The organ system which participates in the transportation of substances through blood is called the circulatory system. The muscular organ located in the chest region slightly left of the breastbone is the heart. It pumps the deoxygenated blood to the lungs and oxygenated blood to all parts of the body.

The force of blood acting against the walls of the arteries is called blood pressure. Blood pressure can be measured by an instrument referred to as a sphygmomanometer or digital blood pressure monitor.

Therefore, blood pressure is not measured using pulse.

Thus, the given option is false.

Each cardiac cycle ejects a certain amount of blood from the ventricle, and the amount of blood is called stroke volume. It is measured by a pulmonary artery catheter.

Therefore, stroke volume cannot be measured with the help of a pulse.

Thus, the given option is false.

The total blood volume pumped by the heart each minute is denoted as cardiac output. Multiplication of stroke volume and heart rate gives cardiac output.

Therefore, a pulse is not the direct measure of cardiac output.

Thus, the given option is false.

Heartbeats per minute can be referred to as heart rate. The beatings are felt in specific regions of the body, such as the wrist, side of the neck, behind the knees, and many other places. 60 to 100 beats per minute refers to the standard heart rate for adults.

Therefore, heart rate is directly measured by examining the pulse.

Thus, the given option is true.
