Temp files are usually files left over from a setup. Sometimes they get cleaned up, but yours should never have been allowed to get to large. Do a search for .tmp files on the system. Select them all> Delete. The only exception is if you have recently in last day or two installed new software. If so, that file should be allowed to remain for up to a week.
The pituitary gland is the smallest endocrine gland in the human body.
Glands are of two types. Endocrine glands do not have a duct system and are called ductless glands. These glands release hormones directly into the blood or lymph. Exocrine glands such as the sudoriferous (sweat) glands contain ducts. Ducts are tubes leading from a gland to its target organ.
