What is Muscular System?
The muscular system is an important part of the human body, allowing us to move and perform essential bodily functions. It is composed of more than 600 muscles and their associated tendons, which are responsible for providing movement, stability, and postural support. Muscles are also used to generate heat in response to cold temperatures or during exercise.The three types of muscle tissue found in the human body are skeletal muscle, cardiac muscle, and smooth muscle. Skeletal muscles attach to bones and create movement when they contract; they account for 40-50% of a person’s body weight. Cardiac muscles are located only in the heart and aid in pumping blood throughout the body while smooth muscles line organs such as intestines or stomachs to help push food through them. Each type of muscle plays an important role in keeping our bodies functioning properly; however some types can be overworked or injured from strain or repetitive motions like typing at a computer all day long. To promote healthy muscles it is important for individuals to engage in regular physical activity that includes both cardio exercises like running or swimming as well as strength training exercises such as lifting weights. Additionally getting enough rest (7-8 hours per night) helps ensure that our bodies have enough time to recover from intense workouts or daily activities so that our muscles can stay strong and healthy over time. Overall the muscular system is vital for our everyday lives; it allows us to move around freely while providing support for our posture, balance and stability among other things.
