Lesson 9 (Part 4) Flashcards
Where is the esophagus located?
Most posterior
Where is the trachea located compared to the esophagus?
Anterior to it
Where does the right pulmonary artery pass?
Underneath the aortic arch
Where does the left pulmonary artery pass?
Anterior to descending thoracic aorta
Where is the SVC compared to the ascending aorta?
To the right of it
Where is the pulmonary trunk located?
Anterior to the aorta
- then it switches
Where are the great vessel located?
Above the heart
Where does the main pulmonary trunk arise from?
The right ventricle
What does the main pulmonary trunk bifurcate into?
Left and right pulmonary arteries
What kind of blood do the pulmonary arteries carry?
Deoxygenated blood
What do pulmonary veins do?
Drain the oxygenated blood from the lungs into the left atrium
What are the 3 main branches off of the aorta arch?
- Brachiocephalic
- Left common carotid artery
- Left subclavian artery
What makes up the brachiocephalic veins? (2)
- Subclavian veins
2. Internal jugular veins
What makes up the SVC? (2)
- Left brachiocephalic vein
2. Right brachiocephalic vein
Where does the SVC empty into?
The superior aspect of the right atrium
Where does the IVC empty into?
The inferior aspect of the right atrium
What is a 2 chamber view?
Long axis view
- sagittal
What does the long axis view demonstrate?
The left ventricle and left atrium
Where is the apex situated?
In the left ventricle
What chamber view shows the valves really well? (2)
- 2 chamber view
2. 4 chamber view
What is a 4 chamber view?
Coronal view
What does the 4 chamber view demonstrate?
The four chambers of the heart
What does a 5 chamber view demonstrate?
The four chambers of the heart with the aortic root/ascending aorta leaving the ventricle
What can you see really well with the 5 chamber view?
The root of the aorta
What does the 3 vessel view demonstrate?
The great vessels leaving/entering the heart - SVC - aorta - main pulmonary artery ductus arteriosus (fetus)
What are the 3 vessels in the vessel view?
- SVC
- Aorta
- Pulmonary artery
What happens in the ductus arteriosus?
The blood from mom goes into the pulmonary artery
- goes away in adults (only present in fetus’s)
What is the view of the short axis (owl view)?
Transverse
- axial
What does the short axis demonstrate? (2)
- The wall of the left and right ventricles
2. Papillary muscles
How does the left ventricle look from a short axis view?
Circular
- thick walls
How does the right ventricle look from a short axis view?
Half of a moon
- semilunar/crescent shaped
Are pulmonary arteries or veins lower?
Pulmonary veins
Why cant you see the trachea when you are at the level of the lungs?
Because it has already bifurcated
