IMMUNOLOGY

Detailed explanation-1: -The collecting vessels merge and empty lymph into the bloodstream by way of the thoracic duct at its entry into the left subclavian vein or by the right lymphatic duct, which empties into the right subclavian vein.

Detailed explanation-2: -After collecting in the cisterna chyli, lymph flows proximally through the thoracic duct, and ultimately empties in the venous circulation at the junction of the left internal jugular and subclavian veins.

Detailed explanation-3: -Blood Supply and Lymphatics 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-4: -In a healthy body, the lymphatic channels from the liver and mesentery drain toward the thoracic duct, which is the main lymphatic vessel responsible for lymph drainage. In most people, the thoracic duct drains into the subclavian vein on the left side.

Detailed explanation-5: -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.

Detailed explanation-6: -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.
