The cell membrane (a ring around the cell that provides protection and in the animal cell's case, shape) controls the movement of materials in and out of the cell, but in the plant cell's case, the cell wall ,which is thicker than the cell membrane and outside of it, does more of the work. It also has canals that allow fluids to move through the plant.

Cell walls are semi-permeable, and material is transferred through them by apoplastic transport.
Nutrients are exchanged between the blood and body cell in the capillaries.
There are many substances they exchange, but the main ones are oxygen from the blood to the cells and CO2 from the cells to the blood.
Capillary: A tiny blood vessel where substances are exchanged between the blood and the body cells.
Anchoring junctions link intermediate filaments to adjacent animal cells, attaching the cells but still allowing movement or stretching.
interconnects the plant cells and gap junctios for animal cells

Adjacent cells are cells that are together, and do not have other cells between each other. A cell beside another one are together called adjacent cells, as are cells that are above or below each other and touching. So A1 and A2 are adjacent cells, as are B1 and C1. A1 and C1 are not adjacent cells as B1 is between them. A1, B1 and C1 would be adjacent cells.

Junctions in Animal Cells A tight junction is a watertight seal between two adjacent animal cells. The cells are held tightly against each other by proteins, preventing materials from leaking between the cells.

Materials are spread to different places of your body, but it depends on what material it is that determines where, but some materials stay in the blood just like you need oil in a tank.
Those tiny and beautiful blood vessels are called as capillaries. You have millions of them in your body. The nutrition and oxygen is given out, at the proximal end. The metabolic wastes and carbon bi oxide in taken in, at the distal end.
