ANATOMY

Detailed explanation-1: -Lymph capillaries help keep the overall fluid balance in your body. Throughout your body, interstitial fluid (fluid found in the spaces around cells) leaks from blood capillaries into your tissues. Lymph capillaries pick up this fluid and help return it to your circulatory system.

Detailed explanation-2: -Lymph fluid can only flow forward through lymphangions due to the closing of valves after fluid is pushed through by fluid accumulation, smooth muscle contraction, or skeletal muscle contraction.

Detailed explanation-3: -It leaks out of the capillary walls because of pressure exerted by the heart or osmotic pressure at the cellular level. As the interstitial fluid accumulates, it is picked by the tiny capillary lymphatics, passes through the lymph nodes, and finally returns the fluid to the venous circulation.

Detailed explanation-4: -Fluid in the spaces between tissues is called interstitial fluid, or ‘tissue fluid’. This provides the cells of the body with nutrients (via the blood supply) and a means of waste removal.
