The structure of human skin cells

From atom to human

To understand yoga it’s good to have an understanding of the working of the human brain and of the human body. In this blog we will look at the body: from atom to human.

A human is built out of:

  • Atoms – the smallest (stable) building blocks of the human body. They group together to form molecules.
  • Cells – Different molecules interact with each other to form bigger structures. Every structure has his own role in a cell. Together they form cells. Cells are the building blocks of all plants and animals. They are the smallest structural unit of an organism that is capable of independent functioning. They are created by cell division. They strive for homeostasis. Almost every cell has a kern. In this kern all information is stored that is needed for the cell to do its job. With yoga we can rewrite this information. Example: flexibility.
  • Tissue – A tissue consists of groups of cells who work together to do a specific function. For example: heart muscle cells form heart muscle tissue.
    There are four types of tissue: connective, epithelial, muscular and nervous tissue. Every structure (muscles, organs etcetera’s) in the human body consists of a combination of these tissues. Epithelial tissue covers the body’s surface and forms the lining for most internal cavities. The major function of epithelial tissue includes protection, secretion, absorption, and filtration. It gets replaced continuously. Connective tissue perform a variety of functions including support and protection for other tissues, transport (blood) and storage of energy (fat cells). Tissues found in the human body are ordinary loose connective tissue, fat tissue, dense fibrous tissue, cartilage, bone, blood, and lymph, which are all considered connective tissue. Every muscle is surrounded by a layer of connective tissue. The muscle can be flexible, but when the layer of connective tissue is tight it will prevent the muscle from stretching. With (yin) yoga we can work on the flexibility of this connective tissue. Muscle tissue can contract and makes movement possible. Nerve tissue receive stimuli but also conduct impulses and transmits these electric impulses through the whole body.
  • Organs – An organ consists of two or more different tissues who work together to do a specific function. For example the hearts, which consists of heart muscle tissue and other tissue, like nervous tissue. Together they pump blood through the veins.
  • Organ systems – Organs work together in organ systems. Every time our heart contracts, blood is pumped in a network of blood vessels. Heart, blood and blood vessels together form the circulatory system. 
  • Organism – All organ systems in the body work together and form an organism: in our case a human.
