INTRASEGMENTAL
THE MIDDLE LOBAR BRONCHUS COMES OFF OF THE ____________
RIGHT INFERIOR LOBAR BRONCHUS
LEFT VAGUS NERVE GIVES OFF TWO IMPORTANT THINGS ON ITS WAY TO THE ESOPHAGUS.
- CERVICAL CARDIAC VAGAL BRANCHES
2. THORACIC CARDIAC VAGAL BRANCHES
SOME NERVES CONTRIBUTING TO THE ESOPHAGEAL PLEXUS COME STRAIGHT OFF OF THE CERVICAL CHAIN GANGLION.
CERVICAL SYMPATHETIC CARDIAC BRANCHES
THORACIC SYMPATHETIC CARDIAC BRANCHES
HOW MANY BRONCHIAL ARTERIES ARE THERE ON THE RIGHT? ON THE LEFT?
1 ON THE RIGHT; 2 ON THE LEFT
WHAT DO BRONCHIAL ARTERIES SUPPLY? WHY ARE THEY NECESSARY?
BRONCHIAL ARTERIES SUPPLY STRUCTURES COMPRISING THE ROOT OF THE LUNG AND SUPPORTING TISSUES. THEY ARE NECESSARY, BECAUSE THE PULMONARY ARTERIES PROVIDE POORLY OXYGENATED BLOOD.

ESOPHAGEAL ARTERIES
ONE PARIETAL BRANCH COMING OFF OF THE AORTA

FUN FACT: THE RIGHT BRONCHIAL ARTERY BRANCHES OFF OF A PARIETAL BRANCH OF THE AORTA! BUT, IT’S CONSIDERED VISCERAL.
YEP!
THREE THINGS THAT THE AZYGOS DRAINS?
BRONCHIAL VEINS
ESOPHAGUS
INTERCOSTAL VEINS
HOW DOES THE AZYGOS COMMUNICATE WITH THE ABDOMINAL CAVITY?
THROUGH A DIRECT CONNECTION TO THE ASCENDING LUMBAR VEINS
HOW DOES THE AZYGOS COMMUNICATE WITH THE PORTAL SYSTEM? WHAT DISEASE SHOULD BE KEPT IN MIND CONCERNING THIS?

WHERE DOES THE THORACIC DUCT BEGIN? WHERE DOES IT DRAIN INTO?
BEGINS INFERIOR TO THE DIAPHRAGM
