• Factors Inflencing Ventilation

  The lowered surface tension reduces the tendency of alveoli to collapse completely. Therefore, if there is no surfactant, the surface tension in the lungs is much greater. As a result, the alveoli collapse greater at the end of each exhalation.

• Why pulmonary and systemic circulatory systems are separated

  This is reflected in the fact that the wall of the left ventricle is much thicker than the wall of the right ventricle.

• Organs of the respiratory passageways and how Boyle's Law relates to inspiration and expiration.

  Namely, we are talking about the lungs. The human body has two lungs and they are made up, that the smallest level, of tiny sacs called alveoli.

• Medical Terms and Definition - Emphysema

  They are the site of gas exchange. Oxygen (that we breathe in) diffuses into the blood in the alveoli. Likewise, carbon dioxide that the cells produce as waste diffuses out of the blood and into the alveoli (so that we can breathe it out).

• Partial pressures, gas exchange and respiratory measurments.

  The blood is oxygenated in the alveoli, and the gradient causes CO2 to diffuse out and O2 to diffuse in. By the time the blood is through the alveoli it is at the same partial pressure as the blood in the alveoli. It goes to the organs.

• Pulmonary Pathophysiology

  Perfusion has to do with the capacity for blood coming to the alveoli to exchange gases with the air that has made it to the alveoli.

• Cardiovascular function and the effects of smoking

  He is also diagnosed with early signs of emphysema, a non-reversible affect of smoking on the alveoli. Alveoli, to me, look like little bunches of grapes. Emphysema is when the walls of alveoli are broken down.

• Endocrine

  Exchange of gases occurs across the epithelium of the (10)______.

• Intrathoracic Pressure

  The differences between the pressure in the pleural cavity and that within the lung alveoli is determined.
