To investigate the effect of gender on vital capacity and total lung capacity on human lungs.
To develop problem solving and experimental skills, for example, information is accurately processed and presented, experimental procedures are planned, designed and evaluated properly, producing valid results, recording results, and a valid conclusion is drawn.
To develop techniques of using a portable spirometer.
Can vital capacity and total lung capacity be measured by Spiropet?
How gender can affect the vital capacity and total lung capacity of human lungs?
The main objective of this experiment is to measure the vital capacity (VC) and total lung capacity (TLC) of people of different gender. The main methods used in this investigation can be divided into two parts, namely investigation on VC and investigation on TLC. The main method used for investigation of VC is by exhaling the maximum volume of air inhaled into the spirometer. The reading from the spirometer is then recorded. The main method for TLC is by inhaling the maximum volume of air, followed by normal exhalation. The remaining volume of air inside the lungs is forced into the spirometer. The reading of the spirometer is then multiplied by 6 to obtain TLC. The main results from this experiment is that the both the VC and TLC are higher in male students than females. Therefore, from this experiment, we can conclude that the VC and TLC of men are generally greater than women.

- Lung cancer is the uncontrolled growth of abnormal cells in one or both lungs. These abnormal cells do not carry out the functions of normal lung cells and do not develop into healthy lung tissue. As they grow, the abnormal cells can form tumors and interfere with the functioning of the lung, which provides oxygen to the body via the blood. Lung cancer is the number one cause of cancer deaths in the both men and women worldwide. Lung cancer has surpassed breast cancer as the most common cause of cancer related deaths in women....

- In this essay I am going to talk about the lungs and the stages of their embryonic development. I chose the lungs because they are one of the most important organs for survival -they supply oxygen to cells and release carbon dioxide to the atmosphere. This essay will mostly focus on the different stages of the lung development- the embryonic, the pseudoglandular, the canalicular, the terminal sac, and the postnatal stage. The successful maturation of the lungs requires the completion of both biochemical and physical processes.... [tags: lung, bronchioles ]

- Literature Review Lung cancer is the growth of abnormal cells in the lungs; it can either be in one or also in both. The growth of the lungs makes it easier for tumors to grow in them, which then causes cancer. Some symptoms that a person with lung cancer experiences is the following: coughing, pain in chest, shortness of breath, changes in voice, harsh sounds when breathing etc. There are different causes of lunch cancer in humans, the number one cause would be tobacco smoking, and other causes would be exposure to radon, secondhand smoke and air pollution (Zang, & Wynder, 1996)....

- Do you know what Lung Cancer is. Expanding your knowledge on Lung Cancer can save your life or the life of someone you may know. Learning about the demographics and statistics of lung cancer might make you realize that it is a serious issue that should be taken more into consideration. Here, you will get an understanding on how to prevent lung cancer from happening, and you will also learn how to treat lung cancer if diagnosed. Lung Cancer occurs when a person has abnormal cells that are uncontrollably growing in one or both lungs.... [tags: prevention, lung disease]

- 12,800 males and 10,700 females are diagnosed with lung cancer each year.(CancerCa)The lungs are vital organs in our body which are located in the chest. Lungs bring oxygen into our body and release carbon dioxide.( oncologychannelCom) The lungs are respiratory organs that are important because they take in fresh oxygen to your blood which is then carried to your cells. Cancer occurs when mitosis goes “wild”. This means that cell division keeps dividing uncontrollably. This happens because some of the genes in the cell have been damaged or lost....

- A ten year old girl, Sarah Murnaghan, has come across an issue that not many ten year olds will or should ever face. Sarah has cystic fibrosis, and her lungs have been destroyed due to the inherited chronic disease. The issue is whether Sarah should be able to receive an organ from just a child donor. Or adult donors, too. It is interesting to see which side a person would take when a child is involved. As a member of Delta Phi Epsilon, our philanthropy is cystic fibrosis and I know of many people and have heard many stories revolving this terrible disease.... [tags: Lung Transplant Policy ]

- Gross Anatomy of the Lungs An accurate and complete model of the branching pattern of the human bronchial tree remains elusive, though several different models have been described (Phillips et al, 1994). The most useful and widely accepted approach remains that of Weibel (Weibel, 1963; Weibel, 1991), who numbered successive generations of air passages from the trachea (generation 0) down to alveolar sacs (generation 23). This “regular dichotomy” model assumes that each bronchus regularly divides into two approximately equal-size daughter bronchi; it is unlikely to be tru in practice where bronchus length is variable, pairs of daughter bronchi are often uneq...

- Cancer of the lung was nearly nonexistent in the early 1900’s. By the middle of the 20th century an epidemic became apparent throughout the United States and the rest of the world. It is primarily correlated with the widespread abundance of cigarette smoking in the world. The tobacco industry has multiplied its production immediately prior to World War I. There was a typical 20 to 30 year lagging period between the initiation of cigarette smoking and the actual tumor formation in the lungs. Lung cancer is the cancer that originates in the tissues of the lungs.... [tags: Health]

- Lung transplantation has been an effective measure for patients suffering critical respiratory illnesses, however this procedure is not without the necessity of long-term monitoring and use of immunosuppressive drug regimens to prevent acute and chronic rejection. To allow lung transplantation become more effective, immunosuppressive drug regimens must be compared to assess which regimen will provide maximal patient survival with minimal immunosuppression. Historically, cyclosporine (Cyc) in combination with azathioprine (Aza) and prednisone were often used to prevent acute and chronic rejection among patients2, but high morbidity and mortality rates have attracted testing of other immunosup...

- The Respiratory System and Looking at the Lungs Just as a fire needs oxygen to burn, the human body also needs a continuous supply of this essential element for the process of combustion that goes on constantly in every cell. We ordinarily do not think of a body metabolism as combustion, yet that is what is: the controlled burning of carbohydrates, fats, and proteins to provide energy. The job of the respiratory system is to furnish the oxygen that combines with these fuels in each of the billions of cells, and to carry away the waste product of carbon dioxide.... [tags: Papers]
