  1. Insulin decreases blood glucose levels.
  2. Insulin increases blood glucose levels.

Rationale 1: Insulin is secreted by the pancreas when blood glucose levels are too high; therefore, it decreases blood glucose levels.
Rationale 2: Glucagon is released in order to increase blood glucose levels.
Rationale 3: Insulin is manufactured by the endocrine system, specifically the pancreas.
Rationale 4: Insulin does not play a role in fluid balance.

Global Rationale: Insulin is secreted by the pancreas when blood glucose levels are too high; therefore, it decreases blood glucose levels. Glucagon is released in order to increase blood glucose levels. Insulin is manufactured by the endocrine system, specifically the pancreas. Insulin does not play a role in fluid balance.
