Q

in the intact body the front of the pericardial sac is attached to the back of the sternum by what

A

by mediastinal fat

22
Q

are ventricles mobile in the pericardial sacs

A

yes freely mobile

23
Q

what is the pericardium reflected on inferiorly and is it adherent

A

the diaphragm

yes densely adherent to it

24
Q

to the right and left the pericardium lies back to back with what

A

parietal pleura

25
Q

each of the great vessels pass through what as it enters or leaves the pericardial sac

A

through adherent cuff of pericardium

26
Q

the left pulmonary veins and left pulmonary artery pass through the pericardium together - true or false

A

false

they pass through separately

27
Q

the right pulmonary vessel are harder to see as they leave via what structure

what other structure does the right pulmonary vessel share the first structure mentioned above with

A

leave via a continuous cuff of pericardium that the share with the IVC

28
Q

within the thorax does the IVC have any length and when does it enter the right atrium

A

no length at all in thorax

enters the right atrium as soon as it passes through the diaphragm

29
Q

after the IVC comes up through the diaphragm it passes where in relation to the right atrium

A

almost immediately into the lower part of the right atrium

30
Q

the azygous vein arches over what structure before it joins which major vessel of the heart

A

over the right main bronchus

join SVC

31
Q

the azygous vein receives blood from what parts of the chest wall

A

posterior and lateral

32
Q

what veins empty into the azygous vein from the right side

A

the posterior intercostal veins

33
Q

what veins empty into the azygous vein from the left side

what part of the azygous vein does that vessel empty into

A

posterior intercostal veins

into hemi-azygous which then empties into the azygos

34
Q

on each side of the subclavian vein it joins which what vessel and where

A

joins with internal jugular vein

behind the medial end of clavicle

35
Q

what is formed by the subclavian vein joining the internal jugular vein

A

brachiocephalic vein

36
Q

what is the subclavian vein the principle vein of

A

the upper extremities

37
Q

what is the internal jugular vein the principle vein of

A

the head and neck

38
Q

the 2 brachiocephalic veins enter the thorax and joint to form what

A

the SVC

39
Q

the subclavian vein comes up from behind what muscle and passes where in relation to the clavicle

A

from beneath pectoralis minor

passes beneath the clavicle

40
Q

what muscle is in front of the jugular vein

A

omohyoid muscle

41
Q

the subclavian vein passes over what part of the first rib

A

the flat anterior part

42
Q

what muscles separates the subclavian vein from the subclavian artery

A

anterior scalene muscles

43
Q

what is beneath the subclavian vein

A

the dome of the pleura

44
Q

the internal jugular vein lies where in relation to the common carotid artery

A

lies in front of the CCA and lateral to it

45
Q

on each side what 2 vessels join to form the brachiocephalic veins

A

subclavian and internal jugular veins

46
Q

the 2 brachiocephalic veins pass down to what behind what structure to form what structure

A

pass down to the thorax behind the manubrium to join and form the SVC

47
Q

the SVC lies to the __ of the midline

what is a result of this regarding the right brachiocephalic vein compared to the left brachiocephalic vein

A

lies to the right of the midline

the right brachiocephalic vein is short and runs downwards while the left is longer and runs obliquely

48
Q

the SVC passes downwards and enters what structure

A

enters the pericardial sleeve

49
Q

to the SVC’s left is what and behind it is what

A

to its left is the ascending aorta

behind it is the trachea

50
Q

the SVC ends by doing what

A

entering the highest part of the hearts right atrium

51
Q

the azygous vein joins the vena cava from where just before the vena cava does what

A

from behind just before the vena cava enters the pericardium
