6 organs in the respiratory system
nose, pharynx, larynx, trachea, bronchi, lungs
what makes up the upper respiratory system
nose, pharynx, larynx
what makes up the lower respiratory system
trachea, bronchi, lungs
what is the function of the respiratory system
exchange of oxygen and carbon dioxide between the atmosphere and body cells
the process of exchanging oxygen and carbon dioxide between the atmosphere and body cells is called __?
respiration/breathing
external expiration
inhaling ..nose, pharynx, larynx, trachea, and bronchi to the lungs, allowing 02 and C02 to cross paths to pass from alveoli to blood and vice versa through capillaries
how does 02 pass from alveoli to blood stream
through capillaries
what is internal respiration
the body cells take on oxygen from the blood and simultaneously give back carbon dioxide
the pharynx, aka ____ serves as the ____
throat, food and air passageway
adenoids are what kind of tissue and located where? AKA____ function__
lymphoid tissue located on the posterior wall of the nasal cavity, AKA pharyngeal tonsils. help to fight off infection
tonsils are what kind of tissue and located where
lymphoid tissue located behind the mouth on the lateral wall at the junction of the oral cavity and the oropharynx
larynx , aka ____ is
voice box are vocal cords
epiglottis is
flap of cartilage that automatically covers the opening of the larynx during swallowing and kept food from entering the larynx
the trachea is
a passageway for air to the bronchi
bronchus, how many are there?
one of the two branches from the trachea which conducts air into the lungs where it divides
bronchioles
smallest subdivision of the bronchial tree
alveoli are___ their location & function___
air sacs at the end of the bronchioles that assist in 02 and C02 exchange through alveolar walls and capillaries
lungs are two ____ like organs in the ___ cavity
sponge, thoracic
which lung has two lobes and which has three
left has two and right has three
what is the pleura
double folded serous membrane covering each lung and lining the thoracic cavity
the thoracic cavity contains
heart, trachea, esophagus, aorta, pulmonary arteries and veins and lungs
