- Homeostasis
- Osmoregulation
- Affects the kidney and the brain.
- Thermoregulation
- Maintaining a body temperature of 37degrees in the body
- Controlled by the hypothalamus
- Recieves info from nerve endings in dermis.
- Hypothalamus causes you to sweat if the body temp is over 37degrees
- It also increase the blood flow closer to the face so that there is more heat lose.
- If the body temp is below 37 degrees the blood flow near the surface of the skin is reduced.
- This is called Vasoconstriction.
- This is called vasodilation.
- If the body temp is below 37 degrees the blood flow near the surface of the skin is reduced.
- It also increase the blood flow closer to the face so that there is more heat lose.
- Controlled by the hypothalamus
- This is an example of negative feedback.
- This is where something will change and mechanisms work to change it back in the other direction
- Maintaining a body temperature of 37degrees in the body
- Keeping the internal environment stable.
