Most cells use active transport proteins embedded in the membrane to allow large or polarized molecules to pass through rather than simply dissolve through like most ions and water molecules can.

Small cells have a higher surface area to volume ratio, which allows for a more efficient exchange of substances with their environment. This is because the surface area of a cell determines the rate at which substances can be exchanged, and smaller cells have a greater surface area relative to their volume compared to larger cells.
Exocytosis takes substances out of the cell and endocytosis brings substances into the cell.

There are only two substances found in between the blood cells and the capillaries. These are plasma and interstitial fluid.
Phagocytosis is the process where cells engulf and ingest other cells or solid particles. Endocytosis is a general term for the process by which cells take in substances from outside the cell by engulfing them in a vesicle.
DNA stores the genetic information that cells use to make the substances they need through a process called protein synthesis. This information is carried in the form of genes and is used to create specific proteins that perform various functions in the cell.
