Muscular system

Explanation:

The muscular system is made of three types of muscles namely, smooth muscles, cardiac muscle, and skeletal muscles. Muscles are also attached to bones. Contraction of muscles leads to movement of the body. The main function of the integumentary system is to cover and protect the body. The digestive system is involved in ingestion of food, its breakdown into simpler elements and their absorption. The endocrine system maintains homeostasis by secretion of hormones.
