Secretion from the salivary glands is driven by osmosis following the establishment of osmotic gradients between the lumen, the cell and the interstitium by active ion transport.
The major pathway into saliva for most steroid hormones and other small, neutral molecules is by passive diffusion. The salivary glands are surrounded by dense beds of capillaries, and many blood components pass easily through the capillary walls, bathing the saliva glands.

Answer:
D
Explanation:
A hypotonic solution means it is less concentrated in relations to the other solution – in this case the patient’s cells. The electrolytes that balance osmotic pressure in the body are sodium, potassium, chlorides, calcium, and etcetera. The IV needs to have less electrolytes so that when the IV is injected into the patient’s blood the water can move into the cells by osmosis. Osmosis continues until the cell cytoplasm is in osmotic equilibrium with the blood. It is imporant, therefore, to have the right electrolyte balance in the IV solution otherwise the cell will over-hydrate and begin lysing – especially if the kidneys of the patient do not rid excess water fast enough.
