Answer:
D) Insulin
Explanation:
Insulin is an organic molecule, specifically a protein molecule, which is produced by the pancreas. It is an enzyme that regulates the level of glucose in the blood. Insulin carries out this function by converting excess glucose in the blood into a stored form called GLYCOGEN.
The glycogen, which is stored in the liver, is converted back to glucose when the need arises for glucose in the blood. Hence, INSULIN is that large organic molecule (protein) that helps to maintain glucose levels in the blood and is released from the pancreas.

Animal Circulatory Systems An efficient circulatory system has: a fluid, e.g., blood, to carry the materials to be transported; a system of vessels to distribute the blood; a pump to push the blood through the system; exchange organs to carry out exchanges between the blood and external environment, e.g., lungs and intestine to add materials to the blood; lungs and kidneys to remove materials from the blood. The most crucial demand on the circulatory system is the transport of oxygen and carbon dioxide to and from a gas exchange organ: lungs or gills and the tissues. All exchanges between blood and cells occur in the capillaries. The force of the pump that pushes blood through the arteries is dissipated as the blood flows through capillaries.
