21
Q

Visceral/Pulmonary Pleura

A

Lining over the surface of the lungs

22
Q

Parietal Pericardium

A

Thin, removable layer encasing the heart; fibrous (attached to pericardial-medistinal parietal pleura) & serous layers (shiny, inner)

23
Q

Visceral Pericardium or Epicardium

A

Layer directly attached to the outer surface of the heart; tightly attached

24
Q

Endocardium

A

Inner lining of heart

25
Q

Phrenicopericardial Ligament

A

Continuation of fibrous pericardial pleura to sternum & diaphragm

26
Q

Mediastinum

A

Theoretical space that contains the middle organs of the thoracic cavity; cranial, caudal and middle divisions

27
Q

What 4 structures are continuous through all three divisions of the mediastinum?

A

Esophagus
Vagus n.
Thoracic duct
Aorta

28
Q

Name the lobes of the LEFT lung; what impressions are found here?

A

Cranial lobe (w/ cranial & caudal divisions)
Caudal Lobe
Impressions: Aortic (mostly caudal), costal

29
Q

Name the lobes of the RIGHT lung; what impressions are found here?

A 
Cranial lobe
Middle lobe
Caudal lobe

30
Q

What 4 structures make up the carotid sheath?

A

Tracheal duct

31
Q

What structures can be seen on the root of the lung?

A

Pulmonary a. (BLUE) - branching off Pulmonary Trunk
Pulmonary v. (RED)
Lobar bronchi - trachea bifurcates into principal bronchi (R&L) and then lobar which go to each lobe of the lungs
Bronchial a. (RED) - small & alot

32
Q

Carina

A

Midline cartilagenous ridge on the inside of the trachea as it bifuracates into principal bronchi

33
Q

What lymph nodes are found at the “V” of the tracheal bifurcation?

A

Tracheobrochial lymph nodes

34
Q

Blood flow of the heart

A

Cranial/caudal vena cava > R Atrium > R A-V Valve > R Ventricle > Pulmonary Valve > Pulm trunk > L/R Pulm Artery > L/R Lung > L/R Pulm veins > L atrium > L A-V Valve > L Ventricle > Aortic Valve > Ascending Aorta > Coronary A > Aortic Arch

35
