30
Q

What is significant about the jejunum blood supply?

A

Rectus, muscles over ileum and anal region

36
Q

A

The kidneys

40
Q

What does the ovarian/testicular veins drain?

A

Genitals

41
Q

Where do the ovarian/testicular veins lie?

A

Ovarian - broad ligament

Testicular - peritoneal fold

42
Q

How many blood supplies does the liver have? Name them.

A

2

  • Hepatic artery, branch of the celiac artey
  • Portal vein
43
Q

Why is anastomoses important?

A

Tissue is not compromised as there is more than one route for blood circulation.So if one route is jepordised there is a backup.

44
Q

What branches merge to form the portal vein?

A

Cr. mesenteric vein
Cd. mesenteric vein
Splenic vein
Gastroduodenal vein

45
Q

What is the mammae blood supply equation

A

5 pairs
2 thoracic
2 abdominal
1 inguinal

46
Q

What are the cr/cd mammae arteries?

A 
Lateral thoracic artery
Intercostal arteries
Cr. superficial epigastric artery
Phrenicoabdominal artery
Cd. superficial epigastric artery
Deep circumflex artery
47
Q

What supplies the thoracic mammae?

A

Lateral thoracic and intercostal arteries

48
Q

What supplies the cd. thoracis and cr. abdominal mammae?

A

Cr. superficial epigastric artey

49
Q

What supplies the abdominal mammae?

A

Phrenicoabdominal artery

50
Q

What supplies the abdominal and inguinal mammae?

A

Cd. superficial epigastric artery

51
Q

What supplies the caudal abdominal and inguinal mammae?

53
Q

What does the uterine artery supply?

A

Body and horn of uterus

54
Q

Where does the uterine artery arise from?

A

The vaginal artery of which is from the internal pudendal, which is from the internal iliac

55
Q

Where does the uterine branch of the ovarian artery lie?

A

Caudally in broad ligamnet

56
Q

Where does the uterine artery lie?

A

57
Q

What does the uterine artery anastomose with?

A

Uterine branch of ovarian artery - cranially

Vaginal artery - caudally

58
Q

What is the pathway for ovarian drainage?

A

Ovarian vein -> caudal vena cava -> left renal

59
Q

What is the pathway for uterine drainage?

A

Uterine vein -> internal iliac -> caudal vena cava eventually

60
Q

Are veins satellite to arteries for mammae, ovary and uterus supply?

A

Yes
