Arteries, Veins

Circulatory System - Fetal Pig: Network of blood vessels throughout body.

Veins of Fetal Pigs: Cranial vena cava, brachiocephalic veins, internal jugular vein, external jugular veins, cephalic veins, subclavian veins, axillary veins, subscapular veins, caudal vena cava, hepatic portal vein, umbillical vein, renal veins, common iliac veins, internal iliac veins, external iliac veins, femoral veins, and deep femoral veins.

Cranial Vena Cava: Large vein carrying blood from head, neck and forelimbs to right atrium.

(innominate veins) Brachiocephalic Veins: Carry blood from the cephalic, subclavian, and jugular veins to the cranial vena cava.

Internal Jugular Vein: 1st set of vessels to emerge from cranial vena cava, medially. Carry blood from head to brachioencephalic veins. Located on either side of trachea.

External Jugular Veins: 2nd set of vessels to emerge from cranial vena cava, medially. Carry blood from head to brachioencephalic veins.

Cephalic Veins: 3rd vessels to emerge from cranial vena cava, medially. Carry blood from forelimb to brachioencephalic veins.

Subclavian Veins: 4th set of vessels to emerge from cranial vena cava, medially. Carry blood from the subscapular veins and axillary veins to brachioencephalic veins.

Axillary Veins: Carry blood from forelimbs and join with subscapular veins to form subclavian vein.

Subscapular Veins: Carry blood from region of armpit and join with axillary vein to form subclavian vein.

Caudal Vena Cava: Large vein carrying blood from posterior portion of body to right atrium.

Hepatic Portal Vein: Large vein (may be yellow). Located between stomach and liver. Carries blood from stomach, spleen, pancreas, and intestines to liver.

Umbillical Vein: Carries blood containing oxygen and nutrients from placenta to fetus.

Renal Veins: Carry blood from kidneys to caudal vena cava.

Common Iliac Veins: Carry blood from external and interal iliac veins to caudal vena cava.

Internal Iliac Veins: Carry blood from pelvis to common iliac veins.

External Iliac Veins: Veins carry blood from femoral and deep femoral veins to common iliac veins.

Femoral Veins: Carry blood from the thigh and lower hind to external iliac veins.

Deep Femoral Veins: Carry blood from thigh to external iliac veins.

Arteries of Fetal Pig: Aortic Arch, Brachiocephalic Trunk, Left Subclavian Artery, Carotid Trunk, Common Carotid Arteries, External Carotid Artery, Internal Carotid Arteries, Right Subclavian Artery, Axillary Arteries, Brachial Artery, Aorta, Celiac Trunk, Cranial Mesenteric Artery, Renal Arteries, Caudal Mesenteric Artery, Umbillical Arteries, External Iliac Arteries, Internal Iliac Arteries, Femoral Arteries, Deep Femoral Ateries.

Aortic Arch: Artery that leaves left ventricle and gives rise to the brachiocephalic trunk, left subclavian artery, and aorta.

Brachioencephalic Trunk: 1st large artery arising from aortic arch. Carries oxygenated blood to neck, head, and right forelimb.

Left Subclavian Artery: 2nd large artery arisig from aortic arch. Carries blood or left forelimb.

Carotid Trunk: 1st vessel to arise from right brachiocephalic trunk, medially. Carries blood anteriorly towards neck and head.

Common Carotid Arteries: Carotid trunk splits into right and left common carotid arteries.

External Carotid Artery: Arteries are medial branches of common carotid arteries. Carry blood to area around masseter muscle and chin.

Internal Caroltid Arteries: Laternal branches of common carotid arteries. Carry blood to brain.

Right Subclavian Artery: 2nd arteries to arise from right brachioencephalic trunk. Supplies blood to cervical vertebrae and right forelimb.

Axillary Arteries: Continuation of subclavian arteries. Carry blood to armpit, shoulder, and forelimb.

Brachial Artery: Arise from axillary arteries and carry blood into the forelimbs.

Aorta: Large vessel lying on mid-dorsal wall, length of abdominal cavity. Carries blood to entire posterior portion of body.

Celiac Trunk: 1st artery to branch off aorta, posterior to diaphragm. Carries blood to stomach, pancreas, and spleen.

Cranial Mesenteric Artery: 2nd artery to branch off aorta, posterior to diaphragm. Carries blood to most of small intestine.

Renal Arteries: 2 large arteries branch off aorta and carry blood to kidneys.

Caudal Mesenteric Artery: Branches off ventral surface of aorta before it splits into umbillical arteries. Carries blood to large interstine and colon.

Umbillical Arteries: Terminal end of aorta splits into these 2 arteries. Enter umbillical cord and carry blood to placenta.

External Iliac Arteries: Branch off aorta immediately anterior to umbillical arteries. Carry blood to thighs and hind limbs.

Internal Iliac Arteries: Branch dorsally off aorta, immediately to umbilical arteries. Carry blood to pelvic region.

Femoral Arteries: 1 of 2 branches of external iliac arteries. Carry blood to thigh and lower hind limb.

Deep Femoral Arteries: 1of 2 branches of external arteries. Carry blood to thigh.
