What we did!

1) Quiz on the Eye, Ear, and Brain and people did not do good.
2) Initial lesson on the endocrine system.

3) Mr. Challoner Asked us about what we knew and didn't know about the ES. 

(we didn't know either)

4) We read some articles on stem cell research

5) We learned the main organs of the ES ( I saw a gross picture of a goiter in the textbook)

Thoughts and/or opinions

I felt that the endocrine system was going to be more challenging 'rotha' than as straight forward as the Nervous system. I thought that it was funny how daniel didn't know what he didn't know. I found it interesting to learn that when adrenaline is released from the adrenal gland it is to maintain homeostasis although when it is pumping you seem to be at a heightened alertness and focus.  It makes me wonder what exactly happens to your body when adrenaline is released into the blood stream? 

Bed, Bath and Beyond

Adrenaline looks like that. no joke. go get a microscope. i'm super seriall.

According to wikipedia, http://en.wikipedia.org/wiki/Epinephrine, Epinephrine (Adrenaline) is triggered as a "fight or flight" response from ATCH. It causes a wackload of stuff meaning there are a lot of cells with receptors to this hormone. It boosts the supply of oxygen and glucose in the brain and muscles but suppresses non-emergency systems like the digestive system. It causes the breakdown of fats and glycogen to produce more glucose for even more cellular respiration in the brain and muscles. Your pupils dilate and gives your skeletal muscles more blood flow. A downside of this is that it takes away from your immune system to allow you to fight or flight. most bad ass blog ever.
