what is regulated by these small glands (highlighted in blue)?
answer:

Explanation:

Analyze the first question

The first question states: "Food molecules must dissolve in saliva to stimulate receptors."

• Gustatory (taste) receptors are chemoreceptors located on the tongue and oral cavity.
• For chemicals (tastants) to bind to these chemoreceptors, they must be in aqueous solution.
• Saliva acts as the solvent to dissolve these molecules, allowing them to enter taste pores and interact with receptor cells.
• Therefore, the statement is True.

Analyze the second question

The second question asks: "What is regulated by these small glands (highlighted in blue)?"

• The image shows the posterior view of the thyroid gland situated on the trachea.
• Four small, oval-shaped glands are highlighted on the posterior surface of the thyroid lobes.
• These are the parathyroid glands.
• The parathyroid glands secrete parathyroid hormone (PTH), which is the primary regulator of blood calcium levels (calcium homeostasis).
