Are you cold? Are you thirsty? Do you want to do? In such event has various control mechanisms in your body said on whether something is out of balance. The nervous system ensures that you'll have to take the necessary operations to maintain balance. You put on a jacket, drinking a glass of water, or take a ride on the pot. Mission accomplished! But you really had no choice. To maintain balance in the body is actually the most basic form of motivation.
A knowledge of the body's processes are smart if you want to develop. The more you know about yourself, the more you will have to find your weaknesses and work on those. This applies not only at the mental level, but also on the physical plane. Body and mind go hand in hand, and a comprehensive understanding is incredibly important.
I assume you sometimes think about your health. Humans generally have since time immemorial been keen to be fresh. A healthy person is considered more happy and more valuable than a sick person. He can also work more and create more value, so as to give of themselves and help even more people are doing well. This is important in a society.
Brief History
Being able to heal disease has been of interest as long as human history has existed. The concept of homeostasis is basically derived from physiology, but can be traced back to ancient philosophers Hippocrates' assumptions about the four essential body fluids (black and yellow bile, phlegm and blood). Disease was believed to result from an imbalance between these four bodily fluids.
In the middle of the 1800s, published the physiologist Claude Bernard's ideas on what he called "indoor environment". The theory was that the cells in the body rely on a stable internal environment for them to work properly and not die. The environment he was talking about is the fluid that surrounds the cells, known as extracellular fluid (ECV). This is eg. blood, lymph and plasma.
Besides might be on a constant level of volume and pressure, the extra cellular fluid having a constant temperature, constant mineral content (eg. Salt), constant content of water and a stable pH. The fluid must also be able to supply the cells the necessary energy, and transport waste products away from the cells. It must simply be a balance at all levels of ECV for the cells to function optimally.
Claude Bernard claimed so nice that "a constant internal environment is a precondition for a free and independent life." However, he had difficulty explaining how the body's systems failed to maintain this.
Walter B. Cannon (1871-1945)
The explanation would come a few years later, and in 1926 introduced the American physiologist Walter Bradford Cannon concept of homeostasis (equilibrium). In his book "The Wisdom of the Body", which he released in 1932, he explained how the human body is a self-regulatory mechanism controlled by a feedback system.
Homeostasis has been accepted as a doctrine of physiological processes, and is defined as the inner equilibrium which is necessary for the body's cells to function optimally.
Walter B. Cannon came up with a solution on how the body is able to maintain the important stable internal environment, despite the fact that it is located in an environment that is constantly changing. In the external environment, it is particularly temperature variable but also other environmental variations such as light, access to food and pollution.
The equilibrium is maintained through a partnership between the different cells, ie the body's organs.
The body and the cells
The cell
A prerequisite for organic life to exist are cells. Your body is made up of approx. Billiard one of them. A cell is in itself a self-contained breathing unit with particular characteristics. It is dependent on the supply of energy, it can reproduce itself and has specialized tasks. In a philosophical perspective, a cell is considered as a micro individual in its own environmental body, just as a man is a subject in its environment.
The cell's outer membrane (plasma membrane) is a kind of skin that keeps in place the cell's internal organs (organelles). Central to the cell's nucleus. It contains genes (genes) that determine which properties the cells get. A cell has thus the ability to store information that it transmits from generation to generation. (Paradox: Can a cell doctrine? Could the store new information? Has it something that can be considered memory? Someone actually mean it.)
A cell is made up of proteins. It uses most of the energy it receives (glucose) to form protein. Building block of protein are amino acids, which is cleaved by digestion of the food we eat. The cell uses protein to grow in size (vips! you have more muscle), or to reproduce (vips! You have a new skin for wound You incurred).
The cells are very vulnerable to change, and an imbalance in the extracellular fluid will cause them to not work properly. This will eventually result in illness and death in the worst case (read about darkness and natural reactions ).
The body's anatomy and physiology is on this basis designed to ensure an optimal internal environment, in relation to the environment it operates in. affinity with Darwin's theory of evolution is as you might guess, very present. It's all about adaptation and survival.
The body
This creature is dependent on a stable internal environment to develop normally.
In the first nine months after conception, the cells ensured an optimal environment in the mother's womb. After nine months the embryo is too large and must support themselves. When it's time to say goodbye to the stable environment of the uterus and embryos are born. A new body is born!
If the body should be able to exist independently of the uterus, it needs more organ systems. The cells therefore haste. Over the course of nine months, they work like whipped heavy lift workers and builds an unfinished edifice consisting of:
- Connective tissue system (including bones and skin)
- The nervous system
- The endocrine system (hormone production)
- Muscles
- Digestive system
- The lymphatic system (including immune system)
- The circulatory system (blood circulation)
- Respiratory
- Forplantningssytemet
All organ systems involved in the effort to maintain homeostatic equilibrium and systems communicate with each other. The nervous system, and to some extent the endocrine system, ensures that communication is as efficient as possible, with the central nervous system (brain and spinal cord) as supreme commander.
In this way the body's organs into a unified entity created for one purpose: to maintain balance in the internal environment to the cells (the body) can survive in the environment (eg. Jungle). An imbalance or disease in any of the organ systems, will have an impact on the rest of the systems and the body as a whole.
Since the body is only half done when it is born, the environment they grow up in a particularly crucial for further development. The environment outside the womb must maintain the new body's needs at all levels, physically and mentally. It must provide for maintaining the homeostatic equilibrium.
The body is not fully developed until after about 20 years, and the homeostatic processes will have a lot to say about how the structure will be. If the homeostatic equilibrium is much disturbed, the body will get permanent damage and may never be complete. The body as a survival strategy thankfully ability to adapt, and it can adjust the homeostatic equilibrium in step with changes in the environment. This is called "survival of the fittest," and they (the individual or the species) that are unable to adapt to environmental changes will eventually die out.
In some future articles I'll let the topic be balance. Balance is, in my opinion, is a universal principle that applies to all levels of the universe. It is the condition of ALT actually working against, and that is the key to peace and happiness of the individual and the world.
