Answer:

To burrow through the earth, a worm will flex its circular and longitudinal muscles to make itself long, then will extend the setae on its anterior, or front end to anchor itself in the earth. It will then contract its muscles to make its body short and bring the posterior, or back end, closer to the front.

Anestetic [448]


This is the mucus membrane.

Mucus membranes are found lining the body canals and cavities that lead to the outside  namely the respiratory tract and digestive tract as well as the urogenital tract.

Mucous membranes secrete a sticky substance called mucus which is made of a monopoly saccharide called mucin.

The mucus traps pathogens and other particulate matter, preventing them from getting to deeper tissues. Once trapped, these unwanted foreign intruders are expelled outside of the body with the mucus, or swallowed into the stomach where they are destroyed by the strong acid  there.
