From which artery does the vertebral artery arise? Which is the major vein draining the tissues of the head and upper body? Which of the following do the right and left brachiocephalic veins unite to form? Which of the following does the right axillary vein run into?
Understand the Problem
The questions are asking about the origins and functions of certain arteries and veins in the human body, specifically relating to the vascular system and circulation.
Answer
43: Subclavian, 44: Internal jugular, 45: Superior vena cava, 46: Right subclavian vein
The vertebral artery arises from the subclavian artery. The major vein draining the tissues of the head and upper body is the internal jugular vein. The right and left brachiocephalic veins unite to form the superior vena cava. The right axillary vein runs into the right subclavian vein.
Answer for screen readers
The vertebral artery arises from the subclavian artery. The major vein draining the tissues of the head and upper body is the internal jugular vein. The right and left brachiocephalic veins unite to form the superior vena cava. The right axillary vein runs into the right subclavian vein.
More Information
The vertebral arteries originate from the subclavian arteries, which provide significant blood flow to the neck and brain. The superior vena cava is a crucial part of systemic circulation, carrying deoxygenated blood from the upper body to the heart.
Tips
A common mistake is confusing the roles and connections of major arteries and veins. Reviewing anatomical diagrams can help clarify these relationships.
