This vessel branches off the left ventricle and carries oxygenated blood to the systemic arteries.
Arch of the aorta
The most superior portion of the aorta, lying between the ascending and descending segments.
The regional name of the descending aorta as it travels through the thorax. It sends off numerous small arteries, called the visceral and parietal branches, which supply thoracic visceral and body wall structures.
The regional name of the descending aorta as it travels through the diaphragm and enters the abdomen.
The first large artery arising from the arch of the aorta. It carries oxygenated blood to the neck, head, and right upper limb.
Right common carotid artery
This vessel branches off the brachiocephalic trunk to supply structures in the neck and head.
Left common carotid artery
This is the second branch of the arch of the aorta that supplies structures in the neck and head.
Right subclavian artery
This vessel branches off the brachiocephalic trunk and gives rise to a number of vessels that supply the brain, spinal cord, neck, shoulder, thoracic muscle wall, and scapular muscles.
Left subclavian artery
This is the third and final branch of the arch of the aorta that gives rise to a number of vessels that supply the brain, spinal cord, neck, shoulder, thoracic muscle wall, and scapular muscles.
These vessels are major branches off the subclavian arteries and ascend through the cervical foramina of the cervical vertebrae; they supply the posterior portion of the cerebrum, cerebellum, pons, and inner ear.
Right coronary artery
This vessel branches anteriorly to the marginal branch (which supplies the right ventricle) and posteriorly to the posterior interventricular branch (which supplies both ventricles).
Left coronary artery
This vessel branches anteriorly to the anterior interventricular branch (which supplies both ventricles) and the circumflex branch (which supplies the left atrium and left ventricle).
This vessel is a branch of the right coronary artery that supplies oxygenated blood to the wall of the right ventricle.
Posterior interventricular branch
This vessel is a branch of the right coronary artery that supplies oxygenated blood to both ventricles.
Anterior interventricular branch
This vessel is a branch of the left coronary artery that supplies oxygenated blood to both ventricles.
Left anterior descending branch
This is another name for the anterior interventricular branch of the left coronary artery.
This vessel is a branch of the left coronary artery that supplies the left atrium and left ventricle.
External carotid arteries
The more superficial branches of the common carotid arteries, that serve as the major suppliers of blood to all of the structures of the head and neck (except the brain).
Internal carotid arteries
The deeper branches of the common carotid arteries that enter the cranial cavity through the carotid foramen. They then produce a number of branches inside the cranial cavity, including branches that lead into the Circle of Willis.
This artery forms from the merging of the right and left vertebral arteries, and runs under the base of the brain. It carries blood into the Circle of Willis, and also gives rise to branches which supply different regions of the brain including the posterior cerebrum, cerebellum, pons, and inner ear.
Circle of Willis
This provides alternate detours for blood flow to the brain in case arteries become blocked or damaged, as well as helping to equalize blood pressure to the brain.
Cerebral arterial circle
This is another name for the Circle of Willis
These vessels are continuations of the subclavian arteries. They give rise to numerous branches that supply muscles of the thorax, shoulder, scapula, and humerus.
These vessels are continuations of the axillary arteries into the arm and are common sites for blood pressure measurement. They supply muscles of the arm, humerus, and elbow joint.
These vessels are continuations of the brachial arteries, and pass along the lateral aspect of the forearms to enter the wrists. They are a major blood source to muscles of the posterior compartment of the forearm.
These vessels branch off the brachial arteries and pass along the medial aspect of the forearms and then into the wrists. They are a major blood source to muscles of the anterior compartment of the forearm.
Superficial palmar arches
These vessels, which extend across the metacarpals, are formed mainly by a branch of the ulnar artery, and partly by a branch of the radial artery. They supply muscles, bones, joints, and skin of the palm and fingers.
This vessel is also called the thoracic aorta (as it moves through the thoracic cavity), and the abdominal aorta (as it moves through the abdominal cavity).
Posterior intercostal arteries
Nine pairs of arteries that branch off the thoracic aorta, and pass laterally and then anteriorly through the spaces between the ribs. They supply the skin, muscles, and ribs of the thoracic wall, along with the thoracic vertebrae, meninges, spinal cord, and mammary glands.
Superior phrenic arteries
These vessels arise from the lower end of the thoracic aorta and pass onto the superior surface of the diaphragm. They supply the diaphragm muscle and pleura covering the diaphragm.
