How many parts are there in respiration?

One
Two
Three
Four

The correct answer is: Two

Respiration involves two primary stages: external respiration and internal respiration. External respiration is the process by which oxygen is exchanged for carbon dioxide in the lungs, allowing the body to take in oxygen needed for cellular processes. Internal respiration, on the other hand, occurs at the cellular level, where oxygen is utilized for the production of energy and carbon dioxide is generated as a waste product. These two processes work together to sustain life by ensuring that oxygen is available to cells for metabolism and that carbon dioxide, a byproduct of that metabolism, is effectively removed from the body. Understanding these two components is essential for anyone studying the respiratory system and its functions in maintaining homeostasis in the body.
