MICROANATOMY

Detailed explanation-1: -The left subclavian trunk directly drains into the thoracic duct, and the right subclavian trunk continues to form the right lymphatic duct, which enters at the right venous angle (junction of the internal jugular vein and subclavian vein).

Detailed explanation-2: -In over 95% of cases, the thoracic duct terminates in the internal jugular vein, the subclavian vein, or the angle between the two.

Detailed explanation-3: -Your subclavian vein is a deep vein that moves oxygen-poor blood from your upper body back to your heart. You have one on each side of your body. Your right subclavian vein carries blood from your right upper body. Your left subclavian vein carries blood from your left upper body.

Detailed explanation-4: -The lymphatic vessels drain into collecting ducts, which empty their contents into the two subclavian veins, located under the collarbones. These veins join to form the superior vena cava, the large vein that drains blood from the upper body into the heart.
