Catalytic feedback
The pancreas secretes 2 hormones that affect the blood glucose level, they are insulin and glucagon. Glucagon is the hormone that raises blood glucose level. It works by changing glycogen into glucose through a process known as glycogenolysis.
The blood returns to the heart through veins.
A process known as diffusion. The plasma in your blood.
Glucose is the only fuel normally used by brain cells. Because neurons cannot store glucose, they depend on the bloodstream to deliver a constant supply blood glucose. A process called glycogenolysis can break down glycogen stored in the liver to glucose. This then travels in the blood to your brain or muscles in need of glucose.

Glucose meters process a blood sample usually taken by a small lancet pricking the skin of a finger. The blood is oxidated by glucose oxidaze and the resulting gluconulactone are counted.
Facilitated Diffusion
The blood returns to the heart through veins.
Blood sugar comes from the foods you eat. Food is broken down into glucose in the digestion process
Glucagon is a hormone created by the pancreas that signals the liver to release glucose when the blood sugar level is dangerously low by converting glycogen (glucose converted for long term "storage") into glucose in the process known as glycogenolysis. Insulin is the hormone created by the pancreas that tells the liver to convert excess glucose into glycogen when the blood sugar level is high in the process known as glycogenesis.
reabsorption
Your blood sugar will become low once you are fasting, and when that happens the alpha cells of the islets of Langerhans will allow glucogen to be release. Glucogen promotes the conversions of glycogen to glucose, which is released into the blood. As glycogen is converted to glucose in the liver the blood sugar level returns to normal.
Correct, glucose is a blood sugar.
A fasting blood glucose of 137 is a concern. A random blood glucose of 137 is not a concern.
