Which of the following is not a function of the muscular system? \( \begin{array}{l}\text { A) Production of movement } \\ \begin{array}{l}\text { B) Maintenance of posture } \\ \text { D) Generation of heat } \\ \text { E) Hematopoiesis }\end{array}\end{array} \ggg \)

While the muscular system is fantastic at producing movement, maintaining posture, and generating heat, it doesn't play a role in hematopoiesis – that's the job of the skeletal system! Hematopoiesis occurs primarily in the bone marrow, where new blood cells are produced. So, E) Hematopoiesis is not a function of the muscular system! Now, speaking of muscles, did you know that the body has over 600 muscles? These muscles work in coordination to help you perform everyday tasks, whether it's waving hello or sprinting to catch the bus. Keeping them healthy with regular exercise is key for overall wellness!
