Water is transported through the plant in Xylem vessels, these begin in the roots and end in the leaves of the plant, water is translocated through a combination of “Transpirational pull” and capillary action. Xylem is one of two “conductive” tissues responsible for moving water and the products of photosynthesis (glucose) through the plant, the tissue responsible for moving the “food” around is Phloem.

Kidneys are essential in the urinary system and also serve homeostatic functions such as the regulation of electrolytes, maintenance of acid–base balance, and regulation of blood pressure (via maintaining salt and water balance). They serve the body as a natural filter of the blood, and remove wastes which are diverted to the urinary bladder whereas the antibodies are produced by antigens in the cell.
