Vitamin B 12 deficiency anemia is more common in individuals of northern European descent. The condition is caused by one of the following: Vitamin B 12 deficiency caused by a lack of intrinsic factor in gastric (stomach) secretions--intrinsic factor is necessary for absorption of vitamin B 12.This type of B 12 deficiency anemia is technically pernicious anemia.itamin B 12 deficiency anemia is more common in individuals of northern European descent.

The body takes a very active role in temperature regulation. The temperature of the body is regulated by neural feedback mechanisms which operate primarily through the hypothalmus. The hypothalmus contains not only the control mechanisms, but also the key temperature sensors.
The hypothalamus of the brain works as the thermostat for temperature control inside the body. Throughout your body are temperature receptors that send feedback to the hypothalamus.If the hypothalamus receives indication that the body is either too hot or too cold, the brain will signal the body to react.For example, if you are outside on a hot day, temperature receptors on your skin will signal the heat to your hypothalamus which responds accordingly.hermoregulation. The body regulates its temperature by means of convection, conduction and evaporation. Convection is the change in temperature due to the movement of air or water over the skin, for example, a breeze while you are running.
