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.
For example, sweat glands, tear glands, etc. Endocrine glands are those which are richly supplied with blood vessels and pour their secretions directly into the blood vessels. The secretions reach their target through blood. These glands are called the ductless glands as they do not have ducts. For example, thyroid, adrenal, etc.
