Systolic blood pressure is recorded a. in arteries and is the minimum pressure that is recorded during ventricular relaxation. b. in both arteries and veins and is the maximum pressure recorded during diastole of the heart. c. in arteries and is the maximal pressure that is recorded during ventricular contraction. d. in veins and is the minimum pressure recorded during atrial relaxation. e. in veins and is the maximal pressure recorded during atrial contraction.

C) in arteries and is the maximal pressure that is recorded during ventricular contraction.

Explanation:

The blood pressure refers to the pressure applied on the blood vessels by the circulating blood in the vessels. The two values of the blood pressure is recorded in the blood vessels are the systolic or upper and diastolic or lower blood vessel.

The systolic pressure refers to the pressure applied by the blood on the arteries which supplies oxygenated blood from he heart to body.  The pressure of the blood however is applied by the left ventricle of the heart which pumps the blood through arteries to the body.

Therefore measuring the systolic pressure represents the pressure applied by the contraction of the left ventricle on the blood.

Thus, Option-C is the correct answer.
