Insulin
This
is a hormone made in the pancreas (see also digestive
system for location of pancreas in the human body).
Insulin helps regulate the sugar in the blood
from getting too high (a condition known as hyperglycemia), or too
low (a condition known as hypoglycemia). People who require insulin
injections are usually those with type 1 diabetes who cannot make
insulin due to certain non-functional cells in the pancreas.
