A

Most posterior

2
Q

Where is the trachea located compared to the esophagus?

A

Anterior to it

3
Q

Where does the right pulmonary artery pass?

A

Underneath the aortic arch

4
Q

Where does the left pulmonary artery pass?

A

Anterior to descending thoracic aorta

5
Q

Where is the SVC compared to the ascending aorta?

A

To the right of it

6
Q

Where is the pulmonary trunk located?

A

Anterior to the aorta

- then it switches

7
Q

Where are the great vessel located?

A

Above the heart

8
Q

Where does the main pulmonary trunk arise from?

A

The right ventricle

9
Q

What does the main pulmonary trunk bifurcate into?

A

Left and right pulmonary arteries

10
Q

What kind of blood do the pulmonary arteries carry?

A

Deoxygenated blood

11
Q

What do pulmonary veins do?

A

Drain the oxygenated blood from the lungs into the left atrium

12
Q

What are the 3 main branches off of the aorta arch?

A
  1. Brachiocephalic
  2. Left common carotid artery
  3. Left subclavian artery
13
Q

What makes up the brachiocephalic veins? (2)

A
  1. Subclavian veins

2. Internal jugular veins

14
Q

What makes up the SVC? (2)

A
  1. Left brachiocephalic vein

2. Right brachiocephalic vein

15
Q

Where does the SVC empty into?

A

The superior aspect of the right atrium

16
Q

Where does the IVC empty into?

A

The inferior aspect of the right atrium

17
Q

What is a 2 chamber view?

A

Long axis view

- sagittal

18
Q

What does the long axis view demonstrate?

A

The left ventricle and left atrium

19
Q

Where is the apex situated?

A

In the left ventricle

20
Q

What chamber view shows the valves really well? (2)

A
  1. 2 chamber view

2. 4 chamber view

21
Q

What is a 4 chamber view?

A

Coronal view

22
Q

What does the 4 chamber view demonstrate?

A

The four chambers of the heart

23
Q

What does a 5 chamber view demonstrate?

A

The four chambers of the heart with the aortic root/ascending aorta leaving the ventricle

24
Q

What can you see really well with the 5 chamber view?

A

The root of the aorta

25
Q

What does the 3 vessel view demonstrate?

A
The great vessels leaving/entering the heart
- SVC
- aorta 
- main pulmonary artery 
ductus arteriosus (fetus)
26
Q

What are the 3 vessels in the vessel view?

A
  1. SVC
  2. Aorta
  3. Pulmonary artery
27
Q

What happens in the ductus arteriosus?

A

The blood from mom goes into the pulmonary artery

- goes away in adults (only present in fetus’s)

28
Q

What is the view of the short axis (owl view)?

A

Transverse

- axial

29
Q

What does the short axis demonstrate? (2)

A
  1. The wall of the left and right ventricles

2. Papillary muscles

30
Q

How does the left ventricle look from a short axis view?

A

Circular

- thick walls

31
Q

How does the right ventricle look from a short axis view?

A

Half of a moon

- semilunar/crescent shaped

32
Q

Are pulmonary arteries or veins lower?

A

Pulmonary veins

33
Q

Why cant you see the trachea when you are at the level of the lungs?

A

Because it has already bifurcated
