The right side of the heart is the pulmonary circulation pump, moving oxygen-poor blood to the lungs to unload carbon dioxide and retrieve oxygen, carrying the blood back to the left side of the heart..
Personal area network. A personal area network (PAN) is a computer network used for data transmission amongst devices such as computers, telephones, tablets and personal digital assistants. PANs can be used for communication amongst the personal devices themselves (interpersonal communication), or for connecting to a higher level network and the Internet (an uplink) where one master device takes up the role as internet router.
A pân junction. The circuit symbol is shown: the triangle corresponds to the p side. See also: pân diode and Diode Â§ Semiconductor diodes. A pân junction is a boundary or interface between two types of semiconductor material, p-type and n-type, inside a single crystal of semiconductor.he same is true of an n-doped semiconductor, but the junction between them can become depleted of charge carriers, and hence non-conductive, depending on the relative voltages of the two semiconductor regions.
