Which statement about blood pressure is true?
The top number of blood pressure reading represents the pressure exerted on the vessels when the heart is relaxing
Blood pressure can be measured directly with an EKG
A blood pressure reading of 160/100 is considered a healthy blood pressure
Factors that can increase blood pressure include stress, a high salt diet, and cholesterol buildup in the blood vessels
Both the respiratory system and circulatory system are necessary for the delivery of oxygen to body tissues. Which statement correctly explains how these two systems work together?
