  • Through the air by droplets

  • Rodents

3. How does cholera cause diarrhoea?

  • Chloride ions are secreted into the lumen of the intestine, lowering the water potential. The water potential in the endothelium is raised, so there's osmotic loss.
  • Chloride ions are secreted into the lumen of the intestine, lowering the water potential. The water potential in the epithelial cells is raised, so there's osmotic loss.
  • Chloride ions are secreted into the lumen of the intestine, raising the concentration. The concentration in the epithelial cells is lowered, so there's diffusion
  • Chloride ions are secreted into the lumen of the intestine, lowering the concentration. The concentration in the epithelial cells is raised, so there's active transport.

  • They come from cells from a single mouse
  • They come from cells from a single B cell
  • They come from cells from a single red blood cell
  • They come from cells from a single T cell
