It covers the internal and external surfaces of the body. In other words, it is the body's protective barrier. Its main function is to protect the organs, absorb nutrients, release substances such as enzymes and hormones, and allow exchange between the inside of the body and the external environment.

It provides structural support to the body, connects organs and tissues, and protects internal structures. It includes components such as bones, cartilage, blood, and fat, which play key roles in the stability and functioning of the body.

It is the engine of the body. It makes movement possible, from the heartbeat to the most subtle gestures, thanks to the contraction of its fibers.

It is the body's communication network. It transmits electrical impulses between the brain, spinal cord and organs, allowing you to perceive, think and react accurately.
