well if you are talking about what I'm talking about it is the exoskeleton. and I just want to give a shout out to my idol Steven Tyler
that would be a exoskeleton. A exoskeleton is an external skeleton that supports and protects an animal's body
The skeleton supports the body/gives it structure and protects internal organs.
An exoskeleton is an external skeleton that supports and protects an animal's body, in contrast to the internal endoskeleton which humans and other mammals have
The nose and naval cavity from the main external opening for the respiratory system and its the first section of the body's airway's nose is a structure of the made of cartilage bone,muscle and skin that supports and protects the anterior portion of the nasal cavity.
The Skeletal System protects all your organs and supports the body.
The two phyla of animals that contain an exoskeleton are Arthropoda, which includes insects, spiders, and crustaceans, and Mollusca, which includes animals like snails and clams.
