The human body is the physical and material structure of the human being. It is studied by different branches of the biological sciences, depending on the organization level of the subject being analyzed.
Its constituent elements are hydrogen (H), oxygen (O), carbon (C) and nitrogen (N), with many other elements appearing in lower proportions. These atoms unite with each other to form molecules, whether they are inorganic like water (the most abundant constituent of our organism, 60%) or organic like carbohydrates, lipids, proteins, which make the human being an extraordinary complex, analyzable organism from any level: biochemical, cytological, histological, anatomical.
The human body is the set of physical structure and organs that make up the human being. The term human body originates from the Latin corpus, which means "body" and humanus, humanum which refers to "human". The physical structure is made up of three main parts: head, trunk and upper and lower extremities, and the structure referred to the organs is made up of different systems: circulatory, respiratory, digestive, endocrine, reproductive, excretory, nervous, locomotor.
The human body is also made up of chemical elements such as oxygen and hydrogen, vital for its functioning. Through different branches of the health sciences such as anatomy, biology, physiology and anthropometry, it has become known what the human body is, how it is shaped and how it works.
It is important, as individuals, to know how our body is formed and how it works, this in order to understand why our body constantly changes as we age and why we must take care of it through a balanced diet and physical activity. All human bodies are different, although their structure is the same, that is why human beings are individual beings, men and women have unique and unrepeatable bodies with different natural functions.
