Skeletal, Smooth and Cardiac muscles.
The muscular system is responsible for the movement of the human body. Attached to the bones of the skeletal system are about 700 named muscles that make up roughly half of a person’s body weight. Each of these muscles is a discrete organ constructed of skeletal muscle tissue, blood vessels, tendons, and nerves. Muscle tissue is also found inside of the heart, digestive organs, and blood vessels. In these organs, muscles serve to move substances throughout the body.... The main function of the muscular system is movement. Muscles are the only tissue in the body that has the ability to contract and therefore move the other parts of the body. Related to the function of movement is the muscular system’s second function: the maintenance of posture and body position. Muscular System. The muscular system is made up of tissues that work with the skeletal system to control movement of the body. Some muscles—like the ones in your arms and legs—are voluntary, meaning that you decide when to move them. Other muscles, like the ones in your stomach, heart, intestines and other organs, are involuntary.  There are just the three different types of tissues that make up different organs. The heart is made up of many tissues but one of the main tissues is the cardiac tissue which is a muscular tissue and then there is the skeletal tissue and smooth tissue. The skeletal tissue is connected to the bone.  The major organs of the Muscular System are the muscles. The 3 types of muscles are the smooth, cardiac, and skeletal muscles. The functions of the muscular system are locomotion or mobility,  strength, heat production, shock absorption, shaping the body,  maintaining posture, and respiration. In ad … dition it plays a role  in the digestive process by peristalsis to move the food through The muscles of the body enable individuals to stand upright, walk and pick up heavy objects. Those very same muscles enable the heart to beat, the lungs to breathe and internal organs to function. A variety of organs as well as muscle tissues are included in the body's muscular system, each with a specific job to do. Muscular tissues are found throughout the body and include more than those bulging biceps or six-pack abs. The heart is made up exclusively of cardiac tissues and is one of the most muscular organs in the body, beating at an average of 72 times per minute (or approximately 3.5 billion times during a lifetime), states the Texas Heart Institute. The muscular system is an organ system consisting of skeletal, smooth and cardiac muscles. The muscular system in vertebrates is controlled through the nervous system, although some muscles (such as the cardiac muscle) can be completely autonomous. Three types of muscles. The muscular system can be broken down into three types of muscles: skeletal, smooth and cardiac, according to the NIH. Skeletal muscles are the only voluntary muscle tissue in the human body and control every action that a person consciously performs.  The muscular system parts refer to the types, locations and the number of muscular organs in the human body, as you can see in the muscular system diagram. According to the most recent research findings related to the human anatomy, there are more than 700 types...  The Human Body: Muscular system. The muscular system is the largest system in the body. Muscles are located in practically every region of the human body. The muscular system is made up of tissues that work with the skeletal system to control movement of the human body. Muscles function is to produce force and cause motion.
