Please explain your question more specified
The structure of the lipid bilayer allows small, uncharged substances such as oxygen and carbon dioxide, and hydrophobic molecules such as lipids, to pass through the cell membrane, down their concentration gradient, by simple diffusion.
Your answer would be D, Systemic circulation carries oxygenated blood to the body and pulmonary circulation carries deoxygenated blood to the lungs.
These two circulations are part of the circulatory system, with the pulmonary circulation taking deoxygenated blood to the lungs and returning it oxygenated with the oxygen we breathe in, then that oxygenated blood going around the body delivering that oxygen and coming back deoxygenated.
Hope this helped!
