AB Venous  return  refers  to  the  amount  of  blood  and  blood  flow  returned  back  to  the  heart  from  veins.  The  cardiovascular  system,  consisting  of  both  systemic  and  pulmonary  circulations,  is  a  closed-loop  system,  with  the  right  ventricle  receiving  blood  from  the  systemic  circulation  and  the  left  ventricle  receiving  blood  from  the  pulmonary  circulation.  At  steady  state  conditions,  cardiac  output  (CO)  equals  venous  return.  If  CO  did  not  equal  venous  return,  then  blood  volume  would  collect  in  one  part  of  the  circulation  or  another.  Therefore,  since  CO  is  5  L/min,  venous  return  also  equals  5  L/min.
