A. The cardiovascular system
B. The digestive system
C. The nervous system
D. The endocrine system
12. What is the main function of neurons in the nervous system as related to CPR?
A. Neurons transmit electrical signals to release carbon dioxide.
B. Neurons relay messages to regulate heart functions during CPR.
C. Neurons synthesize enzymes for oxygen exchange.
D. Neurons control muscular contractions of the bronchioles.
13. In the context of CPR, why is the respiratory system crucial for sustaining life?
A. It regulates the movement of oxygen from the alveoli to the bloodstream.
B. It filters oxygen through the liver before entering the body.
C. It controls the contraction of cardiac muscles to maintain circulation.
D. It processes sensory information related to blood oxygen levels.

A. Right atrium and left ventricle
B. Right ventricle and left atrium
C. Left atrium and left ventricle
D. Right atrium and right ventricle
15. How do the nervous and cardiovascular systems collaborate during the administration of CPR?

B. The cardiovascular system releases hormones to adjust oxygen levels.
C. The nervous system coordinates heart rate to ensure effective blood circulation.
D. The cardiovascular system communicates with the nervous system to regulate muscle contractions.
16. What is the primary indication for administering CPR?
A. Chronic heart disease
B. Sudden cardiac arrest

19. How do external chest compressions support the cardiovascular system during CPR?
A. By maintaining the heart's natural beat
B. By creating a vacuum to draw blood into the heart
C. By providing artificial circulation to deliver oxygen
D. By heating the body to increase blood flow
20. What happens if CPR is not administered within 6 minutes after cardiac arrest?
A. Brain damage occurs due to lack of oxygen
B. The heart automatically restarts itself
C. The cardiovascular system self-corrects
D. Organ functionality improves spontaneously
