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.
By the time of the programme's cancellation, Teletubbies toys had generated over Â£200 million in revenue for co-creator Anne Wood alone. In 2005, Chris Hastings and Ben Jones of The Daily Telegraph called Teletubbies the most lucrative show in BBC television history..
