Moving Muscles and Bones: the Muscular System

The video explains the muscular system, highlighting its role in movement, breathing, digestion, and blood circulation. It describes three types of muscle tissue: skeletal, cardiac, and smooth. Skeletal muscles, attached to bones, enable movement. Cardiac muscle, found only in the heart, pumps blood throughout the body. Smooth muscle, located in organs, aids in digestion and other involuntary functions.
