Place the tri-tip on the cool side of the grill, with the thickest part of the steak facing the hot side of the grill, and cook with the lid closed. Turn the steak occasionally, about every 20 minutes, until it reaches 110Â° (43Â°C) in the center of the thickest part.
Ligaments. Ligaments are organs that connect bone-to-bone in the skeletal system. They are fibrous tissues that provide stability to joints throughout the body during rest and active movement.
The spleen and the thymus are also lymphoid organs of the immune system. The tonsils are lymphoid organs that are also associated with the digestive system. Lymphoid tissues contain lymphocytes, and also contain other types of cells for support.
