Respiratory System essays

Respiratory System essays The bodys survival depends entirely on eleven systems. Right now lets discuss the respiratory system. This system is entirely important for survival of all tissues because without the respiratory system tissues will die and we all would be dead. Our body depends on the external environment, it is both as a source for survival and as a basin for its wastes. Our cells depend on oxygen to carry out its functions and the cells give off carbon dioxide, a waste product. Respiration involves four processes: pulmonary ventilation, external respiration, transport of respiratory gases, and internal respiration. The pathway is entirely complex but I wont be going into depth. The pathway starts from the nose and ends at the alveolus. The respiratory is also coupled with the circulatory system because without it oxygen and carbon dioxide, the bodys cells will begin to die from oxygen starvation. Starting from the nose the air will run till it ends at the alveolus, a small sac where oxygen and carbon dioxide is exchanged. The functions of the respiratory system are: pulmonary ventilation, external respiration, transport of respiratory gases, and internal respiration. The pulmonary system is the movement of air into and out of the lungs so that the gases are continuously exchanged commonly called breathing. Second, the external respiration is the movement of oxygen from the lungs to the blood and of carbon dioxide from the blood to the lungs. Third, transport of respiratory gases is the transport of oxygen from the lungs to the tissue cells of the body, and carbon dioxide from the tissue cells to the lungs. This uses the cardiovascular. Last, the internal respiration is the movement of oxygen from blood to the tissue cells and of carbon dioxide from tissue cells to blood. Breathing provides our head to be lightweight not heavy. The air enters hitting the nose and nasal cavity, pharynx, larynx, trachea, ...

Biography of Ruth Handler, Inventor of Barbie Dolls

Biography of Ruth Handler, Inventor of Barbie Dolls Ruth Handler (November 4, 1916–April 27, 2002) was an American inventor who created the iconic Barbie doll in 1959 (the doll was named after Handlers daughter Barbara). Barbie was introduced to the world at the American Toy Fair in New York City. The Ken doll was named after Handlers son and was introduced two years after Barbie debuted. Handler was the co-founder of Mattel, a company that manufactures a variety of popular toys. Fast Facts: Ruth Handler Known For: Handler founded the toy company Mattel and invented the Barbie doll.Born: November 4, 1916 in Denver, ColoradoParents: Jacob and Ida MoskoDied: April 27, 2002 in Los Angeles, CaliforniaSpouse: Elliot Handler (m. 1938-2002)Children: 2 Early Life Handler was born Ruth Marianna Mosko on November 4, 1916, in Denver, Colorado. Her parents were Jacob and Ida Mosko. She married Elliot Handler, her high school boyfriend, in 1938. Mattel With Harold Matt Matson, Elliot created a garage workshop in 1945. Their business name Mattel was a combination of the letters of their last and first names. Matson soon sold his share of the company, so the Handlers, Ruth and Elliot, took full control. Mattels first products were picture frames. However, Elliot eventually started making dollhouse furniture from picture frame scraps. That proved to be such a success that Mattel switched to making nothing but toys. Mattels first big-seller was the Uka-a-doodle, a toy ukulele. It was the first in  the line  of musical toys. In 1948, the Mattel Corporation was formally incorporated in California. In 1955, the company changed toy marketing forever  by acquiring the rights to produce the popular Mickey Mouse Club products. The cross-marketing promotion became common  practice  for future toy companies. In 1955, Mattel released  a  successful patented toy cap gun called the burp gun. Invention of Barbie In 1959, Ruth Handler created  the Barbie doll. Handler would later refer to herself as Barbies mom. Mattell founders Ruth and Elliott Handler with a barbie doll. Courtesy of Mattel   Handler watched her daughter Barbara and friends playing with paper dolls. The children used them to play make-believe, imagining roles as college students,  cheerleaders,  and adults with careers. Handler aspired  to invent a doll that would better facilitate the way young girls were playing with their dolls. Handler and Mattel introduced Barbie, the teenage fashion model, to skeptical toy buyers at the annual Toy Fair in New York on March 9, 1959. The new doll was very unlike the baby and toddler dolls that were popular at the time. This was a doll with an adult body. What was the inspiration? During a family trip to Switzerland, Handler saw the German-made Bild Lilli doll in a Swiss shop and bought one. The Bild Lilli doll was a collectors item  and  not intended for sale to children; however, Handler used it as the basis for her design for Barbie. The Barbie doll’s first boyfriend, the Ken Doll, debuted two years after Barbie in 1961. Handler said Barbie was a symbol of freedom and possibility for young girls and women: â€Å"Barbie has always represented that a woman has choices. Even in her early years, Barbie did not have to settle for only being Ken’s girlfriend or an inveterate shopper. She had the clothes, for example, to launch a career as a nurse, a stewardess, a nightclub singer. I believe the choices Barbie represents helped the doll catch on initially, not just with daughters- who would one day make up the first major wave of women in management and professionals- but also with mothers.† The Story of Barbie Handler created a personal story for the very first Barbie doll. She was named Barbie Millicent Roberts and she was from Willows, Wisconsin. Barbie was a teenage fashion model. Now, however, the doll has been made in many versions connected to over 125 different careers, including president of the United States. Barbie came as either a brunette or blond, and in 1961, a red-headed Barbie was released. In 1980, the first African-American Barbie and Hispanic Barbie were introduced. The first Barbie was sold for $3. Additional clothing based on the latest runway trends from Paris were sold as well for between $1 and $5. In 1959, the year Barbie was released, 300,000 Barbie dolls were sold. Today, a mint condition #1 Barbie doll can fetch as much as $27,000. To date, more than 70 fashion designers have made clothes for Mattel, using in excess of 105 million yards of fabric. There has been some controversy over Barbies figure ever since it was realized that if the doll were a real person, her measurements would be an impossible 36-18-38. Barbies real measurements are 5 inches (bust), 3 1/4 inches (waist), and 5 3/16 inches (hips). Her weight is 7  ¼ ounces, and her height is 11.5 inches. In 1965, Barbie had bendable legs and eyes that opened and shut. In 1967, a Twist N Turn Barbie was released that had a movable body that twisted at the waist. The best-selling Barbie doll of all time was the Totally Hair Barbie of 1992, which had hair from the top of her head to her toes. Other Inventions After fighting breast cancer and undergoing a mastectomy in 1970, Handler surveyed the market for a suitable prosthetic breast. Disappointed by the options available, she set about designing a replacement breast that was more similar to a natural one. In 1975, Handler received a patent for Nearly Me, a prosthesis made of material close in weight and density to that of natural breasts. Death Handler developed colon cancer in her 80s. She died on April 27, 2002, at the age of 85. Handler was survived by her husband, who died on July 21, 2011. Legacy Handler created one of the worlds most successful toy companies, Mattel. Her Barbie doll is one of the most popular and iconic toys in the world. In 2016, the Museum of Decorative Arts in Paris had a Barbie show featuring hundreds of dolls alongside artworks inspired by Barbie.
