What is chemical organisation?
The building blocks of the body
What is cellular organisation?
The basic structural and functional units of the body
What is tissue organisation?
Tissues are groups of cells that work together to perform a particular function
What are the four classes of tissue?

What is organismal organisation?
When all the parts of the body function together to constitute a living organism.
What is an example of chemical organisation?
Atoms and these joint to form molecules
What is an example of cellular organisation?

What is an example of tissue organisation?
Cardiac muscle
What is an example of organ organisation?
Heart
What is an example of system organisation?
Cardiovascular
What is an example of organismal organisation?
The individual
What does integumentary system do?
Skin
What are the three layers the integumentary system?
Epidermis (upper layer), dermis (middle layer), and hypodermis (bottom layer)
What does the dermis do?
Feeds the epidermis, lubricates hair shafts and controls sensation
What does hypodermis do?
Attaches skin to deeper layers
What does the muscular system do?
Provide skeletal movements, provide heat, protect skeleton and protect soft tissue
What do axial muscles do?
Provide support and positioning of the axial skeleton
What do appendicular muscles do?
Support and move brace limbs
What do tendons and aponeuroses do?
Translate contractile forces into motion
What is a tendon
Rope like connection between muscle and bone
What is an aponeuroses?
A sheet like connection most often muscle to muscle
What does the skeletal system compose of?
Bones, cartilage and joints
What does the axial skeleton do?
Protects brain and spinal chord, sense organs, and soft tissues. It also supports body weight over lower limbs
