    Cardiovascular System
    Which statement regarding the regulation of blood pressure by the endocrine system is correct?

    One of the following is an example of osmosis. Which one?
    Osmosis refers to the movement of water through a membrane in the direction of its concentration gradient. A 0.8% solution is hypotonic to the contents of the RBC so water would enter the cell. In both choice A and C, the water is moving due to a hydrostatic pressure difference.
