LEVELS OF ORGANIZATION
This is the smallest living unit that carries out life processes.
What is a cell?
This system moves oxygen, nutrients, and wastes throughout the body.
What is the circulatory system?
These two systems work together to move oxygen from air to body cells.
What are the respiratory and circulatory systems?
The brain and spinal cord together make up this part of the nervous system.
What is the central nervous system?
This type of digestion involves chewing and stomach movement.
What is mechanical digestion?
This level forms when similar cells work together to do the same job.
DOUBLE JEOPARDY
What is a tissue?
This system breaks food down so the body can use it for energy.
What is the digestive system?
These two systems allow your arm to bend when you lift a backpack.
What are the muscular and skeletal systems?
This part of the nervous system carries messages throughout the body.
What is the peripheral nervous system?
This process uses enzymes to break food into usable parts.
DOUBLE JEOPARDY
What is chemical digestion?
This structure contains more than one tissue type working together.
What is an organ?
This system sends fast signals that control movement and reactions.
What is the nervous system?
This system tells the heart to beat faster during exercise.
What is the nervous system?
This response prepares your body to react quickly during stress.
What is fight or flight?
Most nutrients enter the bloodstream in this organ.
What is the small intestine?
This level allows the body to carry out major functions like breathing or digestion.
What is an organ system?
This system provides structure and protects organs like the brain and heart.
What is the skeletal system?
Why is digestion not helpful without another system involved?
Because nutrients must be transported by the circulatory system.
This response helps your body relax and digest food.
What is rest and digest?
Why doesn’t digestion alone give cells energy?
Because nutrients must be transported by the circulatory system.
Why would the body fail if it skipped one level and went straight from cells to systems?
Because each level depends on the one before it to perform more complex jobs.
Which system would still fail without help from others—even if it was working perfectly?
All body systems (none work alone).
Explain one cause-and-effect relationship between two body systems.
Example: Faster breathing increases oxygen, which the circulatory system delivers to cells.
Why is it helpful that your body can switch between the sympathetic and parasympathetic systems?
It allows the body to respond to danger and also recover afterward.
Trace the path of nutrients from food to muscle cells.
Food → digestion → absorption → blood → cells.
