A clinician is investigating endocrine and homeostatic disorders in patients.

Draw one straight line from each physiological condition to its primary underlying mechanism.

Physiological Condition

• Diabetes mellitus
• Diabetes insipidus

Primary Underlying Mechanism

• Inability of the kidneys to reabsorb water due to a lack of ADH secretion or response
• Failure of the proximal convoluted tubule to reabsorb urea
• Inability of body cells to take up glucose due to lack of insulin secretion or response
• Excessive filtration of plasma proteins through the basement membrane of the Bowman's capsule
• Hyper-osmotic gradient established solely by the active transport of water in the descending limb
