GENERAL HISTOLOGY

Detailed explanation-1: -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-2: -In comparison, the lymphatic system is a linear system in which the lymphatic capillaries at the peripheral tissues drain the fluid (lymph) containing cells, proteins, and macromolecules and transport it back to the blood vascular system through the lymphatic–blood junction at the end of the thoracic duct.

Detailed explanation-3: -The major lymphatic vessels are: The thoracic duct: It begins near the lower part of the spine and collects lymph from the pelvis, abdomen, and lower chest. The thoracic (thuh-RA-sik) duct runs up through the chest and empties into the blood through a large vein near the left side of the neck.
