Based on the graph, which of the following is a function of the respiratory system?
A.
to deliver oxygen to cells for cellular respiration at different rates so that different amounts of energy can be made when needed
B.
to detect changes in the outside world through nerve impulses and send these impulses throughout the body
C.
to increase the breathing rate during heavy activity so that more carbon dioxide can be absorbed by respiratory cells
D.
to decrease a person's heartbeat during heavy activity and decrease the flow of blood to areas that will pool with blood
The correct answer is C. to increase the breathing rate during heavy activity so that more carbon dioxide can be absorbed by respiratory cells.
Based on the information provided, option A is a function of the respiratory system. The respiratory system is responsible for delivering oxygen to cells for cellular respiration. Different rates of oxygen delivery allow for different amounts of energy production based on the body's needs.
To determine which of the given options is a function of the respiratory system based on the graph, we need to analyze the information provided and consider the role of the respiratory system.
The respiratory system is responsible for the exchange of gases, specifically oxygen and carbon dioxide, between the body and the external environment. It plays a vital role in the process of respiration, which involves the inhalation of oxygen and the exhalation of carbon dioxide.
Let's examine each option:
A. To deliver oxygen to cells for cellular respiration at different rates so that different amounts of energy can be made when needed.
This option aligns with the primary function of the respiratory system. It accurately describes how the system delivers oxygen to cells based on their varying energy demands.
B. To detect changes in the outside world through nerve impulses and send these impulses throughout the body.
Detecting changes in the outside world and sending nerve impulses throughout the body is the function of the nervous system, not the respiratory system. Therefore, option B is incorrect.
C. To increase the breathing rate during heavy activity so that more carbon dioxide can be absorbed by respiratory cells.
Increasing the breathing rate during heavy activity is a function of the respiratory system. It allows for more efficient exchange of oxygen and carbon dioxide, ensuring an adequate supply of fresh oxygen to the cells and removal of waste carbon dioxide.
D. To decrease a person's heartbeat during heavy activity and decrease the flow of blood to areas that will pool with blood.
Regulating the heartbeat and blood flow is primarily the function of the circulatory system, not the respiratory system. Therefore, option D is incorrect.
Based on the analysis above, the correct answer is option A.
