- Other branches: Bronchial arteries (lungs), Esophageal arteries (esophagus) and Phrenic arteries (diaphragm)
Arterial Branches of the Thoracic Aorta
- First branch of the abdominal aorta.
- Single vessel that has three branches: L gastric artery (stomach), Splenic artery (spleen) and Common hepatic artery (liver)

Lumbar Arteries
Small, unpaired artery supplying the second half of the large intestine.
Arterial branches of the abdominal aorta.
Inferior Mesenteric Artery
- Final branches of the abdominal aorta.
- Each divides into an: Internal iliac artery (pelvic organs - bladder, rectum) and External iliac artery (enters the thigh where it becomes the femoral artery)
Arterial branches of the abdominal aorta.
R and L Common Iliac Arteries
Femoral artery and its branch that serves the thigh.
Arterial branches of the abdominal aorta.
Deep Artery of the Thigh
At the knee, the femoral artery becomes the ____ artery, which then splits into the ____ artery and ____ artery which supply the leg and foot.
Arterial branches of the abdominal aorta.
Politeal, Anterior Tibial and Posterior Tibial
Anterior tibial artery terminates in the ____ artery which via the ____ artery supplies the dorsum of the foot.
Arterial branches of the abdominal aorta.
Dorsalis Pedis, Arcuate
Often palpated in patients with circulatory problems of the legs to determine whether the distal part of the leg has adequate circulation.
Dorsalis Pedis
- Generally located in deep, well-protected body areas.
- More superficial and some are easily seen and palpated on the body surface, naming of these are identical to that of their companion arteries.
- Arteries
- Veins
- Branch off the aorta.
- Converge on the venae cavae which enter the right atrium of the heart.
- Major Systemic Arteries
- Veins
- Veins draining the head and arms empty into.
- Draining the lower body empty into.
- Superior Vena Cava
- Inferior Vena Cava
Distal-to-proximal direction = same direction the blood flows into the superior vena cava.
Veins draining into the superior vena cava.
Veins Draining into the Superior Vena Cava
- Deep veins draining the forearm.
- Unite to form the: Deep brachial vein (drains the arm) and empties into the, Axillary vein (in the axillary region)
Veins draining into the superior vena cava.
Radial Vein and Ulnar Vein
Provides for the superficial drainage of the lateral aspect of the arm and empties into the axillary vein.
Veins draining into the superior vena cava.
Cephalic Vein
Superficial vein that drains the medial aspect of the arm and empties into the brachial vein proximally.
Veins draining into the superior vena cava.
Basilic Vein
Joined at the anterior aspect of the elbow by the median cubital vein.
Veins draining into the superior vena cava.
Basilic and Cephalic Veins
Often chosen as the site for withdrawing blood for the purpose of blood testing.
Veins draining into the superior vena cava.
Median Cubital Vein
Receives venous blood from the arm through the axillary vein and from the skin and muscles of the head through the external jugular vein.
Veins draining into the superior vena cava.
Subclavian Vein
Drains the posterior part of the head.
Veins draining into the superior vena cava.
Vertebral Vein
Drains the dural sinuses of the brain.
Veins draining into the superior vena cava.
Internal Jugular Vein
- Large veins that receive venous drainage from the subclavian, vertebral, and internal jugular veins.
- Join to form the superior vena cava which enters the heart.
Veins draining into the superior vena cava.
R and L Brachiocephalic Veins
Single vein that drains the thorax and enters the superior vena cava just before it joins the heart.
Veins draining into the superior vena cava.
Azygos Vein
Much longer than the superior vena cava and returns blood to the heart from all body regions inferior to the diaphragm.
Inferior Vena Cava
Drain the leg (calf and foot)
Veins draining into the inferior vena cava.
- Anterior Tibial Vein
- Posterior Tibial Vein
- Fibular Vein
Posterior tibial vein becomes the ____ vein at the knee and the ____ vein in the thigh.
Veins draining into the inferior vena cava.
Popliteal, Femoral
Femoral vein becomes the ____ vein as it enters the pelvis.
Veins draining into the inferior vena cava.
External Iliac Vein
- Longest veins in the body.
- Receive the superficial drainage of the leg.
- Begin at the dorsal venous arch in the foot and travel up the medial aspect of the leg to empty into the femoral vein.
Veins draining into the inferior vena cava.
Great Saphenous Veins
- Formed by the union of the external iliac vein and internal iliac vein (drains the pelvis)
- Join to form the inferior vena cava which then ascends superiorly in the abdominal cavity.
