Channels found in cells in the walls of the carotid artery and the aorta respond to stretch. These channels are described as:.a. mechanically gated. b. voltage-gated. c. chemically gated. d. open or leak.

Channels found in cells in the wall of the carotid artery and the aorta response to stretch.

These channel is known as voltage gated channel.

Explanation:

Voltage gated channels are trans membrane protein that produce ion channel which is activated by change in the electrical potential.

Baroreflex are called homeostatic system of body as they helps to maintain homeostasis and the receptors are present in carotid artery and aorta which maintain the change in blood pressure.

These stretch receptors are respond to the pressure that is  generated by blood vessels.

When the blood pressure decreases,the  activity of baroreflex also decreases.

correct answer is a. and d.
