Scolex
Imagine trying to secure a stubborn poster to a wall without it falling off. Just as you need strong tape or hooks to keep that poster firmly attached, a tapeworm uses its scolex to attach itself to the host's intestinal wall. The scolex acts like the hooks or tape, ensuring the tapeworm stays in place by using its suckers or hooks, similar to how you secure the corners of a poster so it doesn’t slide down.
