Nose, nasal cavity, paranasal sinuses, and larynx
Lower respiratory
Trachea, bronchial tree, and lungs
Nose
Entrance to the respiratory system
Nostrils/ Nares
The major point of entry for air entering the respiratory system
Nasal Cavity
Large, air filled space formed by ethmoid, maxilla, and nasal bones
Pharynx
Divided into nasopharynx, oropharynx, and laryngopharynx

Posterior to the nasal cavity and is lined with stratified squamous epithelia that secret mucus
adenoids
Two larger glandular structures found in the posterior region of the nasopharynx
oropharynx
Area of the throat at the back of the mouth

Trachea is usually known as
Bronchioles
Continually divide into terminal bronchioles which are the smallest branches of the bronchioles that lead into the alveoli

3 secondary bronchi, 3 lobes
Left primary
2 secondary bronchi, 2 lobes
The right side is bigger
Why is there 10 on the right and 8 on the left
Walls of respiratory bronchioles
Contain numerous sac-like alveoli where gas exchange occurs
The bronchioles and alveoli within the lungs
Transport oxygen from the air into the blood and remove carbon dioxide from the blood
Lungs
Paired organs that exchanges atmospheric gases with the blood
Lungs
Lie within the thoracic cavity which is surrounded by two layers of watery membrane called the pleura
CO2: Carbon dioxide and O2: Oxygen
What are atmospheric gases
Superior, middle, and inferior

Superior and inferior
What are the two lobes of the left lung
The cardiac notch
The heart is located within this region
Cardiac notch
Lower region of the left lung
In the capillaries of the uvuli
Where does gas exchange occur
Diaphram
Muscles between the the thorax and abdomen that is used for breathing

Diaphragm moves down when you
Exhale
Diaphragm moves up when you
