What is Life?
It seems as though the lines between living and non-living are quickly going to be blurred with the advent of new technologies. This year we will be focusing on the traditional eight categories which qualifies something as living. The point of today was to show the fallibility of Science, and how some of the tenets we accept as everyday truths, are far more complex than we give them credit for.
If you found today's class interesting I recommend checking out the documentary "The Transcendent Man" by Ray Kurzweil. It's about one's mans journey to live long enough to see the technological singularity.
And remember, you are what you eat! and get enough sleep!

Homeostasis
Our bodies have an amazing ability to maintain it's internal environment. Some of the various things regulated are nutrient balance, temperature, water balance, waste buildup, and pH balance. Maintaining "balance" is essential for the functioning of all of our body systems.
Speaking of body systems, for the rest of the term we are going to be looking at the interaction between groups of cells (tissues), how these tissues interact (organs), and how these organs interact (organ systems), all through the lens of homeostasis.

The Cell
We spent today talking about about the unseen parts of living systems, so I figured I would honour something a bit bigger. The ostrich egg yolk is the largest single cell on our planet. That's right, the yolk of the eggs you buy is a single cell !!!!
The below video is an excellent animation of the inner working of the cell. The organelles and functions we have been talking about come to life. Don't worry if you don't understand what's going on in certain parts, it goes into more detail than we need.

Membrane and Transport
The lipid bilayer which encloses all of our cells has very important characteristics, essential for life, due to the amphiphatic nature of phospholipids, and the various proteins, carbohydrates, and cholesterol molecules inserted within it. Understanding how the selectively permeable membrane transports different substances across it is essential to understanding many of the bodies functions. When we talk about the immune system, we will revisit cell membranes and the factors that allow cells to communicate with each other.

Cellular Respiration
When your parents would bug you as kids and say something along the lines of "go outside and burn some energy", little did they know but they were accurately describing the process of cellular respiration!!!
Cellular respiration is effectively the "burning" of glucose in our bodies. Glucose and oxygen react to form carbon dioxide, water, and energy as products. Our body doesn't use fire, but instead a complex series of enzymatic reactions with the end goal of creating high energy molecules.
