Vitamin B12 is one of the most common topics I get asked about for those interested in a plant-based diet. I think we have a natural tendency to make sure we are getting enough of everything, and vitamin B12 is a legitimate concern for exclusively plant-based eaters, so it causes a fair amount of anxiety.
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 personâs body weight. Each of these muscles is a discrete organ constructed of skeletal muscle tissue, blood vessels, tendons, and nerves.uscles 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 systemâs second function: the maintenance of posture and body position.
The muscular system is made up of tissues that work with the skeletal system to control movement of the body. Some musclesâlike the ones in your arms and legsâare voluntary, meaning that you decide when to move them. Other muscles, like the ones in your stomach, heart, intestines and other organs, are involuntary. This means that they are controlled automatically by the nervous system and hormonesâyou often don't even realize they're at work. The body is made up of three types of muscle tissue: skeletal, smooth and cardiac. Each of these has the ability to contract and expand, which allows the body to move and function. . 1  Skeletal muscles help the body move.
