Card preview (9)
composition of blood (4)
red blood cells (Erythrocytes) white blood cells (Leucocytes) platelets plasma
cardiac output
stroke volume x heart rate
stroke volume
volume of blood pumped out of the left ventricle after a contraction
factors affecting cardiac output (3)
• gender • training status • age
cardiovascular drift (3)
• increase body temperature (lower heart rate) • decrease blood volume from sweating • stroke volume decreases as the heart rate increases
systolic
force exerted by blood on arterial walls during contraction
diastolic
force exerted by blood on arterial walls during relaxation
cardiovascular adaptations from endurance training (3)
• increased left ventricle • increased stroke volume • lower resting heart rate
