Structures of the Respiratory System

  • Nose- The nose includes the nasal cavity (space behind the nose), nasal septum(divides nasal cavity into R and L sides), Turbinates(bones that protrude into nasal cavity), Cilia (the hairs in the nose)
  • Sinuses- Are the cavities in the skull connected to nasal cavity.
  • Pharynx- Throat, passageway for air and food.
  • Epiglottis- Cartilage flap that prevents food from entering trachea.
  • Larynx-Voice box below Pharynx (vocal cords or glottis)
  • Trachea-windpipe 4 1/2 in long. have walls to keep it open.
  • Lungs- Cone shaped organs which fill the thoracic cavity (upper part =apex lower part =base).
  • Pleura-Thin,moist slippery membrane that covers lungs.
  • Mediastinum- Interpleural space, between the lungs.

Importance of the respiratory system/Relation to the immune system.

Importance of Respiratory system/Relation to immune system.

  • Importance-These include the nose, pharynx, larynx, trachea, bronchi and lungs. The respiratory system does two very important things: it brings oxygen into our bodies, which we need for our cells to live and function properly; and it helps us get rid of carbon dioxide, which is a waste product of cellular function.
  • Relation- The relation the immune system has with the respiratory system is the structures all play a very important role in helping the immune system function.

Relevance of nutrients to the respiratory system.

  • The respiratory system plays a vital role in homeostasis.
  • Vitamin D prevents respiratory disease in newborns.
  • Vitamin E prevents common colds.
  • Folate- Prevents respiratory infections.
