The thinner walled ventricle on the inferior portion of the heart. Located inferior to the superior vena cava and right atrium.

Question 2

R. Atrium

Answer 2

The chamber directly attached to the superior and inferior vena cava

Question 3

L. Ventricle

Answer 3

The thicker walled ventricle that pumps blood out the aorta.

Question 4

L. Atrium

Answer 4

The chamber that receives blood from the pulmonary veins and pumps blood into the left ventricle

Question 5

Pulmonary Valve

Answer 5

The valve that prevents back flow from the the pulmonary arteries back into the right ventricle

Tricuspid Valve

Answer 7

Prevents back flow from the Right ventricle to the Right atrium.

Question 8

R. Atrioventricular Valve

Answer 8

Prevents back flow from the right ventricle to the right atrium.

Question 9

Bicuspid Valve

Answer 9

Prevents back flow from the left ventricle to the left atrium.

Question 10

Mitral Valve

Answer 10

Prevents back flow from the left ventricle to the left atrium.

Question 11

L. Atrioventricular Valve

Answer 11

Prevents back flow from the left ventricle to the left atrium.

Question 12

Papillary Muscles

Answer 12

Pull on the chordeae tendinae to open/shut the atrioventricular valves

Question 13

Chordae Tendineae

Answer 13

The chords connecting the AV valves to the papillary muscles

Question 14

Pulmonary Trunk

Answer 14

The junction of the pulmonary arteries leaving the right ventricle

Question 15

Pulmonary Arteries

Answer 15

The arteries that carry blood to the lungs from the right ventricle. Flow superior to the left atrium and inferior to the aortic arch.

Question 16

Aorta

Answer 16

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

Question 17

Brachiocephalic Branch

Answer 17

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

Question 18

Carotid Branch

Answer 18

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

Question 19

Subclavian Branch

Answer 19

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

Question 20

Superior Vena Cava

Answer 20

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

Question 21

Inferior Vena Cava

Answer 21

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

Question 22

R. and L. Pulmonary Veins

Answer 22

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

Question 23

R. Auricle

Answer 23

Fatty deposit of tissue on the right atrium

Question 24

L. Auricle

Answer 24

Fatty deposit of tissue on the left atrium

Question 25

Ligamentum Arteriosum

Answer 25

Ligament connecting the pulmonary arteries to the aortic arch

Question 26

Anterior Interventricular Sulcus

Answer 26

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

Question 27

Posterior Interventricular Sulcus

Answer 27

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

Question 28

Fossa Ovalis

Answer 28

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

Question 29

R. and L. Coronary Arteries

Answer 29

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.

Question 30

R. Marginal Artery

Answer 30

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.

Question 31

Posterior Interventricular Artery

Answer 31

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

Question 32

L. Circumflex Artery

Answer 32

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

Question 33

Anterior Interventricular Artery

Answer 33

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

Question 34

Coronary Sinus

Answer 34

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

Question 35

Great Cardiac Vein

Answer 35

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

Question 36

Middle Cardiac Vein

Answer 36

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

Question 37

Small Cardiac Vein

Answer 37

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