Transcript text: Which vein drains blood from the axillary and smaller local veins near the scapular region?
- Internal jugular vein
- Subclavian vein
- Brachiocephalic vein
- External jugular vein
Solution
The answer is the second one: Subclavian vein.
Explanation for each option:
Internal jugular vein: This vein primarily drains blood from the brain, face, and neck, not from the axillary or scapular region.
Subclavian vein: This vein is responsible for draining blood from the axillary vein and smaller veins near the scapular region. It collects blood from the arm and shoulder area, making it the correct answer.
Brachiocephalic vein: This vein is formed by the union of the subclavian and internal jugular veins. It drains blood from the head, neck, and upper limbs into the superior vena cava, but it is not directly responsible for draining the axillary or scapular region.
External jugular vein: This vein drains blood from the outer structures of the head and neck, not from the axillary or scapular region.
In summary, the subclavian vein is the correct answer as it directly drains blood from the axillary and smaller local veins near the scapular region.
