AP PSYCHOLOGY

Detailed explanation-1: -Skeletal muscle and bone are no longer viewed from the simple mechanical perspective; i.e., bone provides an attachment site for skeletal muscles and skeletal muscles apply load to bone.

Detailed explanation-2: -Red blood cells are formed in the red bone marrow of bones. Stem cells in the red bone marrow are called hemocytoblasts. They give rise to all of the formed elements in blood. If a stem cell commits to becoming a cell called a proerythroblast, it will develop into a new red blood cell.

Detailed explanation-3: -The skeleton supports the body against the pull of gravity. The large bones of the lower limbs support the trunk when standing. The skeleton also protects the soft body parts. The fused bones of the cranium surround the brain to make it less vulnerable to injury.

Detailed explanation-4: -The skeletal system works as a support structure for your body. It gives the body its shape, allows movement, makes blood cells, provides protection for organs and stores minerals.
