Which system controls body activities by sending signals throughout your body?

• Excretory system

• Nervous system

• Respiratory system

• Circulatory system

Answer explanation

The nervous system controls body activities by transmitting signals through neurons, allowing for rapid communication between different parts of the body. It is essential for coordinating responses and maintaining homeostasis.

What system is responsible for filtering blood and removing waste from your body?

• Circulatory system

• Respiratory system

• Excretory system

• Nervous system

Answer explanation

The excretory system is responsible for filtering blood and removing waste from the body, primarily through the kidneys, which produce urine to eliminate toxins and excess substances.

Which term describes the organs that carry blood throughout your body?

• Blood vessels

• Nerve cells

• Air sacs

• Muscle tissue

Answer explanation

The term 'blood vessels' refers to the network of tubes, including arteries and veins, that transport blood throughout the body. Other options like nerve cells and muscle tissue do not serve this function.

What structures in the lungs are responsible for gas exchange?

• Blood vessels

• Nerve endings

• Alveoli/Air sacs

• Muscle fibers

Answer explanation

The alveoli, or air sacs, are the tiny structures in the lungs where gas exchange occurs. They allow oxygen to enter the blood and carbon dioxide to be expelled, making them essential for respiration.
