Summary:  Your immune system is the defense against bacteria. It fights bacteria before medicine does. Your immune system performs many different actions to destroy bacteria to keep you healthy. However, there are also some serious flaws in the immune system. The problem is that the white blood cells in the immune system sometimes attack red blood cells and other “good” cells thinking that they are pathogens and bacteria. Another problem is the skin is too easy penetrate. We want to reprogram the white blood cells so that they are smarter to know the difference between good and bad because sometimes your white blood cells will attack your red blood cells. We can also make it so that there are more white blood cells so that when viruses get into your body it is easier to kill the virus and so that you don’t get sick as easily or much at all. Your skin should also be thicker so that when something tries to puncture your body it is much harder. Now you make ask, what would be neede...

Summary : Skin is our largest organ. It serves as a protective barrier that prevents internal tissues from exposure to trauma, ultraviolet (UV) radiation, temperature extremes, toxins, and bacteria. Skin can be easily broken. Just falling on the ground can make you start to bleed. you've probably heard people tell you to clean a cut and but a bandage on this. This is so your insides don't get bacteria inside of them, rendering you sick in some cases. Well with our re-design, we would modify the skin so that the problem of opening a wound doesn't happen. The skin could be thicker making it harder to get a cut, as well as fighting bacteria on the skin, before it enters the body. SP1 - Asking Questions & Defining Problems: My group and I where able to find an issue with the immune system (As that was the system we wanted to redesign) by looking at which organs have the biggest effect and the problems associated with that organ. My group chose skin as our organ of ...

       The debate has been going on for decades, is it healthier to be an omnivore or a vegetarian? Well here's the answer, being an omnivore is healthier than being a vegetarian.  Throughout evolution, humans have been eating meat. Our digestive systems are well equipped to make full use of the fats, proteins and nutrients found in animal foods. Another is that you need protein. Protein is important for bone health. C onsumption of protein is associated with increased bone density in old age and a lower risk of fractures. As well as when you get rid of meat you lose key nutrients which enhance the function of the immune and nervous systems. From reading the article 7 Reasons Not to Avoid Meat by Kris Gunnars I know that throughout evolution, humans and pre-humans have been eating meat. Our digestive systems are well equipped to make full use of the fats, proteins and nutrients found in animal foods.The truth is that humans are omnivores. We function...
