What would happen if the lymphatic System was not invovled with the Circulatory System?

The lymphatic system drains approximately 10% of the interstitial fluid that has difused out of the capillaries and it transports this back to the subclavian vein.  By this way, the lymphatic system also returns albumin, the main protein found in the circulatory system, back into the venous system.  Without an efficient lymph system in the lungs, fluid would fill up from diffusing out of the capillary beds creating a longer distance that oxygen gas has to travel from the alveolae to the red blood cells in the venous side of the capillary bed.  This is called pulmonary edema and is lethal if bad enough because oxygen fails to successfully difuse to RBCs.

lymphatic system is a part of aur immune system. all lymphamtics eventualy drain into the vena cava nand maintal blood volume. actually lymphatics, vain and artery run parellal to each other. but vain and artery r atteched to each other through cappilaries. but lymohatics r closed at tthe end. the collects the iterstitail fluid and circulate this to vena cava and ultimately to heart. interstitial fluid contain many waste product which r need to eleminate.
     the fluid of lymphatics move with the help of body movement only. if u disconnect the connection between heart and lymphatics the will keep swalloing untill patient die.

Lymph contains fluid derived from white blood corpuscles .These and immunoglobulins in lymph jointly fight infection in the body. Lymphatic system has three interrelated functions: (1) removal of excess fluids from body tissues, (2) absorption of fatty acids and subsequent transport of fat, chyle, to the circulatory system and, (3) production of immune cells (such as lymphocytes, monocytes, and antibody producing cells called plasma cells)
Blood becomes ineffective in fighting infection and allergy without lymph

The capillaries through which exchange occurs has 2 ends- arterial & venous. At the arterial end, some fluid enters the tissue space for exchange & this fluid re-enters the venous end. The fluid that remains in the tissue spaces has to be removed to prevent oedema- excess fluid in the tissue space. It is here that our lymphatics arise. They arise as a blind ended tube wherever there r capillaries, take up the excess fluid from the tissue spaces and drain it into the heart thereby maintaining the volume of the circulatory system. Also lymph nodes r present in the lymphatics which help to check infections.
