Smoke

Tobacco Smoke and Lung Development This online experiment was mainly active how environmental tobacco heap, also known as second-hand grass, touch infantile children under the age of quint. Researchers wanted to know how and if it does r separately to lung problems. The meditation for this activity was that exposure to the cigarette smoke term enceinte and after birth would result in changes in lung suppuration and development. In the experiment, mice were used in both the observational and work groups. In the experimental group, pregnant female mice were opened to the environmental tobacco smoke for one hour a day, louvre geezerhood per week, until the birth of the pups. Once they are born, the pups were over again exposed to the cigarette smoke for one hour per day, five days per week for three weeks. In read to collapse the misemploy done to the lungs, we analyzed six slides of the lung tissue samples out of one hundred twenty slides. We measure d the amount of septal tissue by estimating the septal tissue volume in each slide engage 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 command group and the experimental group, we concluded that animals exposed to cigarette smoke have less septal tissue than the animals in the contestation 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 hypothe sis that the second hand smoke did in feat! ure affect lung development. In respect to humans, as the lungs continue to feed and develop, the size of the lung increases by the addition of refreshed septa. The harms of the ETS may hunt expedition the changes in lung structure by preventing the formation of new septa. As a result, the lungs will have fewer big alveoli substance it would have lesser surface area functional for attack exchange.If you want to get a full essay, order it on our website: OrderCustomPaper.com
