Blood sugar level several interacting systems, of which hormone regulation is the most important. There are two types of mutually antagonistic metabolic hormones affecting blood glucose levels: These hormones are secreted from pancreatic islets which are bundles of endocrine tissues. There are four types of pancreatic islets, alpha (A) cells, beta (B) cells, Delta (D) cells and F cells. Glucagon is secreted from alpha cells, while insulin is secreted by beta cells. Together they regulate the blood-glucose levels through negative feedback, a process where the end product of one reaction stimulates the beginning of another reaction. In blood-glucose levels, insulin lowers the concentration
Regulating Lines Regulating Lines Regulating Lines is a design concept in architecture which uses proportions of geometry in buildings giving its harmony and order. A prominent architect who espoused this concept was Le Corbusier. Regulating Lines have been used in early buildings like Notre Dame and Michaelangelo’s Capitiol etc. Le Corbusier argues from historical evidence that great architecture of the past has been guided by the use of what came to be known in English as "Regulating lines". These lines, starting at significant areas of the main volumes, could be used to rationalize the placement of features in buildings. Le Corbusier lists