Inferior phrenic arteries
These vessels are the first paired branches of the abdominal aorta. They supply the diaphgram and suprarenal (adrenal) glands.
This artery is the first branch of the abdominal aorta, and divides into three branches: the left gastric, splenic, and common hepatic arteries. It supplies all of the GI tract (from the abdominal part of the esophagus to the duodenum) and spleen.
Left gastric artery
This is the smallest of the three celiac branches, arising superiorly to the left. It supplies the lesser curvature of the stomach and the abdominal part of the esophagus.
This is the largest branch of the celiac trunk, arising from the left side of the trunk and then passes horizontally to the spleen. It and its branches supply the spleen, pancreas, and greater curvature of the stomach.
Common hepatic artery
This is the branch of the celiac trunk that arises from the right side of the trunk. It and its branches supply the liver, gallbladder, stomach, pancreas, and duodenum.
Proper hepatic artery
This is a branch of the common hepatic artery that ascends along the bile ducts to supply the liver and gallbladder.
Right gastric artery
This is a branch of the common hepatic artery that curves back to the left to supply the lesser curvature of the stomach.
Superior mesenteric artery
This branch of the abdominal aorta located 1 cm below the celiac trunk (near L1) branches extensively into the portions of the peritoneum that attach the small intestine to the posterior abdominal wall. It supplies the organs of the GI tract from the duodenum to the transverse colon.
Inferior mesenteric artery
This branch of the abdominal aorta, arising near L3, branches extensively and supplies the organs of the GI tract from the transverse colon to the rectum.
These paired arteries branch off the abdominal aorta (near L1) and supply the adrenal glands.
These paired arteries branch off the abdominal aorta (near L2), about 1 cm below the superior mesenteric artery, and supply all of the tissues of the kidneys.
These paired arteries branch off the abdominal aorta (near L2), just below the renal arteries. They supply the reproductive organs.
This is the specific name of the gonadal arteries in females, supplying the ovaries, uterine (fallopian) tubes, and ureters.
This is the specific name of the gonadal arteries in males, supplying the testis, epididymis, ductus deferens, and ureters.
Common iliac arteries
These arteries arise at the end of the abdominal aorta (near L4), and branch into the external and internal iliac arteries. They supply the pelvic muscle wall, pelvic organs, external genitals, and lower limbs.
Internal iliac arteries
These primary arteries of the pelvis branch off the common iliac arteries (near the sacroiliac joint) and descend into the pelvis. They supply the pelvic muscle wall, pelvic organs, buttocks, external genitals, and medial muscles of the thigh.
External iliac arteries
These are the larger branches of the common iliac arteries, descending along the psoas major muscles, and become the femoral arteries as they enter the thigh. They supply the lower abdominal wall and lower limb.
These are a continuation of the external iliac arteries as they enter the thigh. They supply the muscles of the thigh (quadriceps, adductors, and hamstrings), femur, and ligaments and tendons around the knee joint.
These are a continuation of the femoral arteries as they enter the space behind the knee. They divide into the anterior and posterior tibial arteries. They supply the muscles of the distal thigh, skin of the knee region, muscles of the proximal leg, knee joint, femur, patella, tibia, and fibula.
Anterior tibial arteries
These branch off and descend from the popliteal arteries into the anterior muscle compartment of the leg. They and their branches supply the tibia, fibula, anterior muscles of the leg, dorsal muscles of the foot, tarsal bones, metatarsal bones, and phalanges.
Dorsalis pedis arteries
These are continuations of the anterior tibial arteries at the ankles. They supply the dorsal muscles of the foot and tarsal bones.
These branch off the dorsalis pedis arteries on the dorsum of the foot, and run laterally over the bases of the metatarsals. They supply the tarsal bones and metatarsal bones.
Posterior tibial arteries
These are a direct continuation of the popliteal arteries and descend into the posterior muscle compartment of the legs deep to the soleus muscles. They and their branches supply the posterior and lateral muscle compartments of the legs, plantar muscles of the foot, tibia, fibula, tarsal, metatarsal, and phalanges bones.
These arise from the posterior tibial arteries in the upper third of the leg, and course laterally as they descend and supply the lateral compartment of the leg. They are also called the peroneal arteries.
