Learn so much about your body

No matter how much modern science advances, no matter how many new discoveries are made, but the complex structure of the human body is probably the best in the world. Many organs of the body are active day and night to keep the body alive and provide the energy needed for all the functions. Twenty-four hours a day. We eat on Saturdays and Sundays, but our lungs, heart, brain, blood, etc., have been doing their job since we were born - without a second's rest. And if any one of these organs stops its operation, it is certain to reach our hospital. Come, today we know in this article some wonderful secrets of the human body.

What happens to the body in 1 minute?

In everyday life we think a minute is very normal, but everything that happens in our body in this one minute is wonderful and complex.

The heart beats 40 times a minute.
We breathe an average of 15 times.
We use about 5 to 6 liters (0.3 cubic feet) of air for breathing.
6 liters of blood circulates in the blood circulation area of thousands of kilometers of our body.
120 million red blood cells are created every minute inside the body's bone marrow. And the same number of red blood cells are destroyed.
Our eyes blink 70 times.
And yes, the activity of digestion and the conversion of food into glucose is always ongoing.

Do body parts change?

Our bodies grow with age. It is natural to have a change in appearance, but it would be surprising to know that some internal organs are completely changed. As such, the gastric lines inside the abdomen change every three days. Our skin peels off every month, and new ones come along. Every ten years the skeleton of our body changes. However, the pacemaker cell that controls the heartbeat stays with us for the rest of our lives. Meaning it never changes.

Body temperature

Our normal body temperature is 4 degrees Celsius, neither higher nor lower. If the body temperature rises by four degrees, the person may feel dizzy and faint. And if the body temperature has risen seven degrees, death is certain. In the external environment, even if the temperature rises by 3 degrees or in cold weather the figure reaches minus, the body temperature will remain the same. Sweating occurs when there is more heat. Sweat absorbs heat, and it evaporates. This way protection against heat and temperature are maintained.

When it is very cold, the hairs stand on end and the body parts start moving and trembling. Which causes an attempt to generate heat, but the physical response to protect against the cold is not so effective. (So we have to use jackets, shawls, blankets, heaters, etc.) When the body temperature drops, the blood circulation is affected and the blood vessels begin to constrict, so that the blood can circulate properly, but this condition is more frequent. Has the opposite effect. Hypothermia affects the killer cold, in which a person may initially lose consciousness, become unconscious and even die in a severe condition.

Heart function

From the time a baby is 9 weeks old in the mother's womb, the human heart begins to beat until the very last breath. The function of the heart in the body is to circulate blood. When the heart swells, blood enters it, and when it contracts, it carries blood to other parts of the body. Blood travels through the valve inside the heart. The opening and closing of which causes a ‘lub-dub’ sound. Which we call the heartbeat.

Normally the heart beats at 60 beats per minute, but when we work harder the body's organs need more oxygen and blood so the heart's functioning increases. As a result, the rate of valve opening and closing also increases and our heart rate also increases, which may be more than 150. The human heart beats 1 million times a day and an average of 3 million times a year.
Blood circulation

The function of the blood in the body is to deliver energy oxygen and glucose to every organ. Oxygen received during respiration is absorbed into the bloodstream through the lungs. In addition, the food we consume is converted into glucose, which provides enough energy to every part of the body through the blood. The main component of blood cells is hemoglobin, which carries oxygen.

White blood cells create red blood cells and protect the body against disease and impurities. In our bone marrow, white blood cells nourish red blood cells within themselves and produce new red blood cells every five days. The number of blood cells in the body is 3 trillion. (1 trillion, that is, 1,000,000,000,000,000) These blood cells are made to reach all the blood vessels in the body. If we connect all the blood vessels of the body in a straight line, it becomes approximately one lakh kilometers. Through which the earth can be rotated twice. The lifespan of red blood cells is about four months. It reaches the dying bone marrow, where white blood cells destroy it..

The brain is the most complex

The most complex structure in the entire universe, if any, is the human brain. The brain manages every function of our body. Responds, senses and stores memory. The brain weighs about 2% of the body weight, or about 1 kg 50 grams, of which 90% is fat, but 80% of the energy produced inside the body is used by the brain.

This energy is used to keep brain cells healthy and to manage the nervous system. The number of neurons inside the brain is about 100 billion, which is 12 times the total population of the world.

If blood does not reach the brain for 8 to 10 seconds, it becomes unconscious and if oxygen does not reach for 5 minutes, the brain is permanently damaged. The speed of signals traveling from different parts of the body to the brain is 215 kilometers per hour.

All the good and bad memories of a lifetime are stored in our minds. Scientists have shown that the memory storage capacity of the brain is 4.5 petabytes, if we convert it to megabytes, it becomes 2,6,8,8,20 megabytes.

Many people say that we use 10 percent or less of our total brain capacity. This is completely unfounded because every part of the brain has a specific function, and every part manages every function.

The heart as well as the brain take shape after the third week when the baby is in the mother's womb. About 8,000 brain cells are formed every second before birth, and by the time they are born, all of our lifelong brain cells have been formed.
