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?
What is homeostasis?
The process by which the body maintains a stable internal environment despite external changes.
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.
Describe a scenario where homeostasis would be disrupted.
Answers may vary. (ex. When a person gets too hot but doesn't sweat, their body temperature will rise)
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.
Provide an example of two body systems working together for an athlete.
The muscular system and circulatory system work together to provide the muscles with oxygen and nutrients during exercise.
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.
Explain how temperature regulation is an example of homeostasis.
When the body gets too hot, it sweats to cool down. When it is too cold, it shivers to generate heat. This keeps internal temperature stable.
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.
How does the endocrine system work with the nervous system?
The nervous system sends signals that trigger the release of hormones, which affect various body functions.
Explain the importance of homeostasis in overall health.
Maintaining homeostasis is crucial for the body to function properly and to prevent illness or dysfunction.
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.
