RESPIRATORY SYSTEM - LUNGS - GASEOUS EXCHANGE - ASTHMA

• The lungs are the organs responsible for gas exchange.
• Gas exchange occurs between alveoli (tiny air sacs) and capillaries (small blood vessels).
• Alveolar walls have thin membranes that allow gases to diffuse easily.
• Upper Respiratory Tract includes nose, pharynx (throat), larynx (voice box) and trachea (windpipe).
• Lower Respiratory Tract consists of bronchi, bronchioles, alveoli and pleurae.
• Capillary walls also have thin membranes, allowing gases to pass through them quickly.
• Capillary walls also have thin membranes, allowing gases to pass through them quickly.

• Capillary walls also have thin membranes, allowing gases to pass through them quickly.
• In the case of oxygen diffusion into the body, there is a higher concentration of oxygen outside the body than inside it.
• Diffusion is the movement of molecules from an area of high concentration to an area of low concentration until equilibrium is reached.
• Diffusion is the movement of molecules from an area of high concentration to an area of low concentration until equilibrium is reached.
• Diffusion is the movement of molecules from an area of high concentration to an area of low concentration until equilibrium is reached.
• Diffusion is the movement of molecules from an area of high concentration to an area of low concentration until equilibrium is reached.
• Lower Respiratory Tract includes bronchi (bronchus singular), bronchioles, alveoli (air sacs)

• Diffusion is the movement of molecules from an area of high concentration to an area of low concentration until equilibrium is reached.
• Airways are lined with mucous membrane which produces sticky mucus to trap dust particles.
• Bronchioles are smaller tubes branching off from bronchi.
• Bronchioles are smaller tubes branching off from bronchi.
• Bronchioles are smaller tubes branching off from bronchi.

• Diffusion is the movement of molecules from an area of high concentration to an area of low concentration until equilibrium is reached.
• Airways are lined with mucous membrane which produces sticky mucus to trap dust particles.
• Bronchial tree is made up of branching tubes called bronchi, which lead into smaller tubes called bronchioles.
• Bronchial tree is made up of branching tubes called bronchi, which lead into smaller tubes called bronchioles.
• Bronchial tubes branch into smaller and smaller tubes called bronchioles until they reach tiny air sacs called alveoli.

• Bronchial tree is made up of branching tubes called bronchi, which lead into smaller tubes called bronchioles.
• The respiratory system is responsible for the exchange of oxygen and carbon dioxide between the body's cells and the external environment.
• The respiratory system is responsible for breathing and gas exchange with the environment.
• Airways end at tiny air sacs called alveoli where oxygen enters the bloodstream through diffusion.
