What is man made of?
�Man is a unique creature of nature. Our body can withstand the daily stress, stress and resists viruses. And it happens all the time! Many people ask: what is man made of? And this interest is quite reasonable.
�Man consists of water: how much?
�A person has a unique means by which we not only read this text, but also listen to the noises from the window and smell the delicious food. This is our brain. Unlike animal representatives, a person can reflect. This property has become central to human evolution. But not many people know that the human brain is responsible not only for our thoughts and feelings, but also for all the activities of the body. It is the brain that decides when you need to sleep, how to restore the body after heavy loads, and how to resist viruses that want to infect our body.
�Man consists of 80% of water. It sounds amazing, but it is. That is why doctors recommend drinking every day at least 2 liters of water every day. This recommendation is necessary for us to replenish our water reserves, which are consumed during the day, for example, when sweating.
�What does a human skeleton consist of?
�The human skeleton consists of many bones that are interconnected to form a support for our body. That is, thanks to the skeleton, we can stand on our feet, lie down, dance and do any other actions. Naturally, this is not so simple. Different bones are located in different parts of our body, which in each case are connected in such a way as to preserve the organs to the maximum and keep the person moving. What is the body of a man?
�The largest bone connection is the ribs. They are located just above the abdomen and reach the neck. The rib cage is made up of 12 large ribs, which are a �wall� for the protection of important organs such as the medulla, lungs and the main blood vessels.
�Another important part of our skeleton is the skull. The skull box protects our brain. The skeleton of our head consists of eight bones:
- ��Parietal bone.
- ��Temporal bone.
- ��Occipital bone.
- ��Swollen bone.
- ��Frontal bone
- ��The nasal bone.
- ��Upper browns.
- ��Lower jaw.
�How does the heart of man
�The heart is the main "machine" of our body. It serves to pump blood throughout the body.In a minute, when seated, it distributes about 5-6 liters of blood to our body. The heart muscle works constantly and changes its rhythm depending on the situation. When sleeping, the frequency of beats per minute is reduced, and with active sports activities, it can increase to two hundred beats per minute or more (depending on the person�s training). The more you move, the bigger your heart becomes, the more it pumps blood into your body.
�The heart consists of two atria and two ventricles, which are separated by valves. The valves are very important, thanks to them, our heart works correctly and "does not let the blood in the opposite direction." When one of the valves fails, the blood does not move as it should, which is the cause of heart disease.
�What is the human spine?
�The human spine consists of thirty-four vertebrae, which are connected to each other. Many people mistakenly think that the human spine is straight, but it is not. Our verteb is somewhat similar to the English letter S. In the cervical region, it bends slightly forward, and the thoracic is slightly curved backwards.
�In newborns, the spine is straight.Bends begin to appear with the development of the child. For example, cervical bending is made only one or two months after the birth of a child, or rather, when he learns to hold his head. When the baby is already quite adult and can sit, then a bend forms in the thoracic region. The rest of the bends appear after the child has already learned to walk.
�What is the nervous system
�The human nervous system consists of the spinal cord and brain. Nerve endings are located all over our body. For example, when you touch something, we feel this object. This happens due to the fact that the neurons passing through the nerve endings pass to our brain, and already the brain itself processing the signal lets us know what we touched and what we felt.
�Man is an amazing creature. Until now, scientists have not fully studied the functions of many of our organs. For example, it is still not clear how our brain works, how it manages to keep in itself so much information. To ensure that all your internal organs are always in order and without any kind of violations, visit doctors and undergo annual examinations.This will help you to pinch off many illnesses or to cure something seriously at the earliest stage of development, avoiding negative consequences.
