Q

WHAT DO BRONCHIAL ARTERIES SUPPLY? WHY ARE THEY NECESSARY?

A

BRONCHIAL ARTERIES SUPPLY STRUCTURES COMPRISING THE ROOT OF THE LUNG AND SUPPORTING TISSUES. THEY ARE NECESSARY, BECAUSE THE PULMONARY ARTERIES PROVIDE POORLY OXYGENATED BLOOD.

Q

(BLANK) VAGUS CONTRIBUTES TO THE (BLANK) ESOPHAGEAL PLEXUS.

A

LEFT, ANTERIOR; RIGHT, POSTERIOR

18
Q

WHAT ELSE CONTRIBUTES TO THE ESOPHAGEAL PLEXUS?

A

SYMPATHETICS FROM THORACIC SPLANCHNICS

19
Q

FUN FACT: THE RIGHT BRONCHIAL ARTERY BRANCHES OFF OF A PARIETAL BRANCH OF THE AORTA! BUT, IT’S CONSIDERED VISCERAL.

A

YEP!

20
Q

THREE THINGS THAT THE AZYGOS DRAINS?

A

BRONCHIAL VEINS
ESOPHAGUS
INTERCOSTAL VEINS

21
Q

HOW DOES THE AZYGOS COMMUNICATE WITH THE ABDOMINAL CAVITY?

A

THROUGH A DIRECT CONNECTION TO THE ASCENDING LUMBAR VEINS

22
Q

HOW DOES THE AZYGOS COMMUNICATE WITH THE PORTAL SYSTEM? WHAT DISEASE SHOULD BE KEPT IN MIND CONCERNING THIS?

A

THROUGH AN INDIRECT CONNECTION TO THE ESOPHAGEAL VENOUS PLEXUS; PORTAL HYPERTENSION

23
Q

WHERE DOES THE THORACIC DUCT BEGIN? WHERE DOES IT DRAIN INTO?

A

BEGINS INFERIOR TO THE DIAPHRAGM

EMPTIES AT JUNCTION OF LEFT SUBCLAVIAN VEIN AND LEFT JUGULAR VEIN

PERICARDIAL SAC
ROOTS OF GREAT VESSELS: ASCENDING AORTA, PULMONARY TRUNK, SVC

27
Q

TWO PARTS OF PERICARDIAL SAC SUPPLIED BY PHRENIC NERVE

A

FIBROUS AND PARIETAL LAYER OF SEROUS PERICARDIUM

28
Q

BLOOD VESSELS ON THE PERICARDIAL SAC SUPPLY WHICH LAYERS OF THE SAC?

A

PARIETAL AND VISCERAL LAYERS OF THE VISCERAL (SEROUS) PERICARDIUM

29
Q

LIGAMENTUM ARTERIOSUM, LEFT RECURRENT LARYNGEAL, AND ARCH OF THE AORTA ARE ALL AT ABOUT WHAT VERTEBRAL LEVEL?

A

Q

WHICH ATRIUM HAS THE CRISTA TERMINALIS?

A

RIGHT SIDE!

33
Q

WHAT’S THE CONUS ARTERIOSUS? WHAT IS ITS EQUIVALENT ON THE OPPOSITE SIDE?

A

SMOOTH AREA IN THE RIGHT VENTRICLE THAT LEADS TO THE PULMONARY TRUNK; AORTIC VESTIBULE IN LEFT VENTRICLE

34
Q

WHICH VENTRICLE IS THICKER?

A

LEFT

35

IN THE AORTIC VALVE, HOLES ON EACH SIDE ARE CALLED (BLANK)

A

OSTEA OF CORONARY ARTERIES

37
Q

NERVES TO THE HEART ARE PRE OR POST GANGLIONIC?

A

POST, BECAUSE IT IS ABOVE THE DIAPHRAGM

38
Q

EFFERENT NERVES TO THE HEART COME FROM THREE SOURCES

A
  1. VAGUS
  2. OFF OF THE CHAIN AT T1-4
  3. FROM CERVICAL CHAIN GANGLION
