, THE BODY IN MOTION - CORE 2
The Skeletal System
Functions of the Skeleton
● Support → supports organs and tissues in our body
● Protection → provides protection for internal organs
● Movement → bones provide a base of attachment for the muscles
● Mineral Storage → bones store minerals required for the body to function (e.g.
calcium)
● Blood Cell Production → red and white blood cells are produced in bone marrow
● Storage of Energy → parts of our body stores energy
Fibrous bands that connect bone to bone. Tough inelastic cords that attach muscles to
Ligaments maintain stability in the joint. bones. These further strengthen the joint
and allow the joint to move.

Respiratory System
Every cell in the body needs a continual supply of oxygen. The respiratory system is
responsible for the constant exchange of gases O2 and CO2.
1. Air containing O2 is
inhaled through the nose or
mouth where it is warmed,
moistened and filtered.
2. O2 goes through the
pharynx and the trachea.
3. O2 goes through the
bronchus (bronchi = both.
4. O2 reaches the
bronchioles where there are
alveoli. This is where the
exchange of gases (O2 and
CO2) or diffusion takes
place.
INSPIRATION EXPIRATION
Air goes in causing: Air goes out causing:
- Lungs expand - Lungs compress
- Diaphragm contracts - Diaphragm relaxes
- Ribs move up and out - Ribs move down and in
