- Which of the following is TRUE concerning blood distribution within the body? Question 22 options: Blood is distributed 50/50 through arteries and veins to equalize blood pressure At rest, the heart contains 35% of blood volume At rest, the venous system contains approximately 2/3 of the blood volume Arteries are typically empty until the heart has pumped blood into them Arterial valves allow blood to enter the heart too quicklyWhich of the following statements best describes systolic blood pressure? Systolic blood pressure depends upon the force of the heart contractions - the stronger the contractions the higher the systolic pressure will be. Systolic blood pressure depends on how tightly the cuff of the sphygmomanometer is tightened. Systolic blood pressure depends upon the resistance of the blood vessels - the greater the resistance to blood flow the higher the systolic pressure will be. Systolic blood pressure depends upon the force and frequency of the heart contractions - the stronger and more frequent the contractions the higher the systolic pressure will be.Blood is a crucial component of the cardiovascular system.
