Heart (Mark) Flashcards
Describe circulation of the heart
Blood comes into the right atrium from the body, moves into the right ventricle and is pushed into the pulmonary arteries in the lungs.
- > After picking up oxygen
- > the blood travels back to the heart through the pulmonary veins into the left atrium
- > to the left ventricle and out to the body’s tissues through the aorta
Membranous part of interatrial septum
R - Aorta
G - Pulmonary trunk
Right fibrous trigone
What is anchoring pulmonary trunk to Right fibrous trigone
Ligament of Conus arteriosus
Name of this nerve.
-> Which artery travels with this nerve?
Phrenic nerve
-> travel with pericardiophrenic artery
Identify + name of chamber
Pectinate muscle at right atrium
Identify + what contributes to this?
Crista terminalis
(contributed by Septum spurium)
(The crista terminalis originates from regression of the septum spurium as the sinus venosus is incorporated into the right atrial wall )
R - SVC
G - Left brachiocephalic vein
R - Subclavian vein
G - Internal Jugular vein
Azygos vein (The last tributary of SVC(
Subclavian v. develop from __
Left 4th aortic arch (it also gives off aorta)
Recurrent laryngeal nerve (CN X)
What gives off the pulmonary trunk?
6th aortic arch
What does 3rd aortic arch gives off?
Proximal segment of internal carotid arteries on both sides
Descending aorta
Which vertebral level that the descending aorta gets attached and terminates?
T4
What kind of blood is found in this structure?
Pulmonary trunk
-> Deoxygenated blood (or venous blood)
What is this?
Pericardium
Which points determine the oblique sinus?
- Pulmonary veins + ivc
Name of the space (where the finger point)
Transverse sinus
Ligamentum arteriosum (connection between left pulmonary artery and descending aorta)
Which heart chamber is this?
Right atrium
Crista terminalis
