Question

13 14 The source of blood carried to capillaries in the myocardium would be the 15 1 point The fact that the left ventricle of the heart is thicker than the right ventricle reveals that it 0000 Aorta Coronary veins Coronary arteries Pulmonary veins Pumps a greater volume of blood Sends blood through a smaller valve Expands the thoracic cage Pumps blood against a greater resistance 1 point If the length of time between action potentials in cardiac muscle cells was the same as it is for skeletal muscle cells Tetanic contractions might occur which would stop the heart s pumping action It would be much longer before cardiac cells could respond to a second stimulation Contractions would last as long as the refractory period Pacemaker cells would cease to spontaneously depolarize 1 point Compared to skeletal muscle cardiac muscle Lacks striations Cells are larger than skeletal muscle cells
