Intercostal veins

The video tutorial explains the anatomy and function of intercostal veins, focusing on their role in draining blood from intercostal spaces to the heart. It covers the azygos system of veins, including the azygos, hemiazygos, and accessory hemiazygos veins, and their pathways. The tutorial also discusses the internal thoracic vein and the concept of anastomosis in intercostal veins.

What is the primary function of intercostal veins?

• To support the diaphragm

• To connect the ribs to the sternum

• To supply oxygen to the ribs

• To drain blood from intercostal spaces

Which system of veins does blood from the back intercostal veins drain into?

• Jugular veins

• Azygos system of veins

• Coronary veins

• Pulmonary veins

What is the role of the azygos vein in the azygos system?

• To supply blood to the heart

• To transport oxygenated blood to the brain

• To drain blood from the right intercostal spaces

• To connect the left and right lungs

What is the function of the internal thoracic vein?

• To drain blood from the posterior intercostal veins

• To supply blood to the diaphragm

• To collect blood from anterior intercostal veins

• To connect the ribs to the sternum

Into which vein does the internal thoracic vein drain?

• Brachiocephalic vein

• Superior vena cava

• Inferior vena cava

• Pulmonary vein

What is the significance of anastomosis in intercostal veins?

• It connects the azygos and hemiazygos veins

• It supplies oxygen to the intercostal spaces

• It allows for the union of anterior and posterior intercostal veins

• It prevents blood flow between veins

Which veins drain the left upper intercostal spaces?

• Pulmonary vein

• Azygos vein

• Accessory hemiazygos vein
