Q

This is the posterior branch that supplies blood to the vertebral column

A

Vertebral artery

24
Q

This large unpaired artery is derived just posterior to the union of the systemic arches

A

Coeliaco-mesenteric artery

25
Q

This is the anterior branch which gives off smaller vessels such as the left and right gastric artery, hepatic artery and pancreatic artery

A

Coeliac artery

26
Q

This branch off into duodenal artery, intestinal artery, splenic artery and haemorrhoidal artery

A

Anterior mesenteric artery

27
Q

These are small blood vessels that supply the dorsal surface of the kidneys

A

Renal arteries

28
Q

This delivers blood to the large intestine. This unpaired artery specifically supplied the posterior region of the rectum

A

Posterior mesenteric artery

29
Q

These deliver blood to the oviduct

A

Oviducal arteries

30
Q

These supply blood to the testes and ovaries respectively

A

Spermatic and ovarian artery

31
Q

This supplies blood to the corpora adiposa

A

Adiposal artery

32
Q

This originates from the ventral wall of the common iliac artery

A

Epigastrico-vesical artery

33
Q

This delivers blood to the ventral abdominal wall

A

Epigastric artery

34
Q

This delivers blood to rectum and urinary bladder

A

Recto-vesical artery

35
Q

It branches posterior to the epigastrico- vesicular artery. This extends dorsally supplying the skin and muscles of the anterior part of the thigh

A

Femoral artery

36
Q

It is continuous with common iliac artery and is the major vessel entering the hindlimb

A

Sciatic artery

37
Q

This is the posterior branch of the truncus arteriosus

A

Pulmocutaneous artery

38
Q

This delivers deoxygenated blood to the lungs

A

Pulmonary artery

39
Q

This supplies the skin on the dorsal and lateral body walls. It branches off an auricular artery that supplies the jaw muscles, hyoid muscles and tissues of the lower jaw

A

Cutaneous artery

40
Q

This system concentrates on the organization of the veins and all that branch off from it

A

Venous system

41
Q

It is the most anterior branch draining into the precava. It is formed by the union of lingual and mandibular veins

A

External jugular veins

42
Q

Drains blood from the tongue, hyoid and floor of the mouth

A

Lingual vein

43
Q

Drains blood from the lower jaw and thyroid gland

A

Mandibular/Maxillary vein

44
Q

This is the middle branch of the vein, which is formed by the union of the internal jugular vein, and subscapular vein

A

Innominate vein

45
Q

Accepts many veins draining the palate, brain, orbital, nasal and auditory regions

A

Internal jugular vein

46
Q

Collects blood coming from the shoulder and forelimbs

A

Subscapular vein

47
Q

This is the posterior branch of the precava

A

Subclavian vein

48
Q

Collects blood from the forelimb

A

Brachial vein

49
Q

Formed by the union of muscular vein from the dorsal and lateral regions of the body wall and by cutaneous vein from the skin of the body wall

A

Musculo-cutaneous vein

50
Q

This comes near the posterior of the kidney as a result of the fusion of a large renal vein. This vein is also the route of the blood that has been collected from certain organs through the capillaries before it returns to the heart

A

Postcaval vein

51
Q

It consists of hepatic portal vein and its tributaries: gastric vein, pancreatic vein, splenic vein and intestinal vein

A

Hepatic portal system

52
Q

It consists of a large, renal portal vein which is formed by the femoral vein, sciatic vein, dorso-lumbar veins and oviducal vein

A

Renal portal system

53
Q

These vessels collect blood exclusively of red blood cells, which seeps through the walls of the capillaries and return it to the veins

A

Lymphatic system

54
Q

A series of contractile vesicles where the lymph is pumped throughout the system

A

Lymph hearts

55
Q

Receives blood from the left atrium. This then bifurcates to become the truncus arteriosus

A

Conus arteriosus

56
Q

A triangular thin-walled sac which accepts blood from the three caval veins

A

Sinus venosus
