• Vocabulary development
•  
• 1-Gradient is the difference of measurement
  between two side or end.
• 2-Passive transport to transport an object
  without applying energy.
• 3-Semi-permeable not everything can pass
  through it, but is selective of the things that
  can pass through it.

• 4-Membrane acts as a barrier and controls and /
  or regulate what enters and leaves in a cell.
• 5-Diffusion is the ability to transport an
  object from an area of high concentration to an
  area of low concentration without applying
  energy.
• 6-Equilibrium When the situation equally
  balance and/or stable.

• Mechanism for Crossing the Membrane Barrier
• Passive Diffusion
• Simple diffusion is the movement of a substance
  from a place of high concentration to one of
  lower concentration without applying energy for
  this reason it is called passive transport.

• Analyze the diagrams and explain the direction or
  exchange of gas flow in the lungs of a human, by
  writing a paragraph or more with your partner(s).
  Attention should be noted that the oxygen gas
  (O2) is 90 and carbon dioxide gas (CO2) is 45
  in the alveolus of the lung. Also, the blood
  vessel called capillary contains 45 oxygen gas
  (O2) and 90 carbon dioxide gas (CO2) in the red
  blood cell.
• The flow of air in and out of the alveoli of the
  lung is called ventilation and has two stages
  inspiration (or inhalation) and expiration (or
  exhalation).
