how many words is this What are muscles? Muscles are soft tissue that control all movement in the body. Muscles work together with our bones in order to help us move. They also help us see, hear, breath, digest food and pump blood through our hearts and blood vessels. Muscles are used for day to day actions and play a role in just about everything we do. The human body has more than 600 muscles working together in our body to help us move or to just keep us alive. There are three types of muscle tissue in our bodies, these include: Skeletal, Cardiac and Smooth muscles. The Skeletal muscles are part of your musculoskeletal system. They work with our bones, tendons and ligaments to support your weight and move you. Cardiac muscles make up the middle layers of our heart. Cardiac muscles pump blood through your cardiovascular system. Our heart is an involuntary muscle, it can do what it needs to do without needing an input. Lastly, Smooth muscles. These muscles are involuntary that line the inside of our organs, they do stuff like moving waste through our intestines and helping our lungs expand when you breathe. They also play an important role in female and male reproductive systems, urinary system, digestive system and the digestive system. The two basic types of muscle fibers are Type I (slow-twitch) fibers, which are endurance-oriented and resistant to fatigue, and Type II (fast-twitch) fibers, which are designed for explosive power and speed but fatigue more quickly. Muscle function is an important topic in biology, and it can be understood by looking at three main types of muscle contractions: isotonic, isometric, and eccentric contractions. Isotonic contractions occur when muscles shorten or lengthen while producing force, isometric contractions happen when muscles generate force without changing their length, and eccentric contractions involve muscles lengthening while still under tension. In conclusion, muscles play an important role in our day to day lives.
