Functions Of The Digestive And Kidney Systems Of The Body
... This mobility starts to break up the hot-dog (chyme) in order to give it more surface area so that it can better mix with the acid and pepsinogen. Gastrin also relaxes the pyloric sphincter. Chyme is then passes into the small intestine for main absorption and digestion. The pH in the stomach returns to normal and the stretch receptor stop getting stimulated.

Alternate Energy Sources
... research facilities. The second way is for the plasma molecules to be heated up around temperatures of 5,000,000 C%. The kinetic energy is then extracted by passing through a magnetic field. This produces a strong voltage. The only disadvantages to this power source is the lack of knowledge we have for it. Hopefully, within time, we will learn about this new energy source so we can use it to power the future.
Fusion Power
Fusion Power is probably the biggest known Alternate Energy Resource. Fusion is the joining of the nuclei of two atoms to form the nucleus of a heavier element. It occurs mostly wit ...

... is autism. Autism, according to Hallahan and Kauffman (1997), is " a disorder characterized by extreme withdrawal, self-stimulation, cognitive deficits, language disorders, and onset before the age of thirty months." Although the cause of autism is not completely understood, it is known that it has something to do with a neurological or biochemical dysfunction. Contrary to what was originally thought, autism is not a form of mental retardation. It manifests itself in varying degrees of severity, from profound to mild. Dr. Temple Grandin is an assistant professor at Colorado State University who was diagnosed as aut ...

Diabetes
... from food. When we eat, the digestive process breaks down carbohydrates into glucose, which is absorbed into the blood in the small intestine.
People who don't have rely on insulin, a hormone made in the pancreas, to move glucose from the blood into the body's billions of cells. But people who have either don't produce insulin or can't efficiently use the insulin they produce. Without insulin, they can't move glucose into the cells. Glucose accumulates in the blood, a condition called hyperglycemia ("hyper" = too much, "glycemia" = glucose in the blood). Hyperglycemia causes intense thirst, the need to urinate fr ...

Medical Revolutions
... of medicine who served in the Civil War was, whether he liked it or not, first and foremost a surgeon and always referred to as such. Though his first knife may well have been government issued, he learned the tricks of the trade in due course and sometimes became quite an expert. “Do your best” was the general idea, and most surgeons did, or at least tried.
Nearly all the older doctors had received their education on an apprenticeship basis but the younger men, those who made up the bulk of the army surgeons, usually held a medical school diploma along with an office internship. Little attention was paid to c ...

Cadmium And Sewage Sludge
... present in air.
Most cadmium is obtained as a by-product from the smelting of zinc, lead or copper ores. Cadmium has a number of industrial applications, but it is used mostly in metal plating, pigments, batteries, and plastics.
Cadmium in the Environment
Small quantities of cadmium occur naturally in air, water, soil and food. For most people, food is the primary source of cadmium exposure, since food materials tend to take up and retain cadmium. For example, plants take up cadmium from soil; fish take up cadmium from water, and so on.
It is introduced into the environment from mining and smelting operations. O ...

The Ocean
... For the marine animals we have fish and shrimp. The fish and
shrimp are always moving around the ocean and follow the ocean currents.
What is ocean current? It is a movement of ocean thatcan buring the fish to
other places. There are two kinds of circulation create the currents in the
ocean. They are (1) wind-driven circulation and (2) Thermohaline circulation.
Wind-driven circulation result from the wind sets the surface waters into motion
as currents. The currents generally flow horizontally-that is parallel to the
earth¡¦s surface. The wind mainly affects only the upper 100 to 200 meters of
water. However, the ...

Astronomy And Space Science: Your Bones In Space
... It consists of specialized
connective tissue cells called osteocytes and a matrix consisting of
organic fibers held together by an organic cement which gives bone its
tenacity, elasticity and its resilience. It also has an inorganic
component located in the cement between the fibers consisting of calcium
phosphate [85%]; Calcium carbonate [10%] ; others [5%] which give it the
hardness and rigidity. Other than providing the rigid infrastructure, it
protects vital organs like the brain], serves as a complex lever system,
acts as a storage area for calcium which is vital for human metabolism,
houses the b ...

Mononucleosis
... at any age can get . Seventy to 80 percent of all documented cases, however, involve persons between the ages of 15 and 30. Both men and women are affected, but studies suggest that the disease occurs slightly more often in men than in women. Doctors estimate that each year 50 out of every 100,000 Americans have symptoms. Among college students, the rate is several times higher. does not occur in any particular "season," although authorities in colleges and schools, where the disease has been well studied, report that they see most patients in the fall and early spring. Epidemics do not occur, but doctors hav ...

Cloud Formations
... The different kinds of clouds are found in these three divisions according to the clouds' altitude.
First, we have the high clouds that range in altitude from 16,500 to 45,000 feet. In this division we have the cirrus, cirrocumulus, and cirrostratus clouds. A cirrus cloud appears in delicate, feather-like bands that are not attached to each other, and is usually white with no shading. Cirrocumulus clouds appear like very small round balls or flakes. The cirrocumulus clouds sometimes form a pattern of a buttermilk sky. The cirrostratus clouds sometimes form tangled webs or thin whitish sheets. A large ...
