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.
