Swelling is often most visible in the feet and ankles. Pregnancy can cause edema in the legs as the uterus puts pressure on the vena cava, a major blood vessel that returns blood to the heart from the legs. Fluid retention during pregnancy also can be caused by a more serious condition called preeclampsia. Low protein levels in the blood caused by malnutrition, kidney and liver disease can cause edema. The proteins help to hold salt and water inside the blood vessels so fluid does not leak out into the tissues.
Tinky Winky (played by Dave Thompson, Mark Heenehan, and Simon Shelton) is the first Teletubby. He is the largest of the Teletubbies, is covered in bright purple terrycloth, and has a triangular antenna on his head.
Characters Tinky-Winky The largest of the four teletubbies. He is purple, and has a triangle antenna (because of these features, critics assume he is gay, but rest assure, he isn't, he may be a tom-girl, but he's not gay.) His favorite thing is his hand-bag which he can amazingly fit large things in.
