A distinct, extended plateau occurs in the action potential in cardiac muscle cells, producing a refractory period of ________ milliseconds. where is the mitral/bicuspid valve located? what is the difference between cardiovascular and circulatory system? T/F: The heart separates the pulmonary and systemic circulations and ensures better oxygenation of the blood flowing to the tissues, T/F: The valves of the heart allow blood to flow in different directions through the heart based upon the pressure differences from the pulmonary and systemic circulations, T/F: The rate and force of heart contractions change to meet the metabolic needs of the tissues which can vary based on different conditions. Distinguish between flow rate and velocity of flow. which of the following is NOT true for ventricular systole, T/F: the ventricles begin to fill during ventricular diastole, T/F: atrial contraction accounts for most of the ventricular filling, During which event of the cardiac cycle does aortic pressure reach its maximun, During which event of the cardiac cycle does the atria both relax and contract, During which event of the cardiac cycle do the atria and ventricles relax, T/F: the audible heart sounds are caused by the contraction of the atria ventricles, T/F: the P wave of the ECG coincides with ventricular filling. Superior Vena Cava 2. 21. New World- Old wor. Step 1 involves the superior vena cava (SVC) and inferior vena cava (IVC). Cardiac output is determined by the rate at white the heart beats out blood and by the amount of blood the heart pushes out. These ventricles pump blood from the heart to the body. This is because it needs to pump blood to most of the body while the right ventricle fills only the lungs. Throughout most of this period, blood is passively flowing from the left atrium (LA) and right atrium (RA) into the left ventricle (LV) and right ventricle (RV), respectively (see figure at right). As an artery, it contains thicker walls than veins because it has to withstand the tough pumping blood pressure of the heart. During systole, the oxygenated blood from the left ventricle travels through the aortic valve and enters the aorta. The oxygenated blood will then travel from the lungs to the left atrium via the pulmonary veins. Because of this explanation l now understand the circulatory system better. The left ventricle is larger and stronger than the right. 2. Ventricular ejection 4. 2003-2023 Chegg Inc. All rights reserved. Give a definition for the unused terms. 12.
