Rabbit Circulatory System

vein that drains body posterior to diaphragm

vein that drains body anterior to diaphragm

accepts oxygen-depleted blood from body (via vena cava)

• mostly ventrally located
• contracts to pump blood to lungs via pulmonary trunk

accepts oxygen-rich blood from lungs

• mostly dorsally located
• contracts to pump blood to body via aorta

right atrium

with the ventral aorta becomes the base of the pulmonary trunk and aortic arch

• branches into linguofacial, maxillary cranially and the axillary laterally
• posteriorly from the cranial vena cava

• from the external jugular
• runs from heart to face

• from external jugular
• branches to supply blood to jaw region

• drain pectoral and armpit region
• from external jugular/cranial vena cava

branches immediately off the cranial vena cava looping posteriorly to drain the rib region

• first branch off the aortic arch
• splits into right subclavian and paired common carotid arteries

supply head, neck and brain

• second branch off aortic arch
• (with R) supplies armpit and pectoral region

blood flow from aorta to gut to liver via hepatic portal vein back to heart via caudal vena cava

main artery that supplies blood to organs and tissues posterior to the heart

branches off aorta and supplies most of foregut

• arteries branch off aorta
• veins merge into hepatic portal vein
• supply and drain midgut

• arteries branch off aorta
• veins merge into hepatic portal vein
• supply and drain hindgut

• arteries branch off aorta
• veins merge into caudal vena cava
• supply and drain kidneys

• arteries branch off aorta
• veins merge into caudal vena cava
• supply and drain gonads

• arteries branch off common iliac artery
• veins merge into caudal vena cava
• go into hind legs as femoral arteries and veins

• arteries branch off common iliac artery
• veins merge into caudal vena cava
• supply muscles and viscera of pelvic region and reproductive organs
