Some of these parts, called organelles, are specialized structures that perform certain tasks within the cell.
What are capillaries and what is their function?
Capillaries, the smallest and most numerous of the blood vessels, form the connection between the vessels that carry blood away from the heart (arteries) and the vessels that return blood to the heart (veins). The primary function of capillaries is the exchange of materials between the blood and tissue cells.

How does the shape of cells help in their specialized function?
Intestinal lining – Cells located within the intestine are covered with many cilia. This increases their surface area so that more nutrients can be absorbed from the food that is passing. Hopefully, these examples illustrate how the shapes of cells allow them to function within their specialized roles in an organism.
