Smoke

Tobacco Smoke and Lung Development This online experiment was mainly astir(predicate) how environmental tobacco heap, also known as second-hand commode, touch on infantile children under the age of quint. Researchers wanted to know how and if it does loan to lung problems. The meditation for this activity was that exposure to the cigarette smoke piece of music enceinte and after birth would result in changes in lung suppuration and development. In the experiment, mice were used in both the experimental and work groups. In the experimental group, pregnant female mice were indeterminate to the environmental tobacco smoke for one hour a day, volt geezerhood per week, until the birth of the pups. Once they are born, the pups were once again exposed to the cigarette smoke for one hour per day, five days per week for three weeks. In mold to break up the misemploy done to the lungs, we analyzed six slides of the lung tissue samples out of cxx slides. We measured the amount of septal tissue by estimating the septal tissue volume in separately slide practice a grid laid over the lung tissue image. We counted each instance that a grid crosshair touched septal tissue.

From the counts from the slides of the subordination group and the experimental group, we concluded that animals exposed to cigarette smoke have less septal tissue than the animals in the story group. The mice exposed to the ETS have less surface area in their lungs and most likely a reduced capability for swash exchange. In the end, we found out that the data we collected was self-consistent with the hypothesis that the second hand smo! ke did in power point affect lung development. In respect to humans, as the lungs continue to engender and develop, the size of the lung increases by the addition of new(a) septa. The harms of the ETS may run expedition the changes in lung structure by preventing the formation of new septa. As a result, the lungs will have fewer larger alveoli substance it would have lesser surface area easy for attack exchange.If you want to get a full essay, order it on our website: OrderCustomPaper.com
