Presumably you're asking about the compact osseous (bone) tissue.
Weight-bearing bones include the femur (thigh bone), tibia and fibula (lower leg bones), and the bones of the foot such as the talus, calcaneus, and metatarsals. These bones support the body's weight during activities like standing, walking, and running.
Long bones are thickest in the diaphysis, which is the shaft or long central part of the bone. This thickened area provides strength and support to withstand the stresses experienced during weight-bearing activities. The structure is reinforced by compact bone, which helps to resist bending and torsional forces. Additionally, the thickness decreases towards the ends of the bone, where the epiphyses are located.
Fibula
Yes, bones are classified as weight-bearing or protective based on their primary functions. Weight-bearing bones, like those in the legs, support the body's weight and provide structure for movement. Protective bones, such as those in the skull or ribcage, help shield vital organs from injury.
It makes the bones stronger.

Compact (dense) tissue is characterized by a tightly packed structure, providing strength and support to bones. It forms the outer layer of bones and is essential for weight-bearing and protection. Cancellous (spongy) tissue, on the other hand, has a porous, lattice-like structure that reduces bone weight while maintaining strength. It is typically found at the ends of long bones and within the interior of others, playing a key role in producing blood cells and storing marrow.
Bones are made through a process called ossification, where bone tissue is formed and developed. Osteoblasts are cells responsible for creating new bone tissue, which then mineralizes and hardens to form bones. A diet rich in calcium, phosphorus, and vitamin D, along with weight-bearing exercise, helps support healthy bone formation.
The diet will ensure the elements you need to make and repair bones are present in your body as needed. Weight bearing stresses on bones causes electricity in the bones to be generated these micro electric currents stimulate the bones to strengthen in response. Thus in space where there is no gravity to cause weight, the bones of astronauts weaken (despite a good diet) and they have to exercise against springs to cause stresses in their bones.
