Chapter 11 The Cardiovascular System Periods of the Cardiac Cycle - Ventricular filling period (VFP) - Isovolumetric contraction period (ICP) - Ventricular ejection period (VEP) - Isovolumetric relaxation period (IRP) Copyright © 2014 Wolters Kluwer Health | Lippincott Williams & Wilkins

Chapter 11 The Cardiovascular System 6. Stroke Volume - amount of blood ejected from the ventricles with each beat of the heart SV = LVEDV - LVESV EF = (SV/LVEDV) 100 7. Cardiac Output - the amount of blood pumped per unit of time, in liters per minute • Q = SV HR Copyright © 2014 Wolters Kluwer Health | Lippincott Williams & Wilkins

Chapter 11 The Cardiovascular System 2. Arterioles Resistance vessels - another name for arterioles due to their ability to vasodilate and vasoconstrict; changing diameter allows them to control the flow of blood Copyright © 2014 Wolters Kluwer Health | Lippincott Williams & Wilkins

Chapter 11 The Cardiovascular System 4. Venules 5. Veins Capacitance vessels - another name for veins, owing to their distensibility, which enables them to pool large volumes of blood and become reservoirs for blood Copyright © 2014 Wolters Kluwer Health | Lippincott Williams & Wilkins
