreases in intensity, but the body continues to grow. This process of physical growth continues until a certain limit is reached.
As people grow, not only height, but also width. Initially, a person’s height increases for a while, then his width increases. This sequence continues. In most people, the width increases at the age of 11 to 12 years. In this case, people look a bit fat and fat. But then the height of the body starts increasing again and that vanity disappears.
In humans, the process of growth has been going on since the womb. It is not only through this process of growth that a person grows in size and height, he also attains adulthood. A person’s physical growth and adulthood depends not only on the internal system that produces the various hormones that make his body grow, but also on his diet and the vitamins and nutrients he receives.
The embryonic stage is the primary stage of human growth. During embryonic development, the embryo may grow from 45 grams to 3,500 grams. At this stage, fetal growth is dependent on hormones called insulin and thyroxine.
After the birth of a child, the process of physical growth begins to accelerate. In this case, the parts of a person’s body grow much faster than the head. The main reason for this is that most parts of the human brain have already developed in the mother’s womb before the baby is born. But even after a person is born, the brain cells are not fully developed. Even after birth, brain cells continue to develop, the speed of which depends on the hormone thyroxine. In addition to the brain, the heart, liver, lungs, immune system, reproductive system and other important organs of the body that have been developed before birth are also developing and maturing.
Apparently by the age of 15 our body size is increasing rapidly. This is because of the increased activity of growth hormone. In this condition, especially the bones of our body develop and become strong. This process continues until the age of about 25. In addition, some organs, such as the liver and bones, may continue to grow or develop over the course of a lifetime due to injury or other similar conditions.
Why do we stop growing?
After a certain period of time, that is, after reaching the age of 20-22 years, it slows down and at the age of 25, our physical growth rate stops. At birth, the baby grows from 50-60 cm to 1.7 m. Then it does not increase. Why does this happen? Why and how do people stop growing and growing bigger?
