-esophageal opening T10
-aortic opening T12
Caval opening ( inferior vena cava)
T8 vertebral lvl
What is the Caval openings passage for?
Inferior vena cava
Phrenic nerve
Phrenic nerve
C3, C4, C5
Esophageal opening
T10 vertebral lvl
Esophageal opening passage for: what nerves

left gastric artery
Esophageal tributaries branches into what vein?
left gastric vein
Aortic opening
T-12 Vertebral lvl
Aorta opening is a passage for
-Aorta
-Azygos vein
-Thoracic lymphatic duct
The respiratory membrane is lined by ?
Mucous membrane
Mucous membranes lines all body cavities exposed to …
exterior
[resp. , digestive, urinary, reproductive]
What cells secrete mucous?
-Goblet
What does the parietal pleura cover?
covers walls of pleural cavity
-costal part
-diaphragmatic part
-mediastinal part
-cervical pleura
Visceral pleura covers?
surface of the lung
What is the Pleura cavity
space btw visceral and parietal layers (serous fluid)
Cervical pleura covers?
covers apex of lung (froms cup dome over apex)
Costodiaphragmatic recess is ?
where costal and diaphragmatic pleura meet ( where diaphragm/ lung serous fluids meet)
Costomediastinal Recess is ?
pleural space where costal pleura meets mediastinal pleura meet.
Pneumothorax is ?
entry of AIR into pleural cavity
Hydrothorax is ?
FLUID into pleural cavity
Hemothorax is?
BLOOD into pleural cavity
Thoracentesis is performed at ?
9th intercostal space
What is the blood flow to the lung and root structure
R. Atrium–> R .Ventricle
–>Pulmonary Trunk–> R/L Pulmonary Arteries–> Lobar/segmental arteries–> capillaries—>segmental veins R/L —Pulmonary Veins–> LAtrium–>LV- aorta
The Right Lung consists of:
-3 lobes
(superior, inferior, middle)
-2 fissures
(horizontal and oblique)
Right Lung Mediastinal Surface adjacent to:
-heart, inferior vena cava, superior vena cava, azygos v., esophagus
Left Lung Mediastinal Surface adjacent to:
-heart, aortic arch, thoracic aorta
-Cardiac impression
-Lingula
Bronchial Tree : TRACHEA
-C7 to T4/5
-bifurcates at sternal angle
Role of Lobar Bronchi
-supplies a lobe of the lung
Segmental Bronchi
-supplies broncho pulmonary segments w/ pulmonary artery branch aid
Bronchioles and Terminal Bronchioles
-direct air
What are the airway conducting zones?
Trachea, main bronchi, lobar and segmental bronchi, bronchioles and terminal bronchioles
What are the air way respiratory zones?
Respir. Bronchioles, alveolar ducts, alveolar sacs
Lung Lobule consists of:
-resp. bronchioles
-alveolar ducts
-alveolar sacs
-alveoli
- what are resp. bronchioles
gas transportation/exchange
alveolar ducts
-elongated airways
-alveolar sacs
clusters of alveoli
-alveoli
forms respiratory membrane
Where does Bronchial A originate and what does it do?
-originate from thoracic aorta
-supply blood w/ nutrition
Where does the Bronchial v. Drain to
right bronchial v. drains to azygos v.
Left bronchial v drains to accessory hemi-zygos
Pulmonary plexus consists of:
-symapthetics
-parasympathetics
-symapthetics
form postsynaptic fibers from paravertebral ganglia
Right vagus nerve is …
behind root of lung
left vagus nerve is … to lung
in front of root of lung
Visceral efferents supplies?
Supplies the muscle
Visceral afferents supplies?
ascending neurons / reflexes that help control function such as coughing
Nociceptive where it allows for painful stimuli such as ischemia
Parasympathetic neurons provides ?
MOTOR INN. to smooth muscle airway
Bronchoconstrictor: reduce airway
Vasodilator: increase blood flow
Sympathetics
MOTOR INN. to smooth muscle airway
Bronchodilator: increase airway
Vasoconstrictor: reduce blood away
