What is the core temperature?

The core temperature is the temperature of the organism in which it is to operate. It tends to refer to the temperature of the organs and parts of the body that are well insulated, unlike the skin and other surface areas that fluctuate much wildly. It differs from species to species, but always the temperature at which everything works best. When the body heats up due to external pressures, the internal mechanisms cool everything to ensure that the body works best. Similarly, when the external environment becomes cooler than the organism, the internal processes heat up.

This temperature is measured in many different ways. The simplest traditional measurement method was with a thermometer placed under the tongue and a little there. The oral temperature is notoriously unreliable; However, and is subject to any number of interference. The rectal temperature is considered much more reliable, albeit somewhat more difficult to obtain. There are also modern thermometers to be used in the ear that uses infrared lasers to determine the temperature of the tympanic membrane. Although they areFor thermometers of the ears very comfortable, many studies have found that they are fast noise and are not recommended as a method of determining fever.

The average normal temperature of the human core is approximately 98.2 f (36.8 ° C), plus or minus 1.3 ° Fahrenheit (0.7 ° C) at orally and about 1.0 ° C) higher when it is rectally accepted. People's temperatures actually fluctuate during the day, increasing when a person is more active, and fall to the lowest point in the middle of the sleep cycle. Traditionally, the average human temperature was listed as 98.6 F, which is the transmission of the previous measurement from the 19th century.

The core temperature is monitored by nerve cells throughout the body. When they detect a change in temperature from the ideal, the nerve cells in the hypothalamus of the brain react either by acceleration or by slowing down the impulses.

This means that when the body begins to cool down and the core temperature begins to drop before its ideal, the nerve cells accelerate and the bodywill start shaking. The shake generates the heat that warms the body. Blood vessels are also contractual, so less blood comes from the core and there is less heat loss. When the body discovers that it is colder, it also causes the hair to be built at the end. For mammals with lots of hair this trap air, which acts as a layer of insulation. In humans, because we have little hair left, it only expresses as goose wounds and does not help much when heating the inner body.

Fever is a brother, when the body basically changes what they think should be the core temperature. Suddenly he wants the body to be warmer than it would be normally, usually trying to expel an enemy attacker. Normal reactions still apply: shaking, reduced blood flow, etc., but now it drives the temperature for what to work.
