Homeostasis In Action

For our first project in this class, we took the temperature of both Mikaella and Desi, before doing any activities, with a temperature probe at our forearms. Mikaella started off with the temperature of 87.7 and Desi did with a temperature of 78.1. Then, Mikaella began to try to rise her temperature by exercising around the room such as jogging, push-ups and jumping jacks.  Desi iced her forearm. They both waited out for 2 minutes continuing the activities then took the temperature of there forearms again. This time Mikaella's temperature was 89.1 and Desi was 63.9. Mikaella and Desi continued on with our activities for another 3 minutes and once again took there temperatures again. Mikaella came in a whopping 90.1 while Desi actually rose a little to 64.8. Finally, we waiting out for 5 minutes going through the relaxation period. When we finally took our last temperatures Mikaella's was 88 even, and Desi was 69.1. In the beginning we all had a hypotenuse that there bodies would respond with homeostasis, and we were correct. While going through the relaxation period our bodies tried to regain order, Mikaella by sweating, and Desi by shaking. It was a pretty neat experiment to do. 

Tissue

We recently did a lab on tissues. There are different types of tissue and different ways you can arrange them. Here is a video that shows you what the types of Epithelial tissues look like.http://www.youtube.com/watch?v=7z2vYr5YjD8. Stratified Columnar

As you can see all the tissue look different and they all act different to. Us doing it as a class and doing pictures of ourselves made it a little easier to understand what each tissue does and how it looks in human form. In these videos that i found show you what they look like inside a human body.

Homeostasis

Homeostasis involves the ventral cavity. The ventral cavity is in the front of the body. It is divided into three parts the contain many of the body organs that maintain Homeostasis. The prefix home/o means constant and suffix -stasis means control. In this body region our organs have to be under control. If there not our body will not function properly. I say mainly the heart and lungs need the most control out of everything else. If we can keep that under control we have maintain homeostasis.

Homeostasis, an event occurring everyday for me. I practice softball everyday five times out of the week. I move my arms a lot just as much as i run. Running makes me hot and tired especially in that hot sun. I have to take a lot of water to stay hydrated and make sure that my body maintains control in the heat. Sometimes i sweat a whole lot more then I usually do and I started getting more thirsty then usual. When its really hot outside my body starts getting weak and not wanting to do anything. That tells me that I'm not keeping myself hydrated enough and not maintaining control of my surroundings.
