Movement into and out of cells — practice question

If children have too little protein in their diet, this may cause a disease in which excess tissue fluid collects in the abdomen. What accounts for the build-up of excess tissue fluid in this disease?

  • AA shortage of plasma proteins decreases blood water potential; less tissue fluid returns to the blood.
  • BA shortage of plasma proteins increases blood water potential; less tissue fluid returns to the blood.
  • CA shortage of protein in the diet causes weak cardiac muscle, reducing hydrostatic pressure.
  • DA shortage of protein in the tissue fluid decreases its water potential; more water leaves the blood.
