The cell membrane is the outer boundary of animal cells and plant cells, but plant cells also have a cell wall to protect their cells. The cell membrane and cell walls are the outer boundaries of cells.
The wall of the arterioles contain less elastic fibers but more smooth muscle cells than that of the aorta and arteries.

Its structure determines the function it has. For example, red blood cells are biconcave discs, kind of thinner in the middle and thicker around the outside. As it turns out this is the ideal surface area to volume ratio for exchanging things between the inside of the cell and outside. When you consider that the function of red blood cells to carry oxygen to the cells of the body the structure of the RBC is ideally suited to its function.
