c.Valves are located in veins to prevent blood from flowing backward because venous pressure is too low to keep the blood moving back toward the heart.
Why are valves located in veins but not in arteries? (Module 19.4A) a.Valves are located in veins because they have three wall layers instead of the two layers that arteries have. b.Valves are located in veins because the wall is thin enough to accommodate the valve. c.Valves are located in veins to prevent blood from flowing backward because venous pressure is too low to keep the blood moving back toward the heart. d.Valves are located in veins because veins are the only type of blood vessel where blood travels one-way instead of both ways in the vessel. e.Valves are located in veins because veins see the highest blood pressures so the valves protect the walls of the veins.

Why does a man have a deeper voice and a larger larynx than a woman? (Module 27.13B) Select one: a.Males are typically larger than females and their larynx is also larger causing a deeper voice. b.Males do not talk as much as females so their laryngeal musculature is not as well developed causing a larger larynx and a deeper voice. c.During fetal development, males lay down more laryngeal tissue than females causing a deeper voice. d.Males have proportionally larger necks than females so the development of the larynx has more room to expand and this causes a deeper voice. e.During puberty, testosterone causes greater laryngeal development than estrogen so a male will have a larger larynx and a deeper voice.
b.Tetany does not occur because cardiac muscle has a long refractory period that continues until relaxation is well under way so summation cannot occur, and thus tetany cannot occur.
Why does tetany not occur in cardiac muscle? (Module 18.11A) a.Tetany does not occur because the depolarizations in cardiac muscle are not sufficient to cause the formation of action potentials. b.Tetany does not occur because cardiac muscle has a long refractory period that continues until relaxation is well under way so summation cannot occur, and thus tetany cannot occur. c.Tetany does not occur because cardiac muscle cells are branched instead of lying in parallel fibers like skeletal muscle. d.Tetany does not occur because the sarcoplasmic reticulum in cardiac muscle does not hold as much calcium for maximum sustained contractions. e.Tetany does not occur because the gap junctions in cardiac muscle prevent the sustained contraction.

Why is the left ventricle more muscular than the right ventricle? (Module 18.6A) a.The left ventricle is supplied with more coronary vasculature so it hypertrophies over time, whereas the right ventricle receives less blood so it atrophies over time. b.The left ventricle must generate enough force to propel blood through the systemic circuit, whereas the right ventricle must generate only enough force to propel blood the short distance from the heart to the lungs in the pulmonary circuit. c.The left ventricle pumps a higher volume of blood to the systemic circuit than the volume of blood the right ventricle pumps to the pulmonary circuit. d.The left ventricle began forming earlier in development so it grew larger than the right ventricle. e.The left ventricle supplies blood to the brain and vital organs so it must be more reliable than the right ventricle which supplies blood to the limbs.
