facilitates gas exchange between cells and the environment
Breaks down food into usable nutrients
Responsible for transport through the body
Extracts and excretes dissolved waste product from the blood
secretes chemical signals that allow body systems to respond to environmental changes and to one another
allows us to perceive and respond to the world around us
gives the body structure
largest organ of the body that forms a physical barrier between the external environment and the internal environment that it serves to protect and maintain.
responsible for absorbing fat from the digestive system, maintaining fluid balance, and supporting the cells of the immune system
facilitates the production of offspring
Allows the body to move

Body systems and their functions
Integumentary system - The largest organ of the body that forms a physical barrier between the external environment and the internal environment that it serves to protect and maintain.
Muscular system - Allows the body to move
Reproductive system - facilitates the production of offspring
Endocrine system - secretes chemical signals that allow body systems to respond to environmental changes and to one another
Urinary system - Extracts and excretes dissolved waste product from the blood
Digestive system - Breaks down food into usable nutrients
Lymphatic system - responsible for absorbing fat from the digestive system, maintaining fluid balance, and supporting the cells of the immune system
Respiratory system - facilitates gas exchange between cells and the environment
Nervous system - allows us to perceive and respond to the world around us
Skeletal system - gives the body structure
Circulatory system - Responsible for transport through the body

Cell characteristics of different organisms
Slide 23 - Slide
Biology has a hierarchical organisation which consists of multiple levels named:
1.
2.
3.
etc.
Cells from different organsims have different characteristics:
1. cell wall
2. chloroplast
3. nucleus
4. etc.
The level of organ systems is distinguishes 11 systems which form an organism
