When it is in the hollow cell, the hollow cell takes the food and propels it into little tubes, which are lined with flame cells. These flame cells contain small cilia, these cilia pushes the waste from the flame cells to tubules that excrete the waste from the proglottids.
Attachment size limit. You can send up to 25 MB in attachments. If you have more than one attachment, they can't add up to more than 25 MB. If your file is greater than 25 MB, Gmail automatically adds a Google Drive link in the email instead of including it as an attachment. The person you send the file to can download it so they'll have access to it even if you remove it from Google Drive.
The value needs to be specified in KB, for example if you want to increase to 50MB, then type 51200. If you type in 0, then there is no limit to the maximum attachment size. Click OK and close the registry editor. Now you will be able to attach large files. Please note, even though you can attach any size using this hack, the actual attachment size depends on your email service provider limit.
