Venen des Thorax

The video tutorial provides an in-depth exploration of the thorax's vascular system, focusing on the anatomy and function of various veins, including the superior vena cava, azygos system, pulmonary veins, and esophageal veins. It explains the role of these veins in circulation, particularly in conditions like portal hypertension. The tutorial also covers the intercostal veins and their significance, concluding with a discussion on the heart veins and the coronary sinus.

Which valve is located at the transition to the right ventricle?

• Mitral valve

• Tricuspid valve

• Pulmonary valve

• Aortic valve

What is the primary function of the azygos system?

• To drain the organs of the mediastinum and thorax wall

• To supply oxygen to the heart

• To transport nutrients to the lungs

• To regulate blood pressure

Which vein is known for carrying oxygen-rich blood?

• Azygos vein

• Pulmonary veins

• Inferior vena cava

• Superior vena cava

What condition is associated with increased blood flow through the esophageal veins?

• Pulmonary embolism

• Myocardial infarction

• Portal hypertension

• Aortic aneurysm

Where does the internal thoracic vein run parallel to?

• The pulmonary artery

• The internal thoracic artery

• The superior vena cava

• The azygos vein

Which vein collects blood from the second to fourth intercostal spaces?

• Superior intercostal vein

• Inferior vena cava

• Pulmonary vein

• Azygos vein

What is the role of the coronary sinus?

• To regulate heart rate

• To drain blood from the heart veins

• To transport nutrients to the heart

• To supply oxygen to the heart

Which cardiac vein is the largest?

• Coronary sinus

• Cardiac vein magna

• Cardiac vein media

• Cardiac vein parva

Where does the vena cardiaca media originate?

• In the right ventricle

• In the left atrium

• In the apex of the heart

• At the base of the heart

Which vein runs in the sulcus coronarius on the right side?

• Coronary sinus

• Vena cardiaca parva

• Vena cardiaca media

• Vena cardiaca magna
