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 human body has more than 650 muscles, which make up half of a person's body weight. They are connected to bones by tough, cord-like tissues called tendons, which allow the muscles to pull on bones. If you wiggle your fingers, you can see the tendons on the back of your hand move as they do their work.
