Your skeleton - it also functions as an endocrine organ.
Support: ex. pelvis supports internal organsProtection: Skull protects brain, vertebrae proctects spinal cordMovement: Skeletal Muscles pull against bonesMineral Storage: Calcium and PhosphateHematopoiesis: Blood formation
The six functions of the skeleton are support, movement, protection, production of blood cells, storage of minerals and endocrine regulation. Support for the body and internal functions. Movement in day to day activities. It protects internal organs etc.
the skin
the skelatal system protects them with the ribs
The external structures of animals protect the animal from harm to internal organs. An example of an external structure is the skin and fur on a bear. The skin protects the internal organs, and the fur protects the skin.
The skeleton supports the body/gives it structure and protects internal organs.
A membrane/sac that that protects the body's major internal organs and allows them freedom of movement (for example, lung contractions).
The integumentary system protects and covers internal structures.
skeletal system
It is actually only three common structures since not all mollusks have shells. Here it is: Head- structure that contains the mouth, brain and sensory organs Foot- muscular structure that extends from the body and is used for movement Mantle- fleshy tissue that covers and protects the internal organs. It also secretes the shell for most mollusks :) B) =3 -_-

There are two system that do this. Your skeleton (bones) and your skin (integument).
