Blood supply of the esophagus

This tutorial covers the anatomy of blood vessels related to the esophagus, focusing on the aorta and its branches, including the thoracic and abdominal aorta. It explains the esophageal arteries, their connections, and the venous system associated with the esophagus. The video also explores the subclavian and carotid arteries, providing a comprehensive understanding of the vascular network in the thorax and abdomen.

What is the primary function of the diaphragm in relation to the esophagus?

• To protect the heart

• To aid in digestion

• To separate the thorax and abdomen

• To supply blood to the esophagus

Which part of the aorta is responsible for supplying blood to the esophagus?

• Ascending aorta

• Aortic arch

• Thoracic aorta

• Abdominal aorta

Which artery is a branch of the aortic arch and supplies the left side of the head and neck?

• Right common carotid artery

• Left subclavian artery

• Right subclavian artery

• Left common carotid artery

The esophageal branches of which artery form an anastomosis with the inferior thyroid artery?

• Common carotid artery

• Thoracic aorta

• Left gastric artery

• Inferior phrenic artery

What is the function of the posterior intercostal arteries?

• To supply blood to the diaphragm

• To drain blood from the esophagus

• To supply blood to the stomach

• To supply blood to the intercostal spaces

Which artery originates from the celiac trunk and supplies the stomach and spleen?

• Inferior phrenic artery

• Splenic artery

• Left gastric artery

• Common hepatic artery

Which artery is responsible for supplying the liver and parts of the pancreas?

• Left gastric artery

• Common hepatic artery

• Splenic artery

• Inferior phrenic artery

What is the role of the azygous vein in the venous system?

• To drain blood from the lower body

• To drain venous blood towards the superior vena cava

• To supply oxygenated blood to the esophagus

• To transport blood to the left atrium

The inferior vena cava is formed by the joining of which veins?

• Left and right renal veins

• Left and right brachiocephalic veins

• Left and right common iliac veins

• Left and right subclavian veins

Which vein drains the intercostal spaces and is closely related to the posterior intercostal arteries?

• Left gastric vein

• Posterior intercostal vein

• Inferior thyroid vein

• Superior vena cava
