Viewing structure in relation to its function holistically we see that the structure of an object defines its function i.e. a table has a flat surface for objects to be placed on it. Just like in biology almost all structures within a cell, molecule or organ play an important role in relation to its function. From the larger sizes, such as tubular organs to smaller in size, for example, microscopic organelles will explore the importance of the structure-function relationship.
There are different types of blood vessels, arteries, veins, and capillaries. Each different blood vessel has a different structure to serve different functions. Here I will be only discussing and comparing the arteries and veins. So each of the main functions is as follows, most arteries carry oxygenated blood away from the heart except umbilical artery and

Enzymes consist of an active site, this active site is unique to the substrate which it binds to. The active site is a tertiary structure which defines what substrate can bind to the active site. The active site is therefore highly specific. The structure and function of enzymes are compared to the lock and key hypothesis, where the lock is the enzyme and the key being the substrate. Another theory which has been presented is the induced fit hypothesis, where the tertiary structure in the active site changes slightly when bonded to the substrate to strengthen the bond between the active site and the substrate. Enzymes display importance of structure, as when certain conditions affect the structure of the active site, the enzyme could denature, disrupting the whole reaction. Key processes such as DNA replication, respiration, and photosynthesis all of which involve enzymes, if the active site structure is not highly specific to the substrate, due to being denatured it affects the whole
