carry on the habit. The more nicotine a smoker consumes‚ the more they will crave and so the more they will smoke. This means that they will be inhaling more toxic substances into their body‚ particularly the lungs‚ and this affects the breathing system as these substances will damage the lungs and cause a reduction in their ability to function properly. Carbon Monoxide One of the main functions of the respiratory system is to provide the body with oxygen so that it can be delivered to vital cells

Emphysema can be described as an abnormal condition of the lungs‚ with a noticeable decrease of respiratory function. It can also be associated with smoking or chronic bronchitis or old age. Cigarette smoke is the leading cause of emphysema. When inhaling tobacco smoke‚ it temporarily paralyzes the

disease that can affect this system is Lung Cancer‚ Bronchitis‚ Emphysema and Pneumonia. The disease that can affect the system as well is called Asthma. This disease is one of the common diseases I’ve known beside lung cancer. Asthma is a lung disease that inflames and narrows the airways. When the airways get inflamed‚ it causes the airways to become swollen and the muscles around it tighten. This makes it difficult for the air to move in and out of the lungs causing a continuously whistle sound

Using a spirometer to investigate human lung function The purpose of this activity is: • to show how a spirometer can be used to find the vital capacity of lungs and to calculate important subdivisions of this capacity. • to show how to interpret the trace resulting from use of a spirometer • to consider how to use a spirometer to estimate metabolic rate. Procedure SAFETY: Do not use a spirometer unless supervised by a teacher. If you are using the spirometer and you experience

Lung cancer is one of the top 3 cancer issues in the world. The number of lung cancer patients needs to be dropped because it’s very dangerous‚ it’s deadly‚ and it is still rising in deaths today. “Lung cancer was first described by doctors in the mid- 19th century.” In the early 20th century it was considered very rare‚ but by the end of the century it was the leading cause of cancer related deaths among men by more than 25 countries. In the 21st century‚ lung cancer became the leading cause of

of air that can be expelled from the lungs in one second during forced expiration. If the airway becomes smaller‚ then the resistance to airflow will increase and FEV 1 (%) will become lower. 8. FEV 1 (%) decreases as the radius of the airway is decreased. Airflow increases when surfactant is applied because the resistance to lung inflation has been reduced. 9. Surfactant is not produced in premature infants. Because surfactant is necessary for the lungs to inflate‚ it is not normally needed

American Lung Association says smoking affects around 9 million people in U.S alone‚ and it causes the death of approximately 450‚000 individuals per year. Cancer is a common serious threat of smoking. It also causes several aesthetic problems‚ cardiovascular problems‚ respiratory problems and reproductive health problems. This article discusses about various negative effects of smoking. 1. Respiratory Health Effects – Tobacco contains several toxic substances that damage our lungs and other

Plethysmography is used to measure changes in volume in different parts of the body. This can help check blood. The test may be done to check for blood clots in the arms and legs‚ or to measure how much air you can hold in your lungs. Lung plethysmography: You will breathe or pant against a mouthpiece. Clips will be put on your nose to shut off your nostrils. Depending on the information your doctor is looking for‚ the mouthpiece may be open at first‚ and then closed. You will be breathing
