The cholera bacterium produces toxins that cause chloride ions to be secreted into the small
intestine.
How does this affect the water potential of blood in the intestinal capillaries and the intestinal
contents?

apparently, the marking scheme said that the water potential would increase in the blood, and lowered in the intestine. I got the same answer as you but the marking scheme is so confusing.
