The Iliac Artery is a major blood vessel that supplies the pelvis and legs. It begins where the abdominal aorta divides in the lower abdomen. Clinicians commonly refer to it in vascular disease, imaging, and catheter-based procedures. It is also an important “route” for many minimally invasive cardiovascular interventions.

The Mesenteric Artery refers to arteries that carry oxygen-rich blood to the intestines. These vessels are part of the body’s arterial circulation, which is closely tied to cardiovascular health. Clinicians most often discuss the Mesenteric Artery when evaluating abdominal pain, intestinal blood flow, or vascular blockages. It is also referenced during imaging and procedures that diagnose or restore blood supply to the gut.

The Renal Artery is a major blood vessel that carries oxygen-rich blood from the aorta to the kidney. Most people have one Renal Artery supplying each kidney, but normal variations are common. It is frequently referenced in cardiovascular and kidney-related evaluations because kidney blood flow affects blood pressure and fluid balance. Clinicians assess the Renal Artery in conditions such as renovascular hypertension and atherosclerotic vascular disease.

The Brachiocephalic Artery is a large blood vessel that comes off the aortic arch. It carries oxygen-rich blood toward the right side of the head, neck, and right arm. It is also called the brachiocephalic trunk or innominate artery in some texts. Clinicians reference it in imaging, vascular exams, and certain heart and chest procedures.

The Subclavian Artery is a major artery in the upper chest that supplies blood to the arm. It also contributes to blood flow toward the neck and brain through key branches. Clinicians commonly reference it during vascular exams, blood pressure comparison between arms, and imaging. It is also an important vessel in some catheter-based and surgical cardiovascular procedures.

The Vertebral Artery is a paired artery in the neck that carries oxygen-rich blood toward the back of the brain. Each Vertebral Artery usually arises from a subclavian artery and travels upward alongside the cervical spine. The right and left Vertebral Artery join to form the basilar artery, an important vessel for brain circulation. Clinicians commonly refer to the Vertebral Artery during stroke evaluation, vascular imaging, and cervical/neck assessments.

The **External Carotid Artery** is one of the two main branches of the common carotid artery in the neck. It primarily supplies blood to the face, scalp, jaw, tongue, and parts of the neck. Clinicians often reference it during head-and-neck vascular assessment and carotid imaging. It is also important for understanding stroke workups, even though it is not the usual direct source of brain blood flow.

The Internal Carotid Artery is a major artery in the neck that carries oxygen-rich blood to the brain. It begins at the carotid bifurcation, where the common carotid artery divides into internal and external branches. It is commonly discussed in stroke and transient ischemic attack (TIA) evaluation. It is also a key focus in vascular imaging and carotid artery disease care.

The Carotid Artery is a major blood vessel in the neck that supplies blood to the brain and face. Most people have a right and a left Carotid Artery. Clinicians commonly assess the Carotid Artery when evaluating stroke risk and neurologic symptoms. It is also referenced in imaging, vascular exams, and some procedures to restore blood flow to the brain.

Inferior Vena Cava is the body’s largest vein that carries blood back to the heart. It runs through the abdomen and chest and drains into the right atrium. Clinicians commonly reference it in imaging, heart failure evaluation, and venous clot care. It is also an important pathway for catheters and certain cardiovascular procedures.

The Superior Vena Cava is a large vein that carries blood back to the heart. It returns oxygen-poor blood from the head, neck, arms, and upper chest. It drains into the right atrium, the heart’s right-sided collecting chamber. Clinicians commonly refer to it during imaging, central line placement, and evaluation of venous blockage.

Pulmonary Veins are blood vessels that carry oxygen-rich blood from the lungs to the heart. They typically drain into the left atrium, one of the heart’s upper chambers. They are discussed in cardiology when evaluating oxygenated blood flow, left-sided heart pressures, and certain rhythm disorders. They are also an important focus in heart imaging and catheter-based procedures.

The Pulmonary Trunk is the large blood vessel that carries blood from the right ventricle of the heart to the lungs. It is sometimes called the “main pulmonary artery.” It sits just above the pulmonary valve and then divides into the right and left pulmonary arteries. Clinicians refer to it frequently in heart imaging, congenital heart disease care, and pulmonary hypertension evaluation.

The Pulmonary Artery is the large blood vessel that carries blood from the right side of the heart to the lungs. It starts as the main pulmonary artery (pulmonary trunk) and then divides into right and left branches. Its job is to deliver blood to the lungs so carbon dioxide can be removed and oxygen can be added. Clinicians commonly reference the Pulmonary Artery in imaging, heart catheterization, and evaluation of shortness of breath.

The Abdominal Aorta is the largest artery in the abdomen. It is the continuation of the main body artery (the aorta) after it passes through the diaphragm. It supplies oxygen-rich blood to abdominal organs, the pelvis, and the legs. It is commonly referenced in vascular exams and imaging for aneurysm, blockage, or dissection.

The Thoracic Aorta is the portion of the aorta that runs through the chest. It is the body’s main artery, carrying oxygen-rich blood from the heart to the rest of the body. Clinicians reference the Thoracic Aorta when evaluating chest pain, aortic enlargement, or inherited aortic conditions. It is also a key focus in cardiovascular imaging and in some catheter-based or surgical repairs.

The Descending Aorta is the portion of the aorta that carries oxygen-rich blood downward from the heart toward the lower body. It begins after the aortic arch and continues through the chest and abdomen before branching to supply major organs and the legs. Clinicians refer to it frequently in heart and vascular imaging, emergency care, and aortic disease evaluation. It is a normal anatomic structure, but it can be affected by conditions such as aneurysm, dissection, and atherosclerosis.

The Aortic Arch is the curved part of the aorta, the body’s main artery. It sits in the upper chest between the ascending and descending aorta. It gives rise to major arteries that supply blood to the brain and arms. Clinicians discuss it often in cardiovascular imaging, surgery, and aortic disease care.

The Ascending Aorta is the first portion of the aorta, the body’s main artery. It begins at the aortic valve, where blood exits the left ventricle. It carries oxygen-rich blood upward before the aorta curves into the aortic arch. Clinicians commonly assess it on heart imaging and during evaluation of aortic disease.

The Aorta is the body’s main artery that carries oxygen-rich blood from the heart to the rest of the body. It begins at the left side of the heart and then travels through the chest and abdomen. Clinicians refer to the Aorta in heart and vascular imaging, blood pressure evaluation, and emergency care. Many cardiovascular conditions are defined by where they involve the Aorta and how they affect blood flow.
