Which of the following is not a mechanism that increases blood volume and therefore the venous return of blood to the heart? Cardiac output is determined by: Which artery in the arm is used to measure blood pressure? Blood pressure usually expressed as:
Understand the Problem
The questions relate to concepts in physiology and anatomy, specifically regarding blood volume regulation, cardiac output, the measurement of blood pressure, and expressions of blood pressure.
Answer
C) Atrial natriuretic peptide, C) stroke volume and heart rate, A) Brachial, C) systolic over diastolic.
The answers are: C) Atrial natriuretic peptide, C) the stroke volume and heart rate, A) Brachial, C) systolic pressure over diastolic pressure.
Answer for screen readers
The answers are: C) Atrial natriuretic peptide, C) the stroke volume and heart rate, A) Brachial, C) systolic pressure over diastolic pressure.
More Information
Atrial natriuretic peptide reduces blood volume by promoting sodium excretion. Cardiac output depends on stroke volume and heart rate. The brachial artery is traditionally used for blood pressure measurement, which is recorded as systolic over diastolic pressure.
Tips
Be careful not to confuse mechanisms that increase blood volume with those that reduce it. Ensure to understand the difference between systolic and diastolic pressures.
