Final answer:
The skeletal system is composed of bones, cartilage, and ligaments, which provide structure, protection, movement, and other vital functions to the body.
Step-by-step explanation:
The components that make up the skeletal system are bones, cartilage, and ligaments. The functions of the skeletal system include providing support to the body, shaping the body, protecting internal organs, aiding in movement, and producing blood cells. Additionally, the skeletal system plays a crucial role in maintaining homeostasis and producing endocrine hormones. Bones are living organs made of dense connective tissues, primarily collagen, and are hardened by minerals like calcium. Cartilage is a type of dense connective tissue that is strong, flexible, and smooth, covering the ends of bones at joints. Ligaments are bands of fibrous tissue that connect bones together and maintain the skeleton's structure.
