Smoke

Tobacco Smoke and Lung Development This online experiment was mainly roughly how environmental tobacco heap, also known as second-hand commode, impact infantile children under the age of quint. Researchers wanted to know how and if it does fall in to lung problems. The meditation for this activity was that exposure to the cigarette smoke time enceinte and after birth would result in changes in lung suppuration and development. In the experiment, mice were used in both the data-based and work groups. In the experimental group, pregnant female mice were unsolved to the environmental tobacco smoke for one hour a day, v 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 cast to snap the misemploy done to the lungs, we analyzed six slides of the lung tissue samples out of cxx slides. We measured the amount of septate t issue by estimating the septal tissue volume in each(prenominal) slide expend 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 supremacy group and the experimental group, we concluded that animals exposed to cigarette smoke have less septal tissue than the animals in the recital group. The mice exposed to the ETS have less surface area in their lungs and most likely a reduced capability for muff exchange. In the end, we found out that the data we collected was self-consistent with the hypothesis that the second hand smoke did in souvenir affect lung development. In respect to humans, as the lungs continue to recall and develop, the size of the lung increases by the addition of newborn 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 large alveoli substance it would have lesser surface area forthcomi! ng for attack exchange.If you want to get a full essay, order it on our website: OrderCustomPaper.com
