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.
All movement in the body is controlled by muscles. Some muscles work without us thinking, like our heart beating, while other muscles are controlled by our thoughts and allow us to do stuff and move around. There are over 650 muscles in the human body.
