Hydrogen sulfide (H2S) occurs naturally in crude petroleum, natural gas, volcanic gases, and hot springs. It can also result from bacterial breakdown of organic matter.
Hydrogen sulfide can also result from industrial activities, such as food processing, coke ovens, kraft paper mills, tanneries, and petroleum refineries.
The thyroid (THY-royd) gland is a small 2 inch long butterfly-shaped gland (two lobes) weighing less than an ounce, that is located in the front of your neck just below your Adam’s apple, beneath the voice box – or larynx.
The thyroid is one of a group of glands that are part of the endocrine system. The endocrine glands produce, store, and release hormones into the bloodstream that travel through the body and direct the activity of the body’s cells. Thyroid hormones regulate metabolism, which is the way the body uses energy, and affects nearly every organ in the body.
The liver is one of the largest organs on the “inside” of your body. Your skin is the largest organ on the “outide” of your body.
The liver has two parts, a right lobe and a smaller left lobe. The liver is found behind the lower ribs on the right side of the abdomen (AB-doh-men). Your abdomen is the area of the body that contains the pancreas, stomach, intestines, liver, gallbladder, and other organs.
The liver has MANY important functions that keep a person healthy:
Pronounced – AB-doh-men
The abdomen is the area between your chest and your hips in the front of your body.
The abdomen area contains the:
- Stomach – the organ in the upper part of the abdomen, under your ribs.
- Small intestine – the organ where most digestion occurs.
Pronounced – bak-teer-ee-um
Bacterium (plural bacteria) is a tiny, living, single-cell microorganism (microorganism requires a microscope to be seen) that reproduces by cell division and usually has a cell wall.
Bacterium can be shaped like a sphere, rod, or spiral, can be found in virtually any environment, and can be beneficial or cause infection and disease.
Vitamins, pronounced – vy-tuh-mins, and minerals are complex organic micronutrient substances, naturally found in minute (pronounced – mi-noot – meaning very tiny, small) quantities in some foods. Vitamins and minerals replace or fix low levels of important natural substances in your body that are essential to normal metabolism (the conversion of a chemical from one form to another). Some types of food have more of these substances than others. If you need extra vitamins and minerals, you may have to take vitamin pills that have them. Example:
- Vitamin D deficiency – (ricketts and osteomalacia) In children, the condition prevents normal bone development. In adults, a lack of vitamin D causes demineralization of bone, particularly in the spine, pelvis, and lower extremities.
- Vitamin D intoxication – A disorder marked by weight loss, nausea, vomiting, and impaired renal function.
Renal
Renal, pronounced – REE-nul, is relating to the kidneys. A renal disease is a disease of the kidneys. Renal failure means the kidneys have stopped working properly.
Pronounced – en-DOSS-koh-pee

The endoscope is moved through a body passageway or opening to see inside an organ. Sometimes endoscope are used for surgery.
An enzyme is almost always a protein.
Enzymes are needed for all bodily functions. Enzymes speed up chemical reactions in all parts of the body. An enzyme is not destroyed during the reaction and is used over and over.
There are thousands of different types of enzyme molecules, each specific to a particular chemical reaction. Enzymes are found in the stomach as gastric juice, in the mouth as saliva, in intestinal fluids, in blood, and in every other organ and cell in the body.
A fungus, pronounced – FUN-gus, is a small, often microscopic, single-celled or multicellular plant-like organism that does not make chlorophyll. Mushrooms, yeasts, molds, mildews, rusts, smuts, and puffballs are examples. The plural is fungi.
Y Chromosome is one of the two sex chromosomes, X and Y.
Sex chromosomes are the X or Y chromosome in human beings that determines the sex of an individual.
In humans, each cell normally contains 23 pairs of chromosomes, for a total of 46. Twenty two of these pairs, called autosomes, look the same in both males and females.
