SCIENCE TEAS TEST 6 1) Pulmonary artery transports deoxygenated blood pumped from the right ventricle of the heart to lungs while Pulmonary veins delivers oxygenated blood from lungs to left atrium. 1) This is the mass of tissue from the sternum to the vertebral column between the lungs. 2) this is the layer that protects the heart. 3) to which side of the body is the apex pointed? 4) which of the following consists of inelastic dense irregular connective tissue? 5) this is used to reduce the friction between membranes of the heart. 6) this consists of mesothelium and connective tiessue. 7) which layer consists of cardiac muscle tissue? 8) this is used to increase the capacity of the atrium. 9) this marks the boundary between the ventricles. 10) these extend into the auricle 11) through which structure does blood pass from the right atrium to the right ventricle. 12) what types of tissue comprise the valves of the heart? 13) from the left ventricle, where does blood pass? 14) in a fetus, this structure temporarily shunts blood from the pulmonary trunk into the aorta. 15) as each ventricle contracts, where does blood move? 16) as each atrium contracts, where does blood move? 17) which of the below valves prevents blood from flowing back from the lungs? 18) in this disorder the aortic valve is narrowed. 19) this heart structure carries deoxygenated blood. 20) this vessel distributes oxygenated blood to the myocardium. 21) cardiac muscle fibers electrically connect to neighboring fibers by 22) which of the following contains the largest amount of mitochondria? 23) this is a network of specialized cardiac muscle fibers that provide a path for each cycle of cardiac excitation to progress through the heart. 24) this is the correct sequence of structures that allows the normal sequence of excitation to progress through the heart. 25) by comparison, cardiac muscle cells have contraction plateau time than skeletal muscle cells. 26) this is the volume of blood ejected from the left ventricle into the aorta each minute. 27) this term refers to the period of time during a cardiac cycle when contraction occurs and blood pressure rises. 28) which of theses periods represents greatest cardiac output? 29) the second heart sound represents which of the below events? 30) this part of the heart can initiate a contraction and can set a constant heart raet of about 100 beats per minute. 31) simulation of this nerve reduces heart rate. 32) which of the below reduces heart rate? 33) this part of the brain regulates heart rate. 34) this elctrical event represents repolarization of the ventricle.
