How does the human body compare to an electric circuit?

Answer 1

Electrical wires transmit electrical currents (electrons) along the wire and are encased in a insulated jacket that keeps the wires from short circuiting with neighboring wires so the electrical current can travel quickly and efficiently along the wire. Nerves resemble these wires in that the axons of the nerve fibers are similar looking as they are enclosed in a myelinated sheath. Nuerons do not transmit electrical currents, but rather they transmit charged ions.

http://en.wikipedia.org/wiki/Neuron

The neuron's place as the primary functional unit of the nervous system was first recognized in the early 20th century through the work of the Spanish anatomist Santiago Ramón y Cajal.[8] Cajal proposed that neurons were discrete cells that communicated with each other via specialized junctions, or spaces, between cells.[8] This became known as the neuron doctrine, one of the central tenets of modern neuroscience.[8] To observe the structure of individual neurons, Cajal used a silver staining method developed by his rival, Camillo Golgi.[8] The Golgi stain is an extremely useful method for neuroanatomical investigations because, for reasons unknown, it stains a very small percentage of cells in a tissue, so one is able to see the complete micro structure of individual neurons without much overlap from other cells in the densely packed brain.[9]

http://en.wikipedia.org/wiki/Structured_cabling

Structured cabling is building or campus telecommunications cabling infrastructure that consists of a number of standardized smaller elements (hence structured) called subsystems. Structured cabling falls into six subsystems: * Entrance Facilities are where the building interfaces with the outside world. * Equipment Rooms host equipment which serve the users inside the building. * Telecommunications Rooms house telecommunication equipment which connect the backbone and the horizontal cabling subsystems. * Backbone Cabling connect between the entrance facilities, equipment rooms and telecommunications rooms. * Horizontal Cablingconnect telecommunications rooms to individual outlets on the floor. * Work-Area Components connect end-user equipment to outlets of the horizontal cabling system. Structured cabling design and installation is governed by a set of standards that specify wiring data centers, offices, and apartment buildings for data or voice communications, using category 5 (CAT 5E) or category 6 cable (CAT 6) and modular sockets. These standards define how to lay the cabling in a star formation, such that all outlets terminate at a central patch panel (which is normally 19 inch rack-mounted), from where it can be determined exactly how these connections will be used. Each outlet can be 'patched' into a data network switch (normally also rack mounted alongside), or patched into a 'telecoms patch panel' which forms a bridge into a private branch exchange (PBX) telephone system, thus making the connection a voice port. Lines patched as data ports into a network switch require simple straight-through patch cables at the other end to connect a computer. Voice patches to PBXs in most countries require an adapter at the remote end to translate the configuration on 8P8C modular connectors into the local standard telephone wall socket. No adapter is needed in the U.S. as the 6P6C plug used with RJ11 telephone connections is physically compatible with the larger 8P8C ("RJ45") socket and the wiring of the 8P8C is compatible with RJ11. In the UK, an adapter must be present at the remote end as the 6-pin BT socket is physically incompatible with 8P8C. It is common to color code patch panel cables to identify the type of connection, though structured cabling standards do not require it, except in the demarcation wall field. Cabling standards demand that all eight connectors in Cat5/5e/6 cable are connected, resisting the temptation to 'double-up' or use one cable for both voice and data.

Answer 3

The brain in a human body would refer to a battery in a circuit. The veins in a human body could maybe the wire of a circuit. The blood could be the current flowing through the circuit or the body.

Answer 4

The human body can be compared to an electric circuit in that it transmits electrical signals through the nervous system, similar to the flow of electrons in a circuit. The nervous system acts like wiring, carrying information through the body to control functions and movements. Just like how a circuit can short-circuit or be disrupted, disruptions in the body's electrical signals can lead to various health issues or conditions.

Answer 5

Both nerve cells and telephone wires send signals through them.
