Passive transport plays a crucial role in oxygen's journey through our body. Oxygen is a small molecule that can passively diffuse across cell membranes, allowing it to move from areas of higher concentration to areas of lower concentration without the need for energy input. This passive diffusion of oxygen helps it move from the lungs into the bloodstream, and then into the cells where it is needed for cellular respiration. By utilizing passive transport, oxygen can efficiently and effectively navigate through our body and reach the tissues and organs that require it to function properly.

Answer 1

Passive transport is important for oxygen's travels in our body. Oxygen is a small molecule that can move through cell membranes without any energy needed. This allows oxygen to move from areas with a lot of oxygen to areas with less, like from the lungs into the blood and then into cells for respiration. Passive transport helps oxygen get where it needs to go efficiently and effectively in our body.
