The rhythmic expansion and recoil of an arterial wall can be felt as a:

Blood pressure is most commonly measured in the brachial artery of the arm using a blood pressure cuff, also called a(n)

• electrocardiogram

• echocardiogram

• tonometer

• sphygmomanometer

• arm

Select all that apply.

Return of venous blood is normally dependent on which three factors?

• white blood cell count

• respiratory pump

• skeletal muscle pump

• valves in veins

• arterial blood pressure

Select all that apply.

If a person stands rigidly for a long period of time, they are likely to faint because (select all correct answers)

• poor venous return deprives the brain of oxygen.

• lack of muscle contraction allows blood to collect in the limbs.

• the respiratory pump no longer functions.

• the liver becomes enlarged and ceases to function.
