In the following passage, there are blanks, each of which has been numbered. Find out the appropriate word/phrase in each case.

Varicose veins are veins that have become enlarged and twisted. The term commonly refers to the veins on the leg, although varicose veins can occur elsewhere. Veins have pairs of leaflet valves to (21) blood from flowing backwards (retrograde flow or venous reflux). Leg muscles pump the veins to return blood to the heart (the skeletal-muscle pump), (22) the effects of gravity. When veins become varicose, the leaflets of the valves no longer meet properly, and the valves do not work (valvular incompetence). This allows blood to flow backwards and they enlarge even more. Varicose veins are most common in the superficial veins of the legs, which are (23) to high pressure when standing. Besides being a cosmetic problem, varicose veins can be painful, especially when standing. Severe long-standing varicose veins can (24) to leg swelling, venous eczema, skin thickening (lipodermatosclerosis) and ulceration. Although life-threatening complications (25) uncommon, varicose veins may be confused with deep vein thrombosis, which may be life-threatening.
