changes in Earth’s orbit and tilt‚ volcanic activity‚ human activity. 2. How orbital changes may affect climate? Ans. When Earth’s orbit is elliptical‚ Earth encounters more variation in energy from the Sun. The tilt of the Earth’s axis also changes. When the tilt decreases‚ temperature differences between seasons decreases. Wobbling of Earth changes the direction of tilt and can reverse the seasons. 3. How changes in CO₂ concentrations affect global temperatures. Ans. Carbon dioxide is a greenhouse

Voyage to the Lungs Trevor Frederick HS 130 Unit #4 – Assignment Kaplan University February 26‚ 2013 Welcome aboard! So glad you are all able to witness this extraordinary endeavor into the amazing human body. What you are about to witness is a feat seldom seen by the average individual. Frantic reports coming in are alarming; a foreign bacterium has invaded the right lung of our subject and is currently causing some severe damage. Shrunken to a mere eight microns in length‚ our state-of-the-art

Determining lung capacity Experiment: This is the experiment of determining lung capacity. All the students in the group measured three types of different parameters: vital capacity‚ expiratory reserve and tidal volume. “Lung volumeizing refer to physical differences in lung volume‚ while lung capacities represent different combinations of lung volumes‚ usually in relation to inhalation and exhalation.The average pair of human lungs can hold about 6 liters of air‚ but only a small amount of
Premium Respiratory physiology Lung
How lungs Work Your lungs are part of a group of organs and tissues that all work together to help you breathe. This system is called the respiratory system. The main job of the respiratory system is to move fresh air into and get waste gases out of the body. Lungs are very important because Oxygen‚ a basic gas‚ is needed by every cell in your body in order to live. The air that comes into the body through the lungs contains oxygen and other gases. In the lungs‚ the

are hypertensive heart disease‚ coronary heart disease and heart failure. What is a respiratory disease? Respiratory disease is a class of diseases that involve every part of the lungs including the nerves and muscles of the lungs. Some of the respiratory diseases are pneumonia‚ pulmonary embolism‚ and lung cancer. Hypertensive heart disease Cause Hypertensive heart disease is caused by the arterial hypertension or high blood pressure that affects the heart. Symptoms

American Lung Association “The American Lung Association has been in existence for over 100 years. It is the America’s oldest volunteer health organization founded in 1904‚ as the National Association for the study and prevention of tuberculosis. It operates through a network of about 200 local offices across the United States as well as Puerto Rico and the U. S. Virgin Islands.” (www.answers.com). The American Lung Association’s goals are to eliminate tobacco use and tobacco-related lung disease

Lung Cancer Survival Guide Lung cancer is one of the deadliest forms of cancer in the world. The Cancer Research Center in England‚ a for-profit organization (whose goal is to improve the lives of cancer patients)‚ released a study done on lung cancer patients that have survived 1‚ 5‚ and 10 years after diagnosis. They found out that 33% of women and 29% of men survive lung cancer after one year of diagnosis. After five years 9.3% of women and 7.8% of men survive‚ after 10 years 5.9% of women and

How are they alike‚ and different? Is one more efficient than another? Gills/Lungs?HumansIn humans air travels into the mouth‚ or nose‚ and into the nasal cavity‚ followed by pharynx. The pharynx is where food and air cross paths. The pharynx increases the chance of choking‚ but also allows breathing when exercising and respiration though the mouth‚ if the nose is closed. Next‚ epiglottis opens allowing air to move into the glottis‚ and pass the larynx (voice box). After this air makes its way into

Lung cancer- Is the uncontrolled growth of abnormal cells that start off in one or both lungs. It usually starts in the cells that line the air passages. The abnormal cells do not develop into healthy lung tissue‚ they divide rapidly and form tumours.

-Malignant neoplasms of the lung: a) Primary lung tumors: Lung cancers are divided into two categories based on predominant cell type: - Non-small cell lung carcinomas (NSCLC): There are three common types of non small cell lung cancer. These are grouped together because they behave in a similar way and respond to treatment in a different way to small cell lung cancer.(58‚ 59) i) Adenocarcinoma: Now the most frequent primary lung cancer. It is usually the type of lung cancer found in non-smokers
