Select all of the factors that would help meet this demand. 2 Blood that nourishes the heart wall is provided by the right and left __________. 3 Left atrium 4 Select all of the correct statements regarding the size, location, and orientation of the heart. 5 Select the correct statement regarding blood pressure. 6 Select all of the factors that increase peripheral resistance. 7 Which of the following occurs during the ventricular systole phase of the cardiac cycle? 8 At the arterial end of a capillary, blood pressure is __________ than osmotic pressure, and fluid flows __________ the capillary. 9 Starting with the pacemaker, impulses pass through the components of the intrinsic conduction system in which order? 10 What connects anterior & posterior brain blood supplies? 11 Which vessel receives blood directly from the left ventricle? 12 Select all of the ways that arteries and veins differ structurally. 13 Which of the following factors would cause an increase in the heart rate? 14 Which heart chamber has the thickest wall? 15 Select all of the veins that ultimately drain into the inferior vena cava. 16 Right ventricle 17 In fetal circulation, the __________ connects the pulmonary trunk to the aorta, allowing blood to bypass the nonfunctional fetal lungs. 18 The first heart sound (lub) results from closing the __________ valves. 19 cardiac output 20 Right ventricle 21 Right atrium 22 Select all of the blood vessels that transport oxygen-rich blood. 23 Which of the following describes the umbilical vein? 24 Left ventricle 25 Left atrium 26 The layer of the heart that actually contracts is the 27 The tiny mass of cells that forms the pacemaker of the heart is called the __________. 28 Select all of the true statements regarding arteries. 29 Right atrium 30 Left ventricle Increased stroke volume Increased heart rate Aortic semilunar valve The pressure in the ventricles is higher than the pressure in the aorta and pulmonary trunk. Sinoatrial (SA) node, atrioventricular (AV) node, atrioventricular (AV) bundle, Purkinje fibers Aorta cardiac output Receives oxygen-rich blood from the lungs The heart is approximately the same size as a person's fist. The heart is located between the lungs within the mediastinum of the thoracic cavity. tricuspid and biscuspid (mitral) Pulmonary veins Aorta Epinephrine Exercise Circle of Willis The tunica media is thicker in arteries compared to veins. Veins have larger lumens than arteries. more; out of Left ventricle Great saphenous veins Hepatic veins Common iliac veins sinoatrial (SA) node Receives oxygen-poor blood from the body Transports oxygen-rich blood from the placenta to the fetus coronary arteries The systolic blood pressure corresponds to the pressure generated in an artery at the peak of ventricular contraction. Pulmonary semilunar valve Biscuspid (mitral) valve ductus arteriosus Arteries transport blood away from the heart to the capillaries. Smooth muscle in the tunica media enables arteries to change vessel diameter. Pumps oxygen-poor blood to the lungs myocardium Pumps oxygen-rich blood to the body Vasoconstriction Increased blood viscosity Atherosclerosis Tricuspid valve 1 Which electrical event does the T wave of an electrocardiogram (ECG) represent? Ventricular repolarization
