The venous system always carries blood back to the heart.
Superior vena cava and the inferior vena cava
The lymphatic system conducts fluid from the interstitial space back to the venous system. It consists of a network of vessels and lymph nodes that help transport excess fluid, waste products, and immune cells from tissues back into the bloodstream.
Factors that directly influence venous blood flow include venous pressure, intrathoracic pressure changes during respiration, skeletal muscle contractions, venous valves, and sympathetic nervous system activity. These factors help propel blood back to the heart against gravity.
Syndromes related to venous insufficiency are caused by valve incompetence. Venous insufficiency is a chronic (long term) condition
our total blood volume is unevenly distributed amongst the arteries, veins and capillaries. The heart, arteries , pulmonary and systemic circuits contain about 1.5 liters of whole blood. The venous system contains 3.5 liters, which is circulating within the liveer, bone marrow and skin.
Yes, 65-70% of the blood volume is in the venous system.

Very simply put the venous system, the arterial system and your heart. The venous system bring blood from your organs and extremities to your heart, which pumps it and the arterial system takes it from your heart to your organs and extremities.

Contraction of veins would increase venous return to the right atrium. It would increase the efficiency of the heart pumping.
The thoracic duct joins the venous system at the junction of the left subclavian vein and the internal jugular vein, near the base of the neck.

Your venous system certainly falls in the category along with your arterial system.
