Breathing involves two primary processes: inhalation and exhalation. During inhalation, the diaphragm contracts and moves downward, while the intercostal muscles expand the rib cage, creating negative pressure that draws air into the lungs. Exhalation occurs when the diaphragm relaxes and the rib cage returns to its original position, forcing air out of the lungs. This cycle facilitates gas exchange, allowing oxygen to enter the bloodstream and carbon dioxide to be expelled.

What are two examples of events which may cause the arrests of breathing movements in humans?
Two examples of events that may cause the arrest of breathing movements in humans include sleep apnea, where breathing repeatedly stops and starts during sleep due to airway obstruction or central nervous system issues, and drowning, which can lead to a cessation of breathing due to water entering the lungs. Both situations can result in significant health risks, including hypoxia and potential loss of consciousness.
How does the breathing change when you exercise and then rest?
You body requires more oxygen when you work out. Your breathing rate changes according to your bodies need. Breathing rate is also both a voluntary and involuntary muscle contraction. Meaning you can control it (to some extent...i.e. Temporarily holding your breath) but during events such as sleep or if you were quadriplegic, your brain is able to maintain breathing subconsciously.
