The Human Body: How It Functions
Our body is a temple that is complicated and extremely sensitive. It is a self regulating enigma of mechanism, which maintains its own internal cycle of organisation. It is capable of adjusting itself and work on its own authority, which makes attuned repeated processes, that regulates survival of essential properties inside the body.
Human Beings extract energy from their surroundings which is used for maintanance and survival, that takes place inside a cell. Each part of our body is composed with various types of cell, the number of cell accumulates to 37.2 trillion when it peaks maturity. The cells are formed together in a group into our organs and tissues which increases efficiency. The major source of energy to the human body comes directly from the sun.
Plants are also nurtured to form glucose-from water and the carbon dioxide in the air from sunlight. Other substances from the plant chemicals in the soil are also formed that are more complex, they can be used by man and animals as building materials, food-source, and energy supply which are taken up in amounts suited to the needs of the body.
Inside the human body is a long coiled tube of which the food enters, and serial chemical reactions break them down to be more easy to absorb and digest. It is then carried through a blood-stream and through to a closed branching system, of several tubes and tissues and organs throughout the body, which is broken up by chemicals and turned into energy source, that is stored as building materials for the human body.
Blood is distributed through the tubes, arteries and veins by a regular beating pump, which is the heart. The rate of which the heart beats is accurately in tune to the needs of the body, through a system of control. The chemicals which supplies energy to the body can do so only if there is a regular supply of oxygen distributed throughout the body.
We absorb oxygen from the air by blood which passes through two soft spongy organs our lungs, as soon as the oxygen is absorbed it is carried by blood in tissues where it is used. Huge amounts of carbon dioxide are passing through our lungs simultaneously as oxygen is absorb. Carbon dioxide and waste are continuosly formed by chemical reactions in the tissues, which is then excreted by the kidneys dissolved in the urine.
All of this is processed with exact accuracy and fragility. The chemicals and temperature of the body changes continuously, but are kept in effective harmony within limits by the elaborate control systems, which is describe as either a detector or receptor that responds to slight fluctuation of temperature chemistry, that sends messages to an effector that alters and adjusts as is needed.
The human body is engineered through the work of the nervous system, and through the course of evolution has evolved into many other functions, that matures to the highest point of communication and abstract thought.
