Q

What is parietal pericardium?

A

It is made up of two layers; a serous layer and a fibrous layer

17
Q

What is the outermost layer covering the heart?

A

Mediastinal pleura

18
Q

What is the coronary groove?

A

Depression which contains the coronary vessels; line that separates the atria and ventricles; circles heart

19
Q

What does the right atrium receive?

A

It receives blood from systemic veins and coronary veins

20
Q

Where is the right atrium located in the dog? (231-32)

A

On the right side; cranially

21
Q

Where is the right auricle located in the dog? (229-30)

A

On the right side; cranial to the atrium

22
Q

Where are the pectinate muscles located?

A

In the auricles

23
Q

Where does the vena cava (2 parts) enter the heart? (229-30)

A

Enters the right atrium (caudal and cranial)

24
Q

Where is the coronary sinus? (232)

A

Enters the right atrium just ventral to the caudal vena cava

25
Q

What is endocardium?

A

Endothelial lining of the inside of the heart

26
Q

What are the artioventricular valves? (234)

A

Valves between the atria and ventricles; R = tricuspid, L = bicuspid

27
Q

What are cordae tendineae? (234)

A

Fibers which attach to artioventricular valve flaps

28
Q

What are papillary muscles? (234)

A

Attachment points for cordae tendineae on atrioventricular valves

29
Q

What is the pulmonary trunk?

A

Large blood vessel which emerge from the right ventricle carries blood to the lungs; divides into L&R pulmonary arteries

30
Q

What does the left atrium receive?

A

Blood from the pulmonary veins

31
Q

Where is the left ventricle located in the dog? (231-32)

A

On the left side; extends down to the apex

32
Q

How is the wall of the left ventricle different from the right? (231-32)

A

It is thicker

33
Q

Where are the semilunar valves located?

A

In the aorta and the pulmonary trunk

34
Q

How is the semilunar valve in the aorta different from the one in the pulmonary trunk?

A

The one in the aorta has thicker cusps

35
Q

Where is the left coronary artery located? (231)

A

Travels around the left ventricle (3 branches)

36
Q

Where is the right coronary artery located? 232)

A

Travels caudally on the right side between the atrium and the ventricle

37
Q

What is the great cardiac vein? (231)

A

Vein begins on the left side at the apex and empties blood into the right atrium through the coronary sinus
