4. Avascularity. Epithelial cells DO NOT have ANY blood vessels but they are inverted (meaning they have a nerve supply) aka they have nerves-the epithelial tissues get their oxygen and nutrients from the blood vessels with in the connective tissue that underlies the epithelium.
Prepare the grill for direct grilling at 500ÂºF. once hot, clean the grill surface with a sturdy grill brush. For filets that are 1-inch thick, we grill the salmon for a total of about 8 minutes over a 500ÂºF fire. This should result in fish that is cooked medium to medium-well. Place each filet on the grill grate directly over the fire with the skin-side up. After about 5 minutes, the edges of the meat should begin to pull away from the grill. The salmon will release from the grill when it is ready to turn over. A few exploratory lifts at the edges should tell you whether or not it is ready.
In a small bowl, stir together the oil, soy sauce, Worcestershire sauce, lemon juice, ginger, honey, basil and shallots. Pour over the salmon and let it marinate while you preheat the grill, about 20 minutes. Preheat a grill for medium-low heat. Slide the foil with the salmon off of the cookie sheet and onto the grill. Cover with the lid and grill the fillet for  10 minutes per inch of thickness, about 20 minutes. Salmon should be able to flake with a fork, but not be too dry.
