4.5 Explain how the muscular/skeletal system (skeletal, smooth and cardiac muscles, bones, cartilage, ligaments, tendons) works with other systems to support the body and allow for movement. Recognize that bones produce blood cells.
MCAS Vocabulary
Cartilage - strong connective tissue at the ends of bone and in other areas
Ligament - connect bone to bone
Tendon - connect muscle to bone
Skeletal muscle - common skeletal muscle for movement of bones
Smooth muscle - muscles of the digestive tract
Cardiac muscle - heart muscle
