Summary:
The integumentary system includes your epidermis, dermis, and hypodermis. It is the largest organ of your body. Some of it's functions are protection, prevents dehydration, produces vitamins and certain hormones. Your skin is your first line of protection against bacteria and infections. It helps your body maintaining homeostasis.Some Interesting Things That I Have Learned
In this unit, I learned a lot of things that I previously didn't even know existed. Some of those things were:- Why do goose bumps happen?
- What was responsible for the feeling aspect of our skin?
-Its and organ?
Goosebumps
When the body gets cold and needs to warm up, it sometimes results in goosebumps. Goosebumps are the result of your Arrector Pili Muscle contracting. This little movement in your dermis (second layer of skin) is there to try to produce heat and make you shiver.Sensing Touch
When we went in depth on what little things caused certain functions in our bodies, I was amazed to see that there were actually two things in our skin that allow us to feel. One being your Meisinner's corpuscle, & two being your Pacinian Corpuscle. Your Meisinner's Corpuscle senses light touches, as in someone gently brushing against you. The Pacinian corpuscle actually is responsible for deep feelings as in pain and pressure.
Organ?
I actually had no idea that your skin was considered an organ. Actually, I thought that only your heart, brain, liver, etc. were only organs. I guess its very important to the human body because the fact that it holds everything in.Cardiovascular VS Integumentary
Certain aspects of the integumentary system most definitely tie in with the cardiovascular system. For example, the veins and arteries that run all over your body also run through your skin. Your skin is actually a great and reliable thermometer for your blood vessels. The colder it gets, the deeper your blood vessels go inside your body, to keep warm. our blood loses heat to internal organs and cools. This loss alerts the nervous system to retain heat by constricting dermal blood vessels. When our body and blood temperature rises, dermal vessels dilate and sweating begins.Quick Diagram of a Good Chunk of What I Learned
