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 human body regulates temperature by keeping a tight balance between heat gain and heat loss. Your temperature regulation system is more analogous to the operation of a home furnace, as opposed to the function of an air conditioner.Humans regulate heat generation and preservation to maintain internal body temperature or core temperature.our temperature regulation system is more analogous to the operation of a home furnace, as opposed to the function of an air conditioner.
