Elements in Animals and Humans Animals and humans have similar evolutionary backgrounds. Specific elements play critical roles in the structures of proteins and the activities of enzymes. The purpose of this page is to outline some of the uses of elements in the structure of animals and humans and to illustrate why these elements are essential in the body and for optimal health. * Calcium (Ca)
Structure of bone and teeth. * Phosphorous (Ph)
Structure of bone and teeth. Required for ATP, the energy carrier in animals. * Magnesium (Mg)
Important in bone structure. Deficiency results in tetany (muscle spasms) and can lead to a calcium deficiency. * Sodium (Na)
Major electrolyte of blood and extracellular fluid. Required for maintenance of pH and osmotic balance. * Potassium (K)
Major electrolyte of blood and intracellular fluid. Required for maintenance of pH and osmotic balance. * Chlorine (Cl)
Major electrolyte of blood and extracellular and intracellular fluid. Required for maintenance of pH and osmotic balance. * Sulfur (S)
Element of the essential amino acids methionine and cysteine. Contained in the vitamins thiamin and biotin. As part of glutathione it is required for detoxification. Poor growth due to reduced protein synthesis and lower glutathione levels potentially increasing oxidative or xenobiotic damage are consequences of low sulfur and methionine and/or cysteine intake. * Iron (Fe)
Contained in hemoglobin and myoglobin which are required for oxygen transport in the body. Part of the cytochrome p450 family of enzymes. Anemia is the primary consequence of iron deficiency. Excess iron levels can enlarge the liver, may provoke Diabetes and cardiac falurer. The genetic disease hemochromatosis results from excess iron absorption. Similar symptoms can be produced through excessive transfusions required for the treatment of other diseases. * Copper (Cu)
Contained in enzymes of the ferroxidase (ceruloplasmin?) system which regulates iron transport and facilitates release from storage. A structural element in the enzymes tyrosinase, cytochrome c oxidase, ascorbic acid oxidase, amine oxidases, and the antioxidant enzyme copper zinc superoxide dismutase. A copper deficiency can result in anemia from reduced ferroxidase function. Excess copper levels cause liver malfunction and are associated with genetic disorder Wilson's Disease * Manganese (Mn)
Major component of the mitochondrial antioxidant enzyme manganese superoxide dismutase. A manganese deficiency can lead to improper bone formation and reproductive disorders. An excess of manganese can lead to poor iron absorption. * Iodine (I)
Required for production of thyroxine which plays an important role in metabolic rate. Deficient or excessive iodine intake can cause goiter (an enlarged thyroid gland). * Zinc (Zn)
Important for reproductive function due to its use in FSH (follicle stimulating hormone) and LH (leutinizing hormone). Required for DNA binding of zinc finger proteins which regulate a variety of activities. A component of the enzymes alcohol dehydrogenase, lactic dehydrogenase carbonic anhydrase, ribonuclease, DNA Polymerase and the antioxidant copper zinc superoxide dismutase. An excess of zinc may cause anemia or reduced bone formation. * Selenium (Se)
Contained in the antioxidant enzyme glutathione peroxidase and heme oxidase. Deficiency results in oxidative membrane damage with different effects in different species. Human deficiency causes cardiomyopathy (heart damage) and is known as Keshan's disease. * Fluorine (Fl)
* Cobolt (Co)
Contained in vitamin B12. An excess may cause cardiac failure. * Molybdenum (Mo)
Contained in the enzyme xanthine oxidase. Required for the excretion of nitrogen in uric acid in birds. An excess can cause diarrhea and growth reduction. * Chromium (Cr)
A cofactor in the regulation of sugar levels. Chromium deficiency may cause hyperglycemia (elevated blood sugar) and glucosuria (glucose in the urine). Rats have been shown to have improved growth on diets which contain other micro nutrients. These include: * Lead (Pb)
* Nickel (Ni)
* Silicon (Si)
* Vanadium (Vn)
These elements are all toxic at high levels. SOURCE: http://www.csua.berkeley.edu/~wuhsi/elements.html

metals
Alkali metals such as sodium, potassium, and lithium are naturally present in the human body. These elements play important roles in various physiological processes, including nerve function, muscle contraction, and maintaining fluid balance.
The important alkaline earth metals in the human body are calcium and magnesium. Calcium is essential for bone and teeth formation, muscle function, and nerve transmission. Magnesium is involved in over 300 enzymatic reactions in the body, including energy production, muscle function, and DNA synthesis.
Sulfur does not occur in elemental form in the human body. Instead, sulfur is present in various compounds, which are primarily in solid or dissolved state.
Silicon is not considered an essential element for the human body. While trace amounts of silicon may be present in the body from dietary sources, it is not known to play a critical role in human physiology like other elements such as carbon, hydrogen, oxygen, and nitrogen.
Metals naturally present in the human body, such as iron, are in very small quantities and not magnetic enough to be attracted to magnets in the way iron or steel objects would be. Therefore, they do not typically exhibit magnetic properties strong enough to be visibly attracted by magnets.
Nonmetals make up most of the human body. The main elements found in the body are carbon, hydrogen, oxygen, and nitrogen, which are all nonmetals. Metals, such as calcium, iron, and potassium, are present in smaller amounts.
There are trillions of good bacteria present in the human body.

The smallest enzyme present in the human body is probably Triosephosphate isomerase.

Microorganisms present in the human body are typically very small, ranging in size from 0.2 to 10 micrometers.
Ventricles are present in the heart of the human body.
