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.
Endocrine glands, e.g., the thyroid gland, are ductless glands that secrete macromolecules, called hormones, directly into the bloodstream, and such glands are richly supplied by blood capillaries. The endocrine glands include the adrenals, the parathyroids, the pineal, the pituitary, and the thyroid.
