Q

What are the major lymphatic organs?

A

28
Q

The main blood supply of the brain in dogs is?

A

The internal carotid arteries

29
Q

The main blood supply of the brain in cats is?

A

Branches of the maxillary artery

30
Q

Which part of the intestine has a blood supply on both its mesenteric and antimesenteric borders?

A

Ileum

31
Q

The blood supply to the bladder is via what arteries?

A

internal pudendal and umbilical arteries

32
Q

Where is the heart located?

A

It is located obliquely in the middle mediastinum

33
Q

Where does the apex of the heart face?

A

It is ventrocaudal and more toward the left side

34
Q

Where does the base of the heart face?

A

It is dorsocranial and more towards the right side

35
Q

What covers the heart?

A

Pericardium

36
Q

What is the layer of inner pericardium that reflects on to the heart at the base and covers its exterior?

A

Visceral layer of the serous pericardium (epicardium)

37
Q

What happens during pericarditis?

A

There is a fluid increase in the pericardial cavity that could be due to infection or penetrating wounds from sharp objects from the stomach. It increases the intra-pericardiac pressure on the heart and decreases cardiac output

38
Q

Is the heart connected to the sternum?

A

NO!! At the apex of the heart a phrenico-pericardiac ligament that is formed of the pericardium connects to the sternum and the diaphragm

39
Q

How far does the mediastinum extend?

A

It extends from the thoracic inlet to the diaphragm.

40
Q

What contains the lungs?

A

The pleural sacs contain the lungs (not the pleural cavity

41
Q

What is hydrothorax?

A

It is excessive pleural fluid that is secreted by the serous membrane in the case of pleuritis. It occurs in the pleural cavity

42
Q

What is pneumothorax?

A

it is air due to to stab wounds at the cupulae pleura or lungs. It occurs in the pleural cavity

43
Q

Where does hemothorax occur?

A

It occurs in the mediastinum that normally extends into the pleural cavity due to punctured mediastinal pleura/e.

44
Q

What does the mediastinum contain?

A

It contains the heart, major blood vessels, lymph nodes, lymphatics, nerves, longus colli muscle, esophagus and trachea

45
Q

How is the position of the heart in the cat different from that of the dog?

A

the heart is more horizontal and can be auscultated from both sides

46
Q

Where are the borders of the heart in the dog?

A

It extends from the 3rd rib to the caudal border of the 6th rib (in some breeds 7th rib)

47
Q

Where can the heart be auscultated at in dogs?

A

between 3rd and 5th intercostal spaces

48
Q

What is the cardiac notch?

A

It is the area of the heart and the pericardium that is not covered by the lungs, it is present on the right side of the dog

49
Q

Where is the cardiac notch on the cat?

A

It is present on both the right and the left sides.

50
Q

Why is it a good thing that the ventral borders of the lobes of the lungs are thin in all species?

A

This makes this area useful for cardiac palpation and auscultation

51
Q

What is the auricular surface of the heart?

A

It is the part of the heart that faces the left thoracic wall (includes the left and right auricles, entire left atrium, and the greater part of the left ventricle and a part of the right ventricle on the left side)

52
Q

What is the atrial surface of the heart?

A

It is the part of the heart that faces the right thoracic wall and it contains the right atrium and the greater part of the right ventricle and a part of the left ventricle that is visible from the right side

53
Q

What is the purpose of the grooves on the heart?

A

They demarcate the relative boundaries of the chambers of the heart

54
Q

Does the paraconal interventricular groove reach the apex of the heart?

A

No

55
Q

What is the location of the subsinusoidal interventricular groove?

A

it is indistinct and lies below the large coronary sinus where the great cardiac vein opens that runs in the coronary groove on the right side.

56
Q

How many chambers does the heart consist of?

A

Four- two atria (receive blood), two ventricles (pump blood)

57
Q

What separates the atria internally? The ventricles?

A

The inter-atrial septum, the inter-ventricular septum

58
Q

What is they systole?

A

When the ventricles contract so the barometer shows a higher reading

59
Q

What is the diastole?

A

When the ventricles relax and the barometer shows a lower reading

60
Q

What demarcates the interventricular septum externally?

A

the paraconal interventricular groove on the left and the subsinusoidal interventricular groove on the right

61
Q

Where is the right atrium located?

A

dorsocranial to the right ventricle

62
Q

Where does the right atrium receive venous blood from?

A

The cranial and caudal vena cava, the heart itself via the coronary sinus, and the azygous vein

63
Q

Where does the great cardiac vein open?

A

below the opening of the caudal vena cava in the right atrium

64
Q

What is the main chamber of the atrium?

A

Sinus venarum cavarum

65
Q

On what side is the right auricle visible?

A

On the left
