Q

Aorta

A

The thickest artery in the body. Carries blood from the left ventricle to the rest of the body

17
Q

Brachiocephalic Branch

A

The first branch off of the aorta. Carries blood to the right caudal region.

18
Q

Carotid Branch

A

The second branch off of the aorta. Carries blood to the left side of the brain and face.

19
Q

Subclavian Branch

A

The third branch off of the aotra. Carries blood to the left axillary/brachial region.

20
Q

Superior Vena Cava

A

The large vein that collects blood from the superior aspect of the human body and dumps it into the right atrium.

21
Q

Inferior Vena Cava

A

The large vein that collects blood from the inferior aspect of the human body and dumps it into the right atrium.

22
Q

R. and L. Pulmonary Veins

A

Vessels that carry blood back from the lungs to the heart after the lungs oxygenated the blood. Dumps into the right atrium.

23
Q

R. Auricle

A

Fatty deposit of tissue on the right atrium

24
Q

L. Auricle

A

Fatty deposit of tissue on the left atrium

25
Q

Ligamentum Arteriosum

A

Ligament connecting the pulmonary arteries to the aortic arch

26
Q

Anterior Interventricular Sulcus

A

Depression between the right and left ventricle on the anterior side of the heart

27
Q

Posterior Interventricular Sulcus

A

Depression between the right and left ventricle on the posterior side of the heart

28
Q

Fossa Ovalis

A

A depression on the interior and medial side of the right atrium. Closed after birth but scarring remains.

29
Q

R. and L. Coronary Arteries

A

Runs from between the left and right atria around the heart. Left goes between left atrium and ventricle, right goes between right atrium and ventricle.

30
Q

R. Marginal Artery

A

Branch of RCA that runs on the right lateral side of the heart down the length of the right ventricle. Runs in the frontal plane.

31
Q

Posterior Interventricular Artery

A

Branch of the RCA that extends into the posterior sulcus between the ventricles

32
Q

L. Circumflex Artery

A

Branch of the LCA that wraps around the left atrium in the groove between the left atrium and ventricle.

33
Q

Anterior Interventricular Artery

A

Artery that is a branch of the LCA which runs in the groove between the right and left ventricle on the anterior side of the heart

34
Q

Coronary Sinus

A

Thick collecting duct on the posterior side of the heart between the left and right atrium. Flows into the right atrium.

35
Q

Great Cardiac Vein

A

Follows the circumflex branch of the LCA. Wraps around the left atrium in a clockwise fashion.

36
Q

Middle Cardiac Vein

A

Medium sized vein that runs between the left and right ventricle on the posterior side of the heart

37
Q

Small Cardiac Vein

A

Vein that runs counterclockwise around the border of the right atrium and ventricle from the coronary sinus.
