Step-by-step explanation:
The functions of the muscular system are movement, posture, and generating heat. Muscles work together with bones and joints to enable movement and maintain posture. They also generate heat through muscle contractions, which helps to regulate body temperature.
While muscles do not directly create cell signals or blood cells, they are involved in processes that support these functions. For example, smooth muscles in blood vessels help to regulate blood flow and pressure, and skeletal muscles can aid in lymphatic circulation. However, the primary functions of the muscular system are related to movement and energy production.
Balance and sensing the environment are not typically considered primary functions of the muscular system, although some muscles, such as those in the eyes and ears, may contribute to sensory processing and balance.
