List of Arteries in the Human Body

The human circulatory system is a complex network of blood vessels that includes arteries, veins, and capillaries. Arteries are blood vessels that carry oxygen-rich blood away from the heart to all parts of the body. This article provides a comprehensive list of the major arteries in the human body, categorized by the regions they supply.

Major Arteries

Aorta

The Aorta is the largest artery in the body. It originates from the left ventricle of the heart and extends down to the abdomen, where it splits into the common iliac arteries. The aorta is divided into four main sections:

• Ascending aorta
• Aortic arch
• Descending thoracic aorta
• Abdominal aorta

Coronary Arteries

The coronary arteries supply blood to the heart muscle. The two main coronary arteries are:

• Left coronary artery (LCA)
• Right coronary artery (RCA)

Carotid Arteries

The carotid arteries supply blood to the brain, neck, and face. They are divided into:

• Common carotid artery
• Internal carotid artery
• External carotid artery

Arteries of the Upper Limb

The main arteries supplying the upper limb include:

• Subclavian artery
• Axillary artery
• Brachial artery
• Radial artery
• Ulnar artery

Arteries of the Lower Limb

The lower limb arteries provide blood to the lower parts of the body and include:

• Common iliac artery
• Femoral artery
• Popliteal artery
• Anterior tibial artery
• Posterior tibial artery
• Dorsalis pedis artery

Pulmonary Arteries

The pulmonary arteries are responsible for carrying deoxygenated blood from the right ventricle of the heart to the lungs for oxygenation.

Cerebral Arteries

The brain receives its blood supply from two pairs of vessels:

• Internal carotid arteries
• Vertebral arteries

These arteries further branch into the anterior cerebral artery, middle cerebral artery, and posterior cerebral artery, among others.

Abdominal Arteries

The abdominal region is supplied by several arteries branching from the abdominal aorta, including:

• Celiac trunk
• Superior mesenteric artery
• Inferior mesenteric artery
• Renal arteries
• Gonadal arteries (testicular or ovarian)

Conclusion

The arteries of the human body are essential for the delivery of oxygen-rich blood to tissues and organs. Understanding the major arteries and their functions can aid in the comprehension of the circulatory system's role in health and disease.
