Question

if the respiratory system fails, which other body systems will eventually fail?
○ circulatory and digestive
○ circulatory, nervous and digestive
○ all body systems
○ genitourinary, nervous and musculoskeletal

Explanation:

The respiratory system is responsible for gas exchange (taking in oxygen and releasing carbon dioxide). All body systems require oxygen to function (for cellular respiration to produce energy, ATP). If the respiratory system fails, cells across all systems won't get enough oxygen, leading to their failure. For example, the circulatory system needs oxygen to pump blood, the nervous system needs it for neural activity, the digestive system for digestion, etc. So all body systems will eventually fail.

Answer:

C. All body systems
