In biology class one day, Mrs. Chabon wrote six physiological functions on the board. Then, she asked groups of students to each
choose the three functions that are purposes of the excretory system. These are the lists they made. Group 1: maintaining pH level of blood; transporting hormones throughout the body; regulating growth Group 2: removing wastes from the body; digesting solid foods; maintaining salt and water balance Group 3: maintaining salt and water balance; maintaining pH level of blood; regulating growth Group 4: removing wastes from the body; maintaining pH level of blood; maintaining salt and water balance Which group correctly listed the functions of the excretory system? group 1 group 2 group 3 group 4
I believe the answer is group 4 Excretory system removes all the wastes from the body through the creation of feces and Urine, maintains the PH level trough the regulation of H+ from the kidneys, and maintaining water balance by controlling the water concentration within the blood plasma during the excretion process of Urea.
