Human skeleton explained to kids

The human skeleton is the internal framework of the human body. It is composed of around 206 bones, which form a network of stiff tissues that work together to support the body and enable us to move. The bones of the skeleton provide strength and support for the body, protect vital organs, and allow us to move. They also store minerals and produce blood cells. The skeleton is made up of two main types of bone: • Compact (dense) bone: This type of bone is strong and heavy. It makes up the outer layer of bone and is found in the arms, legs, and ribs. • Cancellous (spongy) bone: This type of bone is lighter and less strong than compact bone. It is found in the center of long bones, such as the femur (thigh bone), and in the vertebrae (bones of the spine). The human skeleton grows and changes throughout our lives. It starts to form during the early stages of development in the womb and continues to grow until we reach adulthood. During childhood and adolescence, our bones grow in length and size. This process is called ossification. As we get older, our bones may become thinner and weaker. This is due to a loss of bone density, which is a normal part of the aging process. This can make us more susceptible to fractures (breaks in the bone). There are many different diseases and conditions that can affect the skeleton. These include osteoporosis, arthritis, and bone cancer.
