What is the primary function of the skeletal system?
The primary function of the skeletal system is to provide support, protect internal organs, and enable movement, as well as produce blood cells and store minerals.
What type of muscle is responsible for voluntary movements?
Skeletal muscle.
What is the main function of the heart in the circulatory system?
he heart pumps blood throughout the body, delivering oxygen and nutrients to tissues and removing waste products.
What is the primary function of the lungs in the respiratory system?
The lungs facilitate the exchange of oxygen and carbon dioxide between the blood and the atmosphere.
What is the main role of the lymphatic system?
The lymphatic system helps to defend against infections, remove waste, and maintain fluid balance.
What is the name of the flap that prevents food from entering the windpipe?
The epiglottis.
What is the primary function of the small intestine?
The small intestine is responsible for nutrient absorption from digested food.
What part of the brain is responsible for controlling balance and coordination?
The cerebellum.
What is the difference between the sympathetic and parasympathetic nervous systems?
The sympathetic nervous system prepares the body for "fight or flight" (stress response), while the parasympathetic nervous system controls "rest and digest" functions (calming the body).
What hormone does the pancreas secrete to regulate blood sugar levels?

What is the difference between active and passive immunity?
Active immunity occurs when the body produces its own antibodies (e.g., through infection or vaccination), while passive immunity is acquired from another source, such as breast milk or antibodies from another person.
How do the circulatory and respiratory systems work together to maintain homeostasis?
The circulatory system transports oxygen from the lungs to tissues and carries carbon dioxide from tissues to the lungs for exhalation, supporting cellular respiration and homeostasis.
What is the primary role of the nephrons in the kidneys?
Nephrons filter blood to remove waste products, excess substances, and produce urine.
What are some common sensory sensitivities that individuals with autism may experience?
Individuals with autism may experience heightened or reduced sensitivity to sensory stimuli, such as lights, sounds, textures, or smells, which can lead to sensory overload or discomfort.
How can early intervention help children with autism spectrum disorder (ASD)?
