where the blood performs its ultimate transport function	Microscopic capillaries
the organ that keeps the blood moving through the vessels. If it loses its pumping effectiveness for even a few minutes, the individual's life is jeopardized pumps about 5 liters of blood every minute throughout life	Heart

Heart is influenced by the Autonomic Nervous System. 1 Increases the heart rate 2 Decreases the heart rate	. 1 Norepinephrine 2 Acetylcholine
Rhythmic beat of the heart depends mostly on this Pacemaker of the heart most rapidly beating part of the heart Controls heart rhythm and initiates contraction of the heart	Sinoatrial Node
Impulse of the Heart (In order)	1 Sinoatrial Node 2 Atrio-ventricular Node 3 Atrio-ventricular Bundle 4 Ventricles
1 Chronotrophic effect 2 Volume of blood ejected by the heart per beat 3 Inotropic Effect	1 Tachycardia (fast heart rate) 2 Stroke volume 3 Increased force of contraction
Volume of blood pumped in one minute; depends on the heart rate and stroke volume	Cardiac Output HR x SV
