capillary and cardiac output questions need help??

1.) how could u force more fluid from the capillaries into the tissues(that increases the volume of intestitial fluid)?

2.)what would not result in the dialation of the arterioles in a continuous capillary bed??

3.)select the correct statement:
   
    a.) the more the heart muscle is streched, the lower the cardiac output
    b.) increased sympathetic stimulation will lead to higher cardiac output
    c.) decresed sympathetic stimulation will lead to higher cardiac output
    d.) increasing the afterload will increase cardiac output
    e.) increased Ca+ concentration via chemicals or drugs will cause more powerful contractions
