C&b D&p V1 Chp3 Coronary Arteries/veins

Front 1

Arterial blood supply to the heart comes from the root of the aorta by the means of _ coronary arteries.

Back 1

Front 2

What are the aortic sinuses? How are they related to the coronary arteries?

Back 2

The sinus is the part behind the aortic valve. In the *right*and *left* aortic sinuses, there are two holes - these are where the corresponding *right* and *left* coronary arteries arise from

Front 3

Where do the two coronary arteries arise from?

Back 3

The aortic left and right aortic sinuses.

Front 4

What is the 'coronary sulcus'?

Back 4

A groove in the heart that both coronary arteries follow

Front 5

What is the infundibulum?

Back 5

The entrance from the right ventricle into the pulmonary artery and pulmonary trunk

Branch of the right coronary artery which supplies the right ventricular wall

The posterior interventricular artery is a branch off the...it travels along the _______________ groove on the _____________ surface of the heart, towards its apex

Back 9

Branch off the right coronary artery. It travels along the atrioventricular groove on the *diaphragmatic* surface of the heart

Front 10

Largest branch off the right coronary artery. It travels along the atrioventricular groove on the diaphragmatic surface of the heart

Back 10

The posterior interventricular artery

Front 11

What structures does the right coronary artery supply?

Back 11

The RA
Most of RV
AVN and AV bundle

Front 12

The right coronary artery supplies the strip adjoining the interventricular groove on the front of the heart T/F

Back 12

F

Front 13

This branch of the right coronary artery supplies a small strip on the left ventricle. It also supplies the posterior part of the interventricular septum

Back 13

The posterior interventricular branch.

Front 14

Which artery supplies the posterior part of the interventricular septum?

Back 14

The posterior interventricular artery

Back 16

Posterior interventricular branch

Front 17

Both coronary arteries supply the SA bundle T/F

Back 17

F, both supply the AV bundle

Front 18

The left coronary artery arises from which sinus?

Back 18

The left sinus, it squeezes through the left auricular appendage and the infundibulum to reach the coronary sulcus

Front 19

Once the left coronary artery reaches the coronary sulcus, it divides into two terminal branches. What are these called?

Back 19

A large *anterior interventricular artery* and the *circumflex artery*

Front 20

A large *anterior interventricular artery* and the *circumflex artery* are the two branches of which coronary artery?

Back 20

The left coronary artery

Front 21

This artery travels towards the apex in the anterior interventricular groove. At the apex its terminal branches anastomose with those of the posterior interventricular artery.

Back 21

The anterior interventricular artery

Front 22

This artery travels in the coronary sulcus and anastomoses with terminal branches of the right coronary artery.

Back 22

The circumflex artery

Front 23

The left coronary artery supplies:

Back 23

The left atrium and left ventricle (except for small strip on the left ventricle on the diaphragmatic surface)
The anterior interventricular branch supplies the strip of the right ventricle adjacent to it and the anterior part of the interventricular septum. In the septum it anastomoses with branches of the posterior interventricular artery.

Front 24

This artery supplies the strip of the right ventricle adjacent to it and the anterior part of the interventricular septum.

It anastomoses in the septum with branches of the posterior interventricular artery

Back 24

The anterior interventricular branch of the left coronary artery

Front 25

The coronary arteries anastomose, so why is it an issue if one is blocked?

Back 25

The branches are often not large enough to form a collateral circulation quickly enough following sudden occlusion of one coronary artery

Front 26

Eventually, all cardiac veins drain towards the...on the anterior/posterior surface on the heart

Back 26

Coronary sulcus on the posterior surface of the heart

Front 27

This vein follows the anterior interventricular groove and then the left part of the coronary sulcus

Back 27

The great cardiac vein

Front 28

This vein receives venous blood from the atrial and ventricular tributaries

Back 28

The great cardiac vein

Front 29

This vein travels along the posterior interventricular groove and arrives at the coronary sulcus on the back of the heart

Back 29

The middle cardiac vein

Front 30

This vein runs with the marginal artery as far as the coronary sulcus and then proceeds to the back of the heart

Back 30

The small cardiac vein

Front 31

What is the name for the cardiac veins that drain directly into the right atrium?

Back 31

The 'anterior cardiac veins'

Front 32

All three large veins (great, middle and small) drain into the...

Back 32
