For a substance with a renal clearance of 25 ml/min, when GFR = 100 ml/min  which of the following is true?

Cardiac Output Hybrid: Cardiac output is calculated by[41](41) x [42](42). So if EDV = 150 ml and ESV = 50 ml and the heart is beating 150 times per minute what is cardiac output: [43](43: put in the number in L/min). Stroke volume is determined by 3 things: the amount of blood in the heart before contraction called: [44](44), the pressure the left ventricle has to overcome to get blood out called: [45](45), and the force of contraction called: [46](46). During exercise venous return increases drastically due to increased muscle pump this would lead to an increase in which volume:[47](47: A or B). The strength of heart contraction is controlled by the[48] (48: L, M, or N) which causes more[49](49: O, P, or Q) to flow into cardiac myocytes leading to [50] (50: R, S, or T) and a stronger contraction. This increase in contraction strength increases stroke volume by decreasing [51](51: cardiac measurement).   A. End diastolic volume E. Systolic blood pressure I. Afterload M. Parasympathetic nervous system Q. Ca++ B. End systolic volume F. Contractility J. Heart rate N. Somatic nervous system R. Stronger action potential C. Ejection fraction G. Stroke volume K. Aortic stenosis O. Na+ S. More actin/myosin interaction D. Mean arterial pressure H. Preload L. Sympathetic nervous system P. K+ T. More filling time
