Because they have evolved (or were designed, whichever you choose to believe) as to be the primary weight bearing limbs, so they have to be more sturdy to do that job than the upper limbs.
your arms are the upper limbs and your legs are the lower limbs :)
The bones of the lower limb from superior to inferior are the femur (thigh bone), patella (kneecap), tibia and fibula (lower leg bones), tarsal bones (ankle bones), metatarsal bones (foot bones), and phalanges (toe bones).
No, the axial skeleton consists of bones along the central axis of the body, including the skull, vertebrae, and ribcage. The appendicular skeleton consists of bones of the upper and lower limbs, as well as the shoulder and pelvic girdles.
Axial bones are those that are found within your head, vertebral (spinal) column, and ribcage. Any other bone is considered part of the appendicular skeleton; these include all bones related to the upper and lower limbs. This includes your clavicle (collarbone), scapula (shoulder blade), and pelvic bones, even though they are part of your torso (and obviously all bones that are further down in the limbs).
Wheelchair-bound individuals with paralyzed lower limbs develop thin and weak leg and thigh bones due to lack of weight-bearing physical activity that is needed to stimulate bone growth and strength. Weight-bearing activities help bones absorb calcium and other minerals, leading to stronger bone density. Without this stimulation, bones can become thin and weak over time.
The appendicular divison (126 bones) consist of the pectoral girdle, upper limbs, pelvic girdle, and lower limbs.

The sets of bones that support the limbs of vertebrates are called appendicular skeleton. It includes the bones of the upper and lower limbs, as well as their associated girdles (shoulder and hip). These bones provide the framework for movement and support in vertebrate animals.
Upper limbs= Scapula, clavical, humerus, radius, ulnar, 8 carpals, 5 metacarpals and 14 phalanges Xs 2= 64. Lower limbs= Coxal, femur, patella, tibia, fibula, 7 tarsals, 5 metatarsals and 14 phalanges Xs 2= 62.
The bones of the lower limb from superior to inferior are the femur (thigh bone), patella (kneecap), tibia and fibula (lower leg bones), tarsal bones (ankle bones), metatarsal bones (foot bones), and phalanges (toe bones).
The lower portion of the trunk of the body is called the pelvis. It consists of the hip bones, sacrum, and coccyx, and acts as a support structure for the spine and a connection point for the lower limbs.
The bones that form the longitudinal axis of the body, called axial skeleton. it has 3 main parts , skull, vertebral column and the bony thorax. Appendicular skeleton consists with bones of the limbs and girdles. ( upper limbs, lower limbs, pelvic girdle and shoulder girdles)

The adult human body has 206 bones. The Axial skeleton, which consists of all the bones in the head, the rib cage, the hyoid bone, the sternum, and vertebral column, has 80 bones. The Appendicular skeleton, which consists of the upper and lower limbs, has 126 bones.
The long bones are the femur (thigh bone), the tibia, fibula (2 leg bones)
The function of many bones is to move things especailly in the limbs wiith the help of muscles.
