Veins and Their Functions

The video tutorial provides a comprehensive overview of the major veins that transport deoxygenated blood to the right atrium. It covers the superior and inferior vena cava, the hepatic portal system, and the renal and gonadal veins. The tutorial also explains the formation of the brachiocephalic veins, subclavian vein, and the veins of the upper and lower limbs, highlighting their significance in the circulatory system.

Which vein collects deoxygenated blood from the heart wall and empties it into the right atrium?

• Pulmonary vein

• Inferior vena cava

• Superior vena cava

• Coronary sinus

What forms the superior vena cava?

• Brachiocephalic veins

• Jugular veins

• Axillary veins

• Subclavian veins

Which vein drains blood from the cranial cavity?

• Subclavian vein

• Internal jugular vein

What is the significance of the median cubital vein?

• It drains blood from the liver
