Explain two key concepts of the sarcomere length-tension relationship
A) (1 ) The greater the zone of overlap, the greater the tension the muscle can develop; and (2 ) there is an optimum range of actin and myosin overlap that will produce the greatest amount of tension.
B) (1 ) The smaller the zone of overlap, the greater the tension the muscle can develop; and (2 ) there is an optimum range of actin and myosin overlap that will produce the greatest amount of tension.
C) (1 ) The greater the zone of overlap, the less tension the muscle can develop; and (2 ) there is an optimum range of actin and myosin overlap that will produce the greatest amount of tension.
D) (1 ) The greater the zone of overlap, the greater the tension the muscle can develop; and (2 ) there is an optimum calcium concentration that will produce the greatest amount of tension.
E) (1 ) The smaller the zone of overlap, the greater the tension the muscle can develop; and (2 ) there is an optimum calcium concentration that will produce the greatest amount of tension.

Why do veins have relatively thin walls?
A) It allows a typical vein to change the diameter of its lumen. B) It allows a typical vein to be stretched as its diameter increases during ventricular systole. C) A typical vein's wall allows exchange to occur quickly by diffusion across endothelial cells or through gaps between adjacent endothelial cells. D) A typical vein does not need to withstand much pressure. E) There are sphincters associated with the walls of veins, which allow vasomotion to occur.
