part 2 – blood vessels
Examine the diagrams and perform the dissection of the cat blood vessels. Be able to
define and identify (where possible) the following.
SYSTEMIC VEINS
Cranial Vena Cava – drains cranial to diaphragm
Azygos vein – drains chest wall
R & L intercostal veins – drains thoracic wall
R & L brachiocephalic vein
R & L external jugular vein – drains head and neck
R & L internal jugular vein – drains brain
R & L superficial cervical vein – drains neck and shoulder
R & L cephalic vein – drains superficial forelimb
transverse jugular vein – joins R & L external jugulars
R & L subclavian vein
R & L axillary vein – drains shoulder
R & L brachial vein – drains brachium
R & L radial vein – drains antebrachium and paw
R & L ulnar vein – drains antebrachium and paw
Caudal Vena Cava – drains caudal to diaphragm
R & L hepatic vein – drains liver
Hepatic Portal System (veincapillariesvein)
Hepatic portal vein (drains most digestive organs into the liver)
Cranial mesenteric vein – drains intestines, pancreas
Gastrosplenic vein – drains spleen, stomach
R & L renal vein – drains kidneys
R & L ovarian or testicular vein – drains gonads
R & L common iliac vein
Caudal vein (right side) – drains tail
R & L internal iliac vein – drains pelvic organs
R & L external iliac vein – drains hind limb
R & L femoral vein – drains hindquarter
R & L medial saphenous vein – drains medial limb
R & L popliteal vein – drains deep and lateral limb
R & L lateral saphenous vein – drains lateral limb
Coronary Sinus – drains heart muscle
SYSTEMIC ARTERIES
Ascending Aorta
R & L coronary arteries – supplies heart
Aortic Arch
Brachiocephalic artery – supplies right forelimb and head
R&L common carotid artery – supplies head and neck
L internal carotid artery – supplies brain
L external carotid artery – supplies head
R subclavian artery
R axillary artery – supplies shoulder
R brachial artery – supplies forelimb
R radial artery – supplies antebrachium and paw
R ulnar artery – supplies antebrachium and paw
L subclavian artery – same branches as R
Descending Aorta
Thoracic Aorta
R & L intercostal arteries – supply thoracic wall
Abdominal Aorta
Celiac artery (trunk)
Hepatic artery – supplies liver
L gastric artery – supplies stomach
Splenic artery – supplies spleen, pancreas, stomach
Cranial mesenteric artery – supplies intestines
R & L renal artery – supply kidneys
R & L ovarian or testicular artery – supplies gonads
Caudal mesenteric artery – supplies intestines
R & L external iliac artery – supplies hindlimb
R & L femoral artery – supplies hindquarter
R & L saphenous artery – supplies medial gaskin and paw
R & L popliteal artery – deep and lateral gaskin and paw
R & L internal iliac artery – supplies pelvic organs and muscles
Caudal artery – supplies tail
PULMONARY CIRCUIT
Pulmonary Trunk
R & L pulmonary arteries
Pulmonary capillaries
R & L pulmonary veins
FETAL CIRCULATION
Examine the models and diagrams of the heart and fetal circulation and be able to define
and identify (where possible) the following.
VENOUS CIRCULATION:
Umbilical vein (from placenta - oxygenated)
some blood – Hepatic portal system ----> caudal vena cava
most bypasses liver – Ductus venosus ----> caudal vena cava
HEART:
Foramen ovale (fossa ovalis when closed)
R atrium  L atrium
ARTERIAL CIRCULATION:
Ductus arteriosus (ligamentum arteriosum when closed)
pulmonary trunk  aorta
caudal aorta or iliac arteries
R & L umbilical arteries  placenta
