Lower Respiratory Tract Flashcards
delivers air to and from one of the lungs
five (5) lobes
Secondary Bronchi (Lobar Bronchi)
It contributes to the body’s defense against infections
Mucous Gland
It essential for the exchange of gasses and plays a role in immune
responses
Capillary Beds
It transport deoxygenated blood from the heart to the lungs
Pulmonary Artery
What structure has this function?
● formation and removal of parietal fluids
● lines the thoracic wall
● covers inside the thorax, mediastinum, and diaphragm
Parietal Pleura
It transport oxygenated blood from the lungs to the heart
Pulmonary Vein
Its function is to deliver air to a diffuse network
Terminal Bronchioles
The lower respiratory tract _____ oxygen,
_____ the oxygen into the blood, and
_____ of carbon dioxide
receive
transfer
release
The _____ are the passageways that connect your windpipe to your right and left lungs.
bronchi
The _____ helps moisturize the air you breathe and screen out foreign particles.
bronchi
The main functions of this structure are the ff:
● permits the lung to expand and contract
● prevent friction between parietal and
visceral pleura
● produce pleural liquids that act as
lubricants
Pleural
Membrane
It carries air to the left lung.
Left Main Bronchus
Its function is to conduct air in and out of a pulmonary lobule
Lobular Bronchioles
What structure has this function?
● protects the heart and lungs
● houses the organs and tissues in the chest
● provides a base for the muscle attachment
-Thoracic Wall
It receives and briefly hold blood returning from either the body (right
atrium) or the lungs (left atrium)
Atrium
It contributes to the effective exchange of oxygen and carbon dioxide
Alveolar Duct
It carries air to the right lung.
Right Main Bronchus
Its function is to deliver air to millions of alveolar clusters
Respiratory Bronchioles
What structure has this function?
● allow optimal expansion and contraction of
the lungs during breathing
Pleura Space
What are the five (5) lobes of the lungs?
- Right Upper Lobe (RUL)
- Right Middle Lobe (RML)
- Right Lower Lobe (RLL)
- Left Upper Lobe (LUL)
- Left Lower Lobe (LLL)
The bronchi _____ and _____ air to and from the lungs.
carry
distributes
It ensures that the body receives an adequate supply of oxygen
Alveolar Sacs
delivers air into compart mentalized sections of the lungs
Tertiary Bronchi (Segmental Bronchi)
It provides protection against external threats
Mucosal Lining
What structure has this function?
● covers the surface of the lungs
● allows easy movement of the lung and inflation during breathing
● continuous with parietal pleura
Visceral Pleura
It delivers air to a diffuse network. It also serves as a transition between the large cartilage
Bronchioles
aiding the processes of breathing
and respiration
Bronchioles
The functions of this structure are to pick up incoming energy (oxygen), release outgoing waste product (carbon dioxide), keep the body going
Alveoli
