Blunt impact to the thorax often results in traumatic rupture of the aorta, leading to immediate exsanguination. Current interest in the mechanisms of this failure is great (Roberts and Beckman, 1970), particularly with regard to vehicular fatilities in which passengers are subjected to high levels of deceleration
The lung constitutes a highly complex and selfregulating system for oxygenating man’s blood and removing its waste materials. It is at the alveolar level that the respiratory and circulatory functions interact and the important exchange processes occur
THE NUMBER of fatalities due to automobile collisions in the United States has reached an annual level of 55,000, according to the statistics of the National Safety Council. Of these, 16 per cent have been estimated by Greendyke (1966) to be due to traumatic rupture of the aorta, on the basis of a sample of 1253 automobile fatalities in Monroe County, N.Y., over a four year perio
The uptake of particulate matter by inhalation leads to complex transport processes influenced by unsteady convection through a non-dichotomously branching network of conducting conduits (airways)
