Levels of organization within the human body

The body is highly organized.The simplest level of organization is the chemical level,consisting of atoms and molecules.All matter is composed of chemical elements -pure chemical substances like iron,calcium or oxygen.About 98% of the human body is composed of 6 elements-oxygen,carbon,hydrogen,nitrogen,calcium and phosphorus.An atom is the smallest amount of a chemical element that has the characteristic properties of that element.Atoms can combine chemically to form molecules.For example,two atoms of hydrogen chemically combine to form one molecule of water.

Atoms and molecules associate to form the organelles and cells(building block of the body)of the cellular level.The human body is composed of about 100 trillion cells of many types,such as bone cells,muscle cells and blood cells.Cells vary in size and shape according to their function,most of them are so small that they can be seen only with a microscope.Each cell consists of specialized cell parts called organelles.One organelle,nucleus,serves as the information and control centre of the cell.Several other kinds of organelles scattered throughout the cell perform specific functions like breaking down fuel molecules to provide energy and manufacturing needed substances.

Cells associate to form tissues such as muscle or bone tissue.A tissue is a group of closely associated cells specialized to perform particular functions.The four main types of tissues are muscle tissue,nervous tissue,epithelial tissue and connective tissue.

Tissues may be organized to form organs such as the brain or heart.The heart consists mainly of muscle tissue but it is covered by epithelial tissue and also contains connective and nervous tissue.

Certain tissues and organs function together to make up an organ system or a body system.For example,the circulatory system consists of the heart,blood vessels,blood,lymph structures and several other organs.

The body systems work together to make up the human organism.

Potassium and Its Benefits to the Human Body

Potassium is a mineral that serves a variety of purposes within the body. Despite its importance to so many of the body's functions and systems, most people do not consume the standard recommended daily levels of this essential mineral. This is unfortunate as long-term deficiency can contribute to and even directly cause a variety of health problems and complications not only to the body but to one's lifestyle as well.

Helping to regulate the body's fluid levels is one of the mineral potassium's greatest functions. Not only that but it also has a great part in regulating the blood pressure. It also helps to keep the heart thumping steadily and regularly and is also essential to the nervous system. Potassium works to promote the proper functioning of the tissue that makes up the nervous system. It also serves to enhance muscle control plus the growth and health of cells particularly through its importance in waste product removal. This mineral is also vital to the kidneys in their waste removal tasks. Potassium also plays an important role to mental function as well as to physical processes. It helps to promote efficient cognitive functioning by playing a significant role in getting oxygen to the brain.

Failing to meet the standard recommended daily intake levels can lead to a variety of negative consequences for both physical well being and mental health. Physical symptoms can include muscular cramps and twitching, muscular weakness, even actual muscle damage, poor reflexes, fatigue, fragile bones, irregular heartbeat and other cardiovascular irregularities, kidney failure, lung failure, and cardiac arrest. Mental symptoms can include nervous disorders of various types, anorexia, insomnia, a slowdown of cognitive processes, and depression.

There are certain health situations that can make a person more susceptible to suffering from a deficiency of potassium. These include alcoholism, health conditions requiring the use of certain types of diuretics, periods of high stress and illnesses or conditions that result in extended periods of diarrhea and vomiting. Some situations of our own making can contribute to potassium deficiency. These include excessive caffeine intake and a diet made up of mostly processed foods. Consuming excessive amount of salt daily can also attribute to the decrease of potassium in the human body.

Our bodies are complex systems in which there is a delicate chemical balance that keeps everything functioning as it should. Disruptions to the system are going to have consequences with some being more severe than others. Some of these consequences can take the form of disease or irreversible damage. Prevention is always better than trying to cure illness or repair damage. One of the most important parts of prevention is good nutrition. Making sure that you regularly consume the standard recommended daily intake levels of the vitamins, mineral and other nutrients your body needs is the first vital step in keeping a healthy physic and mind.

But because of today's lifestyle and diet, it is very hard therefore to intake the proper daily amount of potassium necessary for a normal life. For this concern, nutritional supplements are the solution. They offer an efficient and reliable means of meeting not only our daily potassium needs but also other daily dietary requirements need by the system. Because the balance of nutrients is so important to achieving the optimum standards of performance and health, you may want to consider setting up a consultation with either a licensed nutritionist or your health care provider to create a personalized supplement plan; one that will be best suited to your individual dietary need and health goals.
