Sympathetic nervous system activation constricts arteries found within the salivary glands

Explanation:

The ANS controls the involuntary contraction of the heart cardiac muscles, glands, intestine, the peripheral resistance of vascular systems, and the rate of pumping of the blood by the heart.

Thus, the ANS system during stressful conditions increases the blood pressure, heart rate, constrict blood vessels in glands and intestine and dilate the pupils, in anticipation for fight or flight.
