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.
Please note that, even if you increase the max allowed file size from the Windows registry, it may be useless because a large file attachment will anyway be rejected by the mail server of the person receiving it. Most email servers allow between 10 and 30 Mb per incoming email. Tags: file attachment, maximum email size, Outlook 2013
