Answer 1

The muscular system is primarily composed of muscles and tendons. It includes skeletal, cardiac, and smooth muscles.

Step-by-step explanation:

The muscular system is primarily composed of muscles and tendons. There are three types of muscle: skeletal muscle (which is attached to bones by tendons and enables voluntary body movements), cardiac muscle (which makes up the walls of the heart and makes it beat), and smooth muscle (which is found in the walls of internal organs and other internal structures and controls their movements).
