The Respiratory System
A Breath of Fresh Air
Upper Structures
The structures of your upper respiratory system are :
- Nose
- Sinuses
- Pharynx
- Epiglottis
- Larynx
- Trachea
The Nose
- Nasal Cavity (space behind the nose)
- Nasal Septum (divides nasal cavities into R and L sides)
- Turbinates (increases space , bones that protrude into nasal cavity)
- Cilia (the hairs in your nose , traps larger dirt particales)
The Sinuses
- Cavities in the skull, duct connects them o the nasal cavity, lined with mucous membrane to warm and moisten the air
- Frontal (forehead)
- Maxillary (cheek bones)
- Ethmoid
- Sphenoid
- Gives voice resonance
The Pharynx
- Throat
- Passageway for air and food, about 5 inches long
- Nasopharynx (above and behind soft palate, Eustachian tubes open in this)
- Oropharyxn (oral part of the mouth)
- Laryngopharynx
- Epiglottis (cartilage flap, prevents food from entering tranchea
Continuous Upper Structure
- Larynx - Voice box is the triangular chamber below pharynx
- Vocal cords or Glottis
- Sound is formed by vibration
- Adam's Apple
- Trachea - cough releases dust-laden mucous
Lower Structures
The Lower Respiratory System
- Lungs - contains bronchial tubes, bronchioles, bronchi and aveoli
- Pleura - most slippery membrane , doubled-wall sac
- Pleura cavity is space where the lungs sit
- Mediastinum - interpleural space and contains thymus , aorta , pulmonary artery and veins , esophagus , trachea and thoracic duct
Relationship with Immune System
- The respiratory system is continuously at risk for infection or damage from external agents.
- Foreign antigens - they provide sites where lymphocytes are sensitized to mount immune responses.
Nutrients
- The respiratory system helps you breath in things you need
- Oxygen
- When you eat foods
