The anterior (say: AN-teer-ee-ur) chamber is the space between the cornea and the iris. This space is filled with a special transparent fluid that nourishes the eye and keeps it healthy. What's the Lens? You absorb 20 per cent of alcohol into your bloodstream through your stomach and the rest into your bloodstream through your small intestine.There are two subsystems within the immune system, known as the innate (non-specific) immune system and the adaptive (specific) immune system. Both of these subsystems are closely linked and work together whenever a germ or harmful substance triggers an immune response. Your eyes are at work from the moment you wake up to the moment you close them to go to sleep. They take in tons of information about the world around you — shapes, colors, movements, and more. Then they send the information to your brain for processing so the brain knows what's going on outside of your body. Many people assume that sleep helps the brain rest, but our brains are actually busier while we're sleeping! When we sleep and dream, our brains carry out important functions they cannot while focusing on movement and conscious thought. They also process things we learned and emotions we felt during our waking hours, filing them away in our memories. That’s why sleep is so important to learning.

The body needs fat to thrive. All your cells are held together by a membrane of fat that regulates what comes in and out of the cells. Cells use fat as fuel, since it converts more easily into fuel than protein or sugars. Fat is also necessary to build cholesterol, hormones, and neurotransmitters. The nervous system, which consists of your brain, the spinal cord, and all the nerves throughout your body, controls movement, balance, the five senses, thought processes, and awareness. The innate immune system provides a general defense against harmful germs and substances, so it’s also called the non-specific immune system. It mostly fights using immune cells such as natural killer cells and phagocytes (“eating cells”). The main job of the innate immune system is to fight harmful substances and germs that enter the body, for instance through the skin or digestive system. The respiratory system facilitates breathing; more specifically, the intake of oxygen and expulsion of carbon dioxide. Rods and cones process the light to give you the total picture.

But it's a little more complex than that. The red color of blood is created because the iron in your hemoglobin is bound in a ring of atoms called porphyrin. This structure has a shape that makes the blood appear red. When oxygen binds to the porphyrin ring, it changes the shape, making our red blood cells appear an even more vivid shade of red.
