RESPIRATORY SYSTEM A complete‚ schematic view of the human respiratory system with their parts and functions. Latin: systema respiratorium The respiratory system (or ventilatory system) is a biological system consisting of specific organs and structures used for the process of respiration in an organism. The respiratory system is involved in the intake and exchange of oxygen and carbon dioxide between an organism and the environment. The primary function of the respiratory system is to

and buried cables. Laser communications systems can be easily deployed since they are inexpensive‚ small‚ low power and do not require any radio interference studies. The carrier used for the transmission signal is typically generated by a laser diode. Two parallel beams are needed‚ one for transmission and one for reception. INTRUDUCTION: Laser Communication is one of the emerging area of wireless communication system. Due to its low noise ratio makes its one of the well suited communication

When a circuit is driven with direct current (DC)‚ there is no distinction between impedance and resistance; the latter can be thought of as impedance with zero phase angles.
