Task # 1.1.1Unit 1: Homeostasis maestro
Key Concept: SystemsGlobal context: Identities and Relationships
Statement of Inquiry: Homeostasis in human beings’ bodies is achieved through the interaction between different body systems to keep the body’s balanced conditions. Although there are crucial relationships between all body systems to achieve this goal, their separate identities and functions are so distinct.

Factors Affecting Human body temperature

The normal body temperature has long been thought to be 37 degrees Celsius, but there are several factors that affect body temperature .Normal body temperature varies by person and can also increase or decrease as a person ages, environmental  changes, changes in diet as well as medication. Temperature readings can also vary slightly based on the method of temperature reading and the time of day that the person’s temperature is measured .

Your task is:
