Understanding Body Systems

Which body system is responsible for transporting oxygen, nutrients, and waste throughout the body?

• Digestive System

• Circulatory System

• Respiratory System

• Nervous System

What is the primary function of the respiratory system?

• Breaking down food for energy

• Removing waste from the body

• Supplying oxygen and removing carbon dioxide

• Producing hormones for body regulation

Which system detects stimuli and sends signals to coordinate body responses?

• Circulatory System

• Nervous System

• Excretory System

• Integumentary System

The endocrine system helps regulate body functions by:

• Producing hormones

• Pumping blood

• Filtering waste

• Breaking down food

What is the primary function of the immune system?

• Breaking down food for nutrients

• Protecting the body from infections and diseases

• Transporting oxygen throughout the body

• Sending signals to process stimuli

Which system forms a protective barrier for the body and helps regulate temperature?

• Nervous System

• Circulatory System

• Digestive System

• Integumentary System

Which two systems work together to remove carbon dioxide from the body?

• Circulatory and Nervous

• Respiratory and Digestive

• Circulatory and Respiratory

• Nervous and Immune

What body system interacts with the nervous system when a person experiences itching from an irritant?

• Circulatory

• Integumentary

• Respiratory

• Digestive

Which response helps maintain homeostasis when carbon dioxide levels increase in the blood?

• Decreasing heart rate

• Increasing breathing rate

• Shivering to warm the body

• Slowing oxygen absorption

What is a feedback loop in the human body?

• A process where the body responds to a stimulus to maintain balance

• The breakdown of food for nutrients

• The transport of oxygen throughout the body

• A system that pumps blood through vessels
