Which of the following is not a function of the mammalian skeleton? A. Protection B. respiration C. Transportation D. Support Detailed SolutionThe major functions of the skeletal system are body support, facilitation of movement, protection of internal organs, storage of minerals and fatWith the help of the lymphatic and circulatory systems, the skeletal system works with the respiratory system by creating red blood cells in the bones that aid in respiration facilitated by the lungs. |
