Lungs expel waste from the body in the form of (1 point)
A. Carbon Dioxide
B. Blood Cells
C. Water
D. Oxygen
A. Carbon Dioxide
A. Carbon Dioxide
The correct answer is A. Carbon Dioxide.
To find the answer, we can start by considering the function of the lungs. Lungs are responsible for the exchange of gases in the body, primarily oxygen and carbon dioxide. When we breathe in, oxygen is taken into the lungs and then transported to the bloodstream to be delivered to the cells of the body. On the other hand, carbon dioxide, which is a waste product produced by the cells during cellular respiration, is transported by the bloodstream to the lungs. From there, it is exhaled out of the body when we breathe out.
So, by analyzing the purpose of the lungs in the respiratory system, we can conclude that the waste expelled from the body in the form of gas is carbon dioxide. Therefore, the answer is A. Carbon Dioxide.
