Human Body Review

What is the main function 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 facilitate gas exchange in the lungs.

How do the skeletal and muscular systems work together?

• The skeletal system provides a framework for muscles to pull against, enabling movement.

• The muscular system protects the skeletal system from injury.

• The skeletal system generates heat for muscle contraction.

• The muscular system stores minerals for the skeletal system.

How does the nervous system interact with the muscular system?

• The nervous system sends signals to the muscles to cause movement.

• The muscular system generates signals to the brain for processing.

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

• The muscular system controls the heart rate and blood pressure.

What is the role of the spinal cord?

• To produce hormones for the body

• To transmit signals between the brain and the rest of the body

• To filter toxins from the blood

• To store memories and experiences

What are the main parts of the digestive system?

• Lungs, heart, and kidneys.

• Esophagus, stomach, and intestines.

• Brain, spinal cord, and nerves.

• Skin, hair, and nails.

What is the primary function of the digestive system?

• To break down food and absorb nutrients.

• To circulate blood throughout the body.

• To provide structural support to the body.

• To regulate body temperature.

What is the role of the lungs in the body?

• The lungs take in oxygen and expel carbon dioxide.

• The lungs filter toxins from the blood.

• The lungs produce hormones for digestion.

• The lungs store excess nutrients for energy.

Which system provides structure and support to the body?

• The muscular system.

• The circulatory system.

• The skeletal system.

• The respiratory system.

Which two body systems work together to enable movement?

• The circulatory and respiratory systems.

• The skeletal and muscular systems.

• The digestive and excretory systems.

• The nervous and endocrine systems.

What is homeostasis?

• Homeostasis is the process by which the body maintains a stable internal environment.

• Homeostasis is the body's ability to adapt to external changes.

• Homeostasis refers to the body's response to infections.

• Homeostasis is the mechanism of muscle contraction.
