Verified
The movement of both oxygen and carbon dioxide in the body is accomplished by ____.
A) exocytosis and endocytosis
B) bulk flow
C) osmosis
D) diffusion
E) facilitated diffusion
Diffusion
The passive movement of molecules or particles from an area of higher concentration to an area of lower concentration, a process fundamental to many biological systems.
Bulk Flow
The movement of fluid and its constituents in one direction, driven by pressure, gravity, or another external force, commonly observed in bodily functions and ecosystems.
Exocytosis
The process by which cells release substances to the extracellular environment by fusing vesicles with the plasma membrane.
- Illuminate the chemical pathways involved in gas exchange, particularly the roles played by enzymes and the concept of concentration gradient.
- Understand the process of aerobic respiration and the transport of gases in the body.

Final Answer :
D
Explanation :
The movement of oxygen and carbon dioxide in the body is accomplished by diffusion, which is the movement of molecules from an area of high concentration to an area of low concentration. This process does not involve exocytosis, endocytosis, bulk flow, osmosis, or facilitated diffusion.
