Levels of Organization
The smallest level of organization
What is cells?
What is the main function of the muscular system?
What is movement
Which two systems work together to promote movement?
What is muscular and skeletal?
These are part of the circulatory system and carry the oxygen to other parts of the body.
What do the blood vessels do in the body?
What is the main function of the nervous system?
To receive stimuli, process information, and send signals to direct responses.
What is cells, tissues, organ, organ systems, and organism.
Provide an example of an organ.
Answers will vary (heart, lungs, skin, liver, kidney)
Describe the relationship between the nervous system and the muscular system.
The nervous system sends signals to the muscular system to move the body.
Humans have many cells that have their own functions in the body.
What is a multicellular organism?
How do the brain and nerves work together?
The brain interprets the signals received from the nerves, then sends back instructions for how to respond.
Define "Cell"
What is the smallest unit of life, makes up all living things
Provide an example of an organ system.
Answers will vary (circulatory, respiratory, muscular, skeletal, nervous)
They communicate and adjust their functions to keep the body stable, such as regulating temperature or blood pressure.
Green organelles in a plant cell that helps a plant produce its own food through photosynthesis.
What is a chloroplast?
What role does the brain play in interpreting stimuli?
The brain analyzes information and makes decisions on how to respond.
Define "Tissue"
What is a group of similar cells working together to perform a specific function?
Describe the function of the respiratory system.
What is brings oxygen into the body and removes carbon dioxide?
How does the circulatory system interact with other body systems?
What is works with respiratory system to get oxygen from lungs, works with digestive system to get nutrients from food. Together, they maintain homeostasis.
Sensory receptor -> Sensory neuron -> Brain/spinal cord -> Motor neuron -> Response
What is the correct general path a signal takes when you react to something in your environment?
What is the pathway for processing in the nervous system?
Stimulus ---> Sensory Receptors ---> Nerves ---> Brain ---> Nerves --->Muscle or Glands
Define "Organ"
What is a structure made up of different tissues working together to carry out a job.
Describe the function of the digestive system.
What is break down food into nutrients the body can use for energy.
Our nervous system can be affected by this injury by causing blurred vision as the brain doesn't process signals correctly when injured. Also the muscular system may be affected by making some body parts like our legs unable to move.
What body systems are affected from a concussion?
Provides structure and support to plant cells but is not in animal cells
What is the cell wall?
Describe how the nervous system responds when a soccer player kicks the ball.
The brain processes the visual information (where the ball is), sends signals for the leg muscles to contract, and directs the movement to kick the ball.
