Question

blood pressure multiple choice is highest when the heart relaxes. is considered high when it is above 100/70 mm hg. can be lowered by the constriction of arterioles. contributes to movement of substances from the blood into the tissues. can decrease because of atherosclerosis

Answer 1

Blood pressure is a measure of the force that blood exerts on the walls of arteries. Vasoconstriction of arterioles can help lower blood pressure.

Step-by-step explanation:

Blood pressure is a measure of the force that blood exerts on the walls of arteries. It is expressed as a double number, with the higher number representing systolic pressure when the ventricles contract and the lower number representing diastolic pressure when the ventricles relax. Normal blood pressure is generally defined as a pressure of 120/80 mm Hg or less. Vasoconstriction (narrowing) of arterioles can help lower blood pressure, and blood pressure plays a role in the movement of substances from the blood into the tissues. Blood pressure can also decrease due to a condition called atherosclerosis, which is the buildup of plaque in the arteries.
