IMMUNOLOGY

Detailed explanation-1: -Most of the lymphatic vessels have valves like those in veins to keep the lymph, which can clot, flowing in the one direction (toward the heart). Lymphatic vessels drain fluid called lymph from tissues throughout the body and return the fluid to the venous system through two collecting ducts.

Detailed explanation-2: -Lymphatic vessels: Lymphatic vessels are the network of capillaries (microvessels) and a large network of tubes located throughout your body that transport lymph away from tissues. Lymphatic vessels collect and filter lymph (at the nodes) as it continues to move toward larger vessels called collecting ducts.

Detailed explanation-3: -Similar to other organs, the heart relies on cardiac lymphatics to drain tissue fluid in order to maintain the steady-state interstitial fluid equilibrium. Myocardial contractions help to propel cardiac lymphatic flow.
