Blood Pressure

Question 1

what is blood pressure?

Answer 1

Blood pressure is the force of your blood pushing against the walls of your arteries as your heart pumps it around your body. It’s measured with two numbers:

Systolic pressure This is the pressure when your heart beats and pumps blood.
Diastolic pressure This is the pressure when your heart is resting between beats.

Question 2

How is blood pressure normally controlled in health?

Answer 2

Short term:

The baroreceptors in the carotid artery sense changes in blood pressure.
If the BP Drops, the sympathetic nervous system increases pulse rate and vasoconstriction increases BP.
If BP increases, the Parasympathetic nervous system decreases pulse rates, and vasodilate takes place to decrease BP
