ludmilkaskok [199]

Answer:

In chronic hypertension the baroreceptors get used to high blood pressure and does not respond effeciently.

Explanation:

Hypertension is the condition when blood pressure usually remains higher than normal. The systolic higher blood pressure is considered high above from 139 (mmHg) and diastolic is considered as above from 89 (mmHg).

Most important and fast of these is baroreceptors present in blood vessels that detect the change in blood pressure and signal to brain for proper response such as dilating the blood vessels in case of high blood pressure.

In coronary hypertension the walls of blood vessels become stiffer due to several factors such as smoking, stress and ageing. The high blood pressure produces tension in the wall of artery which is detected by baroreceptor. In coronary hypertension these barorecepetors get used to higher blood pressure thus does not response to it properly. So blood pressure remains high.
