1.2: Circulatory
One of the most important systems, this system pumps 'blood' (Thirium, also known as Blue Blood™) throughout the body and supplies 'organs' (biocomponents) with the Thirium they need to function.
Thirium 310 is a blue substance, derived from the element of Thirium. This refined mix is an important part of an android's function. Not only does Thirium act as blood for an android it serves other functions.
Thirium carries electric pulses and various data such as system statuses, identifying information (model, serial number, registered name, etc), and readies information for transfer between other androids. The electric pulses help the biocomponents to function as well as work with the android’s ‘nervous’ system to allow for movements.
Within this system, there is the Thirium pump, the Thirium Pump Regulator, Thirium, and tubing all on the interior of an android, as well as fine Thirium vessels found in the interior as well as several exterior locations that help with the artificial skin.
Parts of the Circulatory System:
- Thirium Pump
The android heart. Sits in the upper left-center of the chest. Located almost in the same place as a human's heart and its appearance looks rather the same as well. It looks like a metal human heart.
The Thirium Pump shares a very similar appearance to that of a human heart but lacks several major features that a human heart holds. It varies in color from a blue to a red or gray color.
A healthy Thirium Pump glows a bright to light blue, the same tint blue as Thirium. When damaged, not optimally running, or in androids that are in the process of shutting down the pump will beat with a bright red glow. As the android shuts down or Thirium supply is lost to the bicomponent the glow fades until the heart darkens.
- Thirium Pump Regulator
Located above the navel and below the sternum, the Thirium Pump Regulator, Regulates the heartbeat by regulating how fast the Thirium Pump beats. An android's heart should beat at around 50 to 90 beats per minute.
The closer to 50 the better. Below 50 bpm might not be an issue and can fall below 50 when they are in stand by, sleep or low power modes. However serious problems can occur or be at fault for the low bpm. The lower the bpm the more danger the android is in with the potential for overheating or even shut down.
Higher than 90 bpm and problems can also occur. An android could overheat, go into a state that equivalent to cardiac arrest and even shut down. The thirium pump regulator is easily removed, and can easily be fixed or replaced if needed. But without it, the android will shut down within minutes.
- Thirium
The blood of an android. Often referred to as blue blood due to its color and function. Blue blood is the trademarked name given to Thirium by CyberLife.
Thirium that pumps through an android body is specifically Thirium 310.
Thirium helps biocomponents function, helps regulate internal temperatures (along with the thermal regulator), supplies energy, and carries data.
Used Thirium carries the data of the android it pumped through. Within this data is an android's model and serial numbers.
Healthy Thirium levels in adult-sized models should be around four (4) to five (5) liters, very similar to that of human blood. Smaller androids require less Thirium and their optimal levels should range between two (2) to three (3) liters. This is why even minor damage can be fatal to child units. Thirium levels can fall when an android becomes damaged. Thirium levels can be replenished orally or intravenously.
Androids can lose some thirium without being in danger, and sometimes they naturally lose small amounts. But when their levels fall below a certain amount the android will automatically shut down.
Thirium pressure is the pressure at which the blood pumps through the body. A healthy android's blood pressure is the same as human blood pressure, which is 120/70 with damage arising with lower or higher rates.
- Tubing
Androids are made with various tubes and wires that transport thirium and data. There are tubes are throughout the body, under the outer shell, but some are closer to the surface.
The circulatory system is made up of tubing of varying sizes that are sometimes referred to as lines, these tubes carry Thirium throughout the body to biocomponents much like the veins and arteries of a human's body. Veins carry thirium from biocomponents and arteries carry thirium to biocomponents.
Tubing and lines are 'softer' and most are very flexible. Tubes can be made up of several types of material. The makeup of veins and arteries can vary by model or even within a single android body. The specific make up does not matter, as long as the size and flexibility are proper to what is needed.
An android's body has several main arteries and many veins and arteries in a complex network. Many of these connect biocomponents to one another so that thirium and data can be carried and circulated throughout the body. Some of these are similar to a human's anatomy while many others are original to an android's complex make up.
Notable lines and tubes:
- Jugular Tubes
Android bodies much like a human contain a jugular vein. The location closely mimics a human's. This larger vein runs along the neck and if served will allow the android to quickly bleed out, causing a swift shut down. There are two jugular veins. Exterior and interior. The exterior vein is closer to the surface, just under the frame. The interior vein is buried deeper into the body.
- Femoral Lines and Tubes
Once more just like humans, androids have femoral veins and arteries in their legs. While the location is similar the appearance is unique to androids. These larger veins and arteries carry a large Thirium supply to and from the legs, feet, and biocomponents in the lower half of the body.
- Carotid Line
Major Thirium vessels that carry blood to the processor, neck, and face. There are two lines on either side of the neck. One of the few lines that are similar to a human's anatomy with its location, appearance, and function.
- Coronary Tubes
The lines that supply the Thirium Pump with its Thirium supply. While it shares a name to an artery found in the human body and it's even in a similar location this specific set of tubes isn't like human anatomy at all. The difference is easily distinguished visually.
