Human Body Systems

How do the muscular and nervous systems work together?

• The muscular system sends signals to the nervous system to initiate movement.

• The nervous system sends signals to the muscular system to initiate movement.

• The muscular system and nervous system operate independently without interaction.

• The nervous system only regulates the heart and not the muscles.

What is the function of the nervous system?

• The nervous system controls and coordinates the body's responses to internal and external stimuli.

• The nervous system is responsible for the production of hormones in the body.

• The nervous system aids in the digestion of food and absorption of nutrients.

• The nervous system helps in the formation of blood cells in the bone marrow.

What is the main function of the heart?

• The heart pumps blood throughout the body.

• The heart regulates body temperature.

• The heart produces hormones for digestion.

• The heart filters toxins from the blood.

What is the role of the circulatory system?

• To transport blood, nutrients, and oxygen to cells and remove waste.

• To digest food and absorb nutrients.

• To provide structural support to the body.

• To regulate body temperature and maintain homeostasis.

What is the role of the lungs in the respiratory system?

• The lungs facilitate the exchange of oxygen and carbon dioxide.

• The lungs produce hormones that regulate blood pressure.

• The lungs filter toxins from the blood.

• The lungs store oxygen for later use.

What organ is part of the digestive system?

• The stomach

• The heart

• The lungs

• The brain

What is homeostasis?

• Homeostasis is the body's ability to maintain a stable internal environment.

• Homeostasis is the process of cell division in living organisms.

• Homeostasis refers to the body's response to external stimuli.

• Homeostasis is the mechanism of energy production in cells.

What is the function of the brain?

• The brain processes information and coordinates the body's activities.

• The brain regulates body temperature and hormone levels.

• The brain is responsible for digestion and metabolism.

• The brain controls the immune system and fights infections.

What is the primary function of the respiratory system?

• To circulate blood throughout the body.

• To take in oxygen and remove carbon dioxide from the body.

• To digest food and absorb nutrients.

• To regulate body temperature.

What is the function of the immune system?

• The immune system protects the body from infections and diseases.

• The immune system helps in digestion and nutrient absorption.

• The immune system regulates body temperature.

• The immune system is responsible for muscle movement.
