For my steam project I did an acrylic painting of the colon, or the large intestine. You can see how I painted the cuboidal epithelial tissue above the blood vessels with a layer of soil upon it. This soil represents bifidobacteria, which is the first layer of bacteria we feed probiotics to. Essentially, feeding the layers of healthy bacteria is necessary for a healthy gastrointestinal tract because it can prevent Irritable Bowel Syndrome. IBS causes uncomfortable symptoms such as bloating, constipation, diarrhea and cramping. I painted a garden through the colon because it is important to understand that we must eat a healthy and balanced diet to also be able to achieve this, and it cannot be done alone through probiotics. The epithelial barrier tissue, which absorbs nutrients, must yes, be healthy in the first place to do so. We must in turn feed them healthy nutrients full of balanced proteins, vegetables, fruits, and fats. If we do so our colon looks like this, happy and healthy! We then also give the barrier tissue the ability to block the entry and attacks of deadly pathogens, such as salmonella.
