As your skeletal muscles contract during physical activity, more blood is returned to the heart. which variable would be affected and what would be the outcome of this action?

Answer :

A greater cardiac output would arise from an increase in preload.

What is cardiac output?

  • Cardiac output, which is calculated as the sum of stroke volume and heart rate and expressed in liters per minute.
  • The most typical definition of HR is how many times it beats in a minute.
  • SV is the amount of blood expelled during each heartbeat or ventricular contraction.
  • Cardiac output, which is determined by the heart's pace, contractility, preload, and afterload, is the volume of blood it can pump in a minute.
  • When evaluating cardiac output values, it's crucial to comprehend how each of these four components applies and how it relates to everyday life.
  • When a person is at rest, a healthy heart with a normal cardiac output pumps 5 to 6 litres of blood every minute.
  • The volume of blood that the heart circulates across the body in a minute.
  • The stroke volume refers to the volume of blood that the left ventricle of the heart pumps during a single contraction.
  • The cardiac output is determined by the heart rate and stroke volume.
