Blood sugar level In humans, glucose is the primary source of energy, and is critical for normal function, in a number of tissues, particularly the human brain which consumes approximately 60% of blood glucose in fasted, sedentary individuals. Glucose can be transported from the intestines or liver to other tissues in the body via the bloodstream. Cellular glucose uptake is primarily regulated by insulin, a hormone produced in the pancreas. Glucose levels are usually lowest in the morning, before the first meal of the day, and rise after meals for an hour or two by a few millimoles. Blood sugar levels outside the
Organ printing are some organ-specific structural elements that must be addressed for successful creation of a transplantable printed organ. The transfer of nutrients and oxygen to cells throughout a printed organ is essential for its function. In very small or thin tissues of less than a millimeter in thickness, cells can receive nutrients through diffusion. However, larger organs require the transportation of nutrients to cells deeper inside the tissue, which requires that the tissue be vascularized, and thus able to receive blood for the exchange of cargo like oxygen and cell wastes. Early organ printing techniques created solid tissues that were unable
