, Temperature: Normal range 35.8 - 37.5 (AFEBRILE)
- cellular metabolism requires a core temperature of 37.2 °C
- normal body temp is known as normothermia
Heat production: - primary source = cellular metabolism
- produced as a by-product of cellular activities.
- hormones, muscle movement and exercise increase temperature
Heat loss: - Skin is the primary site of heat loss from the body
- skin is the largest organ
- blood vessels in the skin bring heat to the skin's surface
- surface heat escapes via the process of radiation, convection, evaporation, or
conduction
Body temperature regulation: - Core body temperature is maintained within a constant range by the
thermoregulatory centre in the hypothalamus
- The thermoregulatory centre helps to keep the body within acceptable
temperature ranges regardless of the environmental conditions
- If there is an issue in the hypothalamus of the brain, then there can be
problems with someone being able to control their own body temperature
Core receptors: Responsible for sensing internal body temperature
Skin receptors: - Detect external changes in temperature
- Send information to the hypothalamus
- Sends a message to all different body systems that we need to do something
to maintain a stable internal body temperature
Factors affecting the body temperature: Age, exercise, hormone level, circadian rhythm, stress, environment, and
temperature alterations
Circadian rhythm: Temperature is usually 0.6c lower in the morning that late afternoon and
evening
Age and gender: - The very young, the old and the infirm are more sensitive to temperature
changes in the environment
- During the menstruation cycle, progesterone secretion occurs with ovulation
- increases temperature 0.15 - 0.45 °C
