  • Preventing Adverse Health Effects from Nanotechnology From smartphones to skincare, there are currently over 1000 commercial products containing nanomaterials, with applications as far ranging as the fields of medicine, engineering, electronics and energy production. This session of Public Health Grand Rounds focuses on the current state of knowledge in nanotechnology and discusses concerns about the harmful impact that exposure to some nanomaterials may have on humans and the environment.

  • Breathing Movements Check us out at Breathing consists of two phases, inspiration and expiration. During inspiration, the diaphragm and the intercostal muscles contract. The diaphragm moves downwards increasing the volume of the thoracic (chest) cavity, and the intercostal muscles pull the ribs up expanding the rib cage and further increasing this volume. This increase of volume lowers the air pressure in the alveoli to below atmospheric pressure. Because air always flows from a region of high pressure to a region of lower pressure, it rushes in through the respiratory tract and into the alveoli. This is called negative pressure breathing, changing the pressure inside thelunsg relative to the pressure of the outside atmosphere. In contrast to inspiration, during expiration the diaphragm and intercostal muscles relax. This returns the thoracic cavity to it's original volume, increasing the air pressure in the lungs, and forcing the air out
  • How the Body Works : Breathing Breathing The body's breathing apparatus is enclosed in an expansile bony cage, formed by the ribs, the spinal column and the sternum. The floor of the cage is closed by the muscular diaphragm. Air passes down the windpipe, or trachea, to enter the lungs. During inspiration, or inhaling, the diaphragm moves downward and becomes flatter, and the rib cage expands. This creates a partial vacuum in the lungs and, to equalize the pressure, air is drawn in. Expiration, or exhaling, is passive. The lungs have elastic tissue in their walls and during inspiration this is stretched. In expiration its natural recoil causes the lungs to partially deflate.
