Lou Gehrig
Lou Gehrig Lou Gehrig was born and raised in New York City, the son of German immigrant parents. His full name was Henry Louis Gehrig. After graduating from high school, he attended Columbia University where he became a football and baseball star. Lou's father directed him to becoming a pro baseball player. He became sick and needed on operation, but there was no money for doctors and hospital expenses in the family budget, so young Lou quickly capitalized on his baseball skills. He accepted an

Concepts of Lifetime Fitness September 1, 1997 Homeostasis is the state of equilibrium in which the internal environment of the human body remains relatively constant. Two excellent examples of homeostasis are how the body maintains a constant temperature and blood pressure during strenuous physical activity or exercise. Although there are many other activities in the body that display homeostasis, I will only discuss these two. Temperature in the human body is usually kept at approximately 37

From the beginning of mankind, man has looked for cures of illness. Jonas Salk found a cure for one of the worst illnesses in the history of man, polio. Jonas Salk's polio vaccine was a great discovery of his time, and it is still being used today to eradicate polio worldwide. Dr. Salk is also known for other medical discoveries. He was a quiet man who lived a rough childhood. He was not looking for fame, instead, it found him. During the time before the vaccine, many people, mostly parents wit

Scientists have currently discovered an estimated 2,500-3,000 living species of snakes living throughout the world except in the arctic regions. There is one exception to the old world viper, which has been found as far north as Scandinavia (60° North Latitude). The size variation of snakes ranges from slender b

THE EFFECTS OF ALTITUDE ON HUMAN PHYSIOLOGY Changes in altitude have a profound effect on the human body. The body attempts to maintain a state of homeostasis or balance to ensure the optimal operating environment for its complex chemical systems. Any change from this homeostasis is a change away from the optimal operating environment. The body attempts to correct this imbalance. One such imbalance is the effect of increasing altitude on the body's ability to provide adequate oxygen to be utiliz

Physiological Adaptations of the Plesiosaur for Holding its Breath
Physiological Adaptations of the Plesiosaur for ‘Holding its Breath’ One hundred and fifty million years ago, large aquatic species of reptile such as the Plesiosaur dominated the ocean, and were pre-eminent predators of the sea. The branch of now extinct Plesiosaurs, or ‘near lizards’, evolved into variant closely related species specialised to take different niches in the food chain. Such species of Plesiosaur include the phenotypically similar Plesiosauroid and Pliosauroid. The physiological

When coming across this project, I though it interesting to figure out what the difference in pulse rate was between athletes and non-athletes.

Anabolic Steroids
Anabolic Steroids
Anabolic Steroids The History of Steroids During the 1930’s scientists discovered that Anabolic Steroids could facilitate the growth of muscle (skeletal) in laboratory animals. This discovery paved the way for steroids to be introduced for human use. Throughout the following decade the trend of steroids became more pronounced, the first documented use of anabolic steroids dates back to World War 2; it is believed Hitler’s German soldiers were administered steroids to increase their confidence an

Some of reasons for this increase can be attributed to better training methods, better conditioning techniques, increased understanding of nutrition and better overall health of the athlete. Generally, these improvements involve one or more of the previously mentioned scenarios, but some athletes always seem to take it a step furthe

ANABOLIC STEROIDS Since ancient history, many athletes have resorted to performance enhancing aids to give them an edge on their opponents. Greek Olympians used strychnine and hallucinogenic mushrooms to psych up for an event. In 1886 a French cyclist was the first athlete to die from using a performance enhancer, called speedballs, a mixture of cocaine and heroin. In the 1920's, physicians inserted slices of monkey testicles into male athletes to help boost vitality. In the 1930's Aldof Hitler

Magnesium Magnesium is the twelfth element on the periodic table. It is located in the second group called the alkaline earth metals. Natural magnesium contains three different isotopes, and there are twelve others that are recognized. Seawater is a rich source of magnesium in the form of salt. Magnesium is the eighth most abundant element in the earth's crust. Magnesium readily ignites upon heating in air and burns with a dazzling white flame. To extinguish the flame water should not be used. A

Located in the thorax, it lies left of the body's midline, above and in contact with the diaphragm. It is situated immediately behind the breastbone, or sternum, and between the lungs, with its apex tilted to the body cavity's left side. In most people the apex can be felt during each heart contraction. At rest, the heart pumps about 59 cc (2 oz) of blood per beat and 5 l (5 qt) pe

Marfans Syndrome Marfan syndrome is a rare hereditary disorder of connective tissue, which causes connective tissue to be weaker than normal. Connective tissue is the most abundant tissue in the body. It supports and protects various other tissues, is a vital component of all organs in the body, and provides strength and elasticity to blood vessels. Therefore, a disorder of connective tissue can cause a variety of abnormal conditions. For people with the Marfan syndrome, weak connective tissue

Chemical warfare is the use of natural and man-made toxic substances to incapacitate or kill an enemy. There are many different types of agents used in chemical warfare, some of which are mustard gases, nerve gases, psychotomimetic agents, tear gases, hydrogen cyanide, and arsines. All of which are very poisonous and lethal when exposed to humans in large amounts. Until the 20th century such warfare was primarily limited to starting fires, poisoning wells, distributing smallpox-infected article

Muscle is the tough, elastic tissue that makes body parts move. All animals except the simplest kinds have some type of muscle. People use muscles to make various movements, such as walking, jumping, or throwing. Muscles also help in performing activities necessary for growth and for maintaining a strong, healthy body. For example, people use muscles in the jaw to chew food. Other muscles help move food through the stomach and intestines, and aid in digestion. Muscles in the heart and blood ves

Animals that hibernate shelter themselves from harsh winter and reduce their need for food. Their body temperatures are considerably lower, as well as their heartbeat and breathing. The true hibernator spends most of the winter in a state close to death; in fact the animal may appear to be dead. The body temperature is close to zero degrees; the respiration is

The Digestive System
The Digestive System
The Digestive System Digestion is the process by which food is converted into substances that can be absorbed by the intestine. Here is a short view of digestion. The process begins in the mouth, where the food is chewed and mixed with saliva, and continues with the action of digestive enzymes secreted by the stomach and pancreas. Rhythmic contractions of the muscular layer of the intestinal wall (called peristalsis) ensures a constant mixing of enzymes along the intestine. The products of dige

The Digestive System The digestive system is responsible for processing food, breaking it down into proteins, carbohydrates, minerals, fats, and other substances, and inject them into the bloodstream so that they can be used by the body. The digestive, or alimentary, tract begins at the mouth, where the teeth and tongue begin the breakdown of food, assisted by saliva from the salivary glands. Saliva contains enzymes which break up food and cause other chemicals to react easily with it. Two of t
