Functions of the respiratory system
Deliver air to lungs
Oxygen- blood- body cells
Airflow through larynx that makes speech possible
Respiratory system
Supplies the blood with oxygen for transportation to the cells in all of the body
Upper respiratory tract
Consists of the nose, mouth, pharynx, epiglottis, larynx and trachea
(Airway)
Lower respiratory tract
Consisted of bronchial tree and lungs
Located within and protected by the thoracic cavity (rib cage)
(Airway)
Nose
Air enters the body through the nose and passes through the nasal cavity
Nasal septum
Wall of cartilage that divides the nose into two chambers
Cilia
The thin hairs located just inside the nostrils. Filter Incoming air to remove debris
Mucous membranes
Line the nose
Mucus
Slippery secretion produced the the mucous membranes that protects and lubricates These tissues
Olfactory receptors
Nerve endings that acts as receptors for the SENSE OF SMELL
Paranasal sinuses
Air filled cavities lined with mucous membrane Located in the bones of the skull Para- near Nas- nose -al - pertaining to
Frontal sinuses
Frontal bone just above he eyebrow
Infection here can cause pain in that area
Sphenoid sinuses
In the sphenoid bone behind the eye and under the pituitary gland
Infection here can cause damage to vision
Maxillary sinuses
Largest of the paranasal sinuses
Located in the maxillary bones under the eye
Infection can cause pain the the posterior maxillary teeth
Ethmoid sinuses
Located in the ethmoid bones between the nose and the eyes
Pharynx
Throat
Receives air after it passes through the nose or mouth as well as food
Nasopharynx
First division
Posterior to the nasal cavity and continues downward to behind the mouth
Oropharynx
Second division
Portion that is visible when lookin into the mouth
Laryngopharynx
Third division
also shared by both the respiratory and digestive system
Larynx
Voice box
Located between the pharynx and the trachea
Contain vocal cords
Trachea
Windpipe
Transport air to and from lungs
Bronchi
Two large tubes
Bronchioles
Within the lung, each primary bronchus divides and subdivides into increasingly smaller bronchioles
Smallest branches of the bronchi
Alveoli
Air sacs
Very small grapple clusters doing at the end of the bronchioles
Pulmonary
Relating to or affecting the lungs
Lungs
Essential organs of respiration, are divided into loves
Right lung
Larger and has three lobes: upper, middle, and lower
Left lung
Two loves
Upper and lower
Mediastinum
The middle section of the chest cavity and is located between the lungs
Pleura
A thin, moist and slippery membrane that covers the outer surface of the lungs and lines the inner surface of the thoracic cavity
Parietal pleura
Outer layer of the pleura
Visceral pleura
Inner layer of pleura
Pleural cavity
Pleural space
Thin fluid filled space between the parietal and visceral pleural membranes
