The bones in the pelvis, legs and feet support the weight of the
upper body. Without a skeleton we would be a wobbly, floppy
mass of cells and tissue, unable to stand.
A - Attachment
Muscles attach to the bones of the skeleton and pull them into different positions.
This allows many types of movement at joints
D - Development of blood cells
1. Source of blood cells - many bones are hollow
and consist of spongy bone tissue which is filled
with red marrow
2. The facial bones have air sacs (sinuses) which are lined with epithelial
tissue which produces mucus to keep bacteria at bay
P - Protection
The various parts of the skeleton protect the underlying structures
A - Allows moment
Through a series of muscles pulling on the bones and joints for movement
M - Mineral stores
Calcium makes bone hard and is used maintain the compact tissue of bones.
