Biology SPMF5Chapter 3 – C&R

When the person is cold, the body temperature _________________________.

This will be detected by ________________ and send impulse to ______________.

As a result, the hypothalamus sends impulse to various _____________________.

First, skin blood vessel will undergo __________________________. This is to limit _____________________ from skin.

Second, skeletal muscles will ___________________________. This is to generate ___________________ from muscle friction.

Third, erector muscles will ________________________. This is to entrap _______________________________________ around skin.

Finally, both _______________________ and _______________________ glands will active. This is to increase _________________________________.

As a result, the body temperature _____________________ and finally returns to ___________________________.
