Normal human body temperature, also known as normothermia or euthermia, depends upon the place in the body at which the measurement is made, and the time of day and level of activity of the person. Despite the popular belief, there is no single number that represents a normal or healthy temperature for all people under all circumstances using any place of measurement. Different parts of the body have different temperatures. Rectal and vaginal measurements, or measurements taken directly inside the body cavity, are typically slightly higher than oral measurements, and oral measurements are somewhat higher than skin temperature. The commonly accepted average core body temperature (taken internally) is 37.0 °C (98.6 °F). However, this is actually a 19th Century approximation by German Physician Dr. Carl Wunderlich. The Celsius value is set on an even degree, with the Fahrenheit merely being an overly-precise approximation.[1] The typical oral (under the tongue) measurement, which the cited Harvard study agrees with exactly as the true average human body temperature, is slightly cooler, at 36.8° ± 0.4°C (98.2° ± 0.7°F), and temperatures taken in other places (such as under the arm or in the ear) produce different typical numbers.[2] Although some people think of these numbers as representing the normal temperature, a wide range of temperatures has been found in healthy people.[3]

Variations in body temperature are part of the circadian rhythm (see at 4:30 and

Homeostasis Research Paper

Homeostatic Control Of Body Systems Homeostasis: Homeostasis is the function of the human body which helps it to resist change for it to maintain a normal, steady internal environment which is relatively constant. There are mainly four mechanisms which are involved in Homeostasis. These four mechanisms are the lungs, the pancreas, the kidneys and the skin. The first mechanism, the lungs, are involved in Homeostasis as they are why respiration occurs; respiration is important for many reasons, but…

An Analysis of Can Humans Hibernate? by Sheena L. Faherty Essay example

In the article “Can Humans Hibernate?” Sheena L. Faherty, a Ph.D. candidate in the Biology Department at Duke University, and a blogger, questions about humans and hibernation. She begins telling a short, but questionable event for investigators on how a teenager that flew hidden in the wheel of an airplane could have “survived the freezing temperatures and low-oxygen conditions of the unpressurized compartment” (Faherty). She points out that the most probable theory is that he went into a “state…

Physiology P 6 Homeostasis Essay

is homeostasis? Homeostasis is the control of internal conditions such as temperature, blood conditions or other variables within living organisms. The purpose of homeostasis is to provide an internal environment so that set processes can occur. Each process or reaction that occurs has a peak environment which is known as a norm. Influences such as external influence can cause departure away from this norm level and the body will correct it which is known as negative feedback. Negative feedback…

Homeostatic Organism: Negative Feedback Mechanisms

energy transfer in bodies. There are two hormones responsible in controlling concentration of glucose in the blood. Insulin and glucagon are two different hormones from the pancreas and target the liver. Insulin is secrets by beta cells while alpha cells secrets glucagon. Insulin will release and promotes conversion process of glucose into glycogen when an increased in glucose level detected. While glucagon released when glucose levels…

Thermoregulation

Adaptive advantages of Thermoregulation There are multiple adaptive advantages for a human or animal if they are able to regulate their internal temperature. In the long term, if a organism’s metabolic process can still function in changing environments, they are able to relocate in a wider range of habitats and reproduce more successfully. But the more advanced an organism's thermoregulation system, the better chance they have at surviving the changing environments as climate change become even…

enzymes is strongly affected by changes in pH and temperature. Each enzyme works best at pH 7 and temperature 370C in human body. Extremely high or low pH values generally result in complete loss of activity for most enzymes. An enzyme will denature if the pH level is too low or too high. The bonds in the enzyme break and the enzyme loses its shape and it can no longer do its task. Many enzymes are adversely affected by high temperatures. High temperature often causes permanent damage to the molecular…

internal conditions stable. An example of homeostasis is body temperature regulation in humans. Regardless of the external temperature, the core temperature of a healthy individual typically remains the same, at 98.6 degrees Fahrenheit. (Unless under extreme conditions. For example, being below freezing weather and under dressed, could cause the core temperature to decrease, so the heart would pump the blood to the most vital parts of the body, thus making the limbs vulnerable to frostbite because…

Daphnia Experiment

of the Daphnia produced rhythmic outputs to the rest of its body. This indicates that external factors have an effect on the heart rate of Daphnia. For example, in the control or room temperature test, the heart rate for that Daphnia was a normal rate, but at 5℃ the heart rate decreased a lot. The results for the control and the 5℃ water were as expected. The result of 226 bpm for the control at about 25℃ was around the same as the normal heart rate for Daphnia. The heart rate of the Daphnia was expected…
