Roles of collagen in the human body

 

Collagen is to the tissues in the human body, what steel rods are to reinforced concrete.

 

If the steel rods of the frame are weak, all the structure weakens. More than twenty kinds of collagen are found in the tissues of the body. Depending on the different types of collagen contained in our body, we will find a variation in the sequences of amino acids.

 

Let us examine collagens types I to V, which represent 99% of all the collagen found in our body. They are present in our body as follows:

 

Type I : Bones, tendons, ligaments and skin;

Type II : Cartilages and structure of the eyes;

Type III : Liver, lungs and arteries;

Type IV : Kidneys and several internal organs;

Type V : Surface of cells, hair and placenta.


Collagen is produced by specialized cells called fibroblasts and is gathered in the conjunctive tissues. The biological role of collagen has a double function. On the one hand, together with elastin and glycoproteins, it is responsible for the cohesion of tissues and organs. On the other hand, collagen gives these tissues and organs hydration, resistance, elasticity and flexibility properties.

 

With respect to conjunctive tissues, they form a weft rich in collagen, which is found practically in every part of our body. They mainly serve as support, filler, joint, insulation, protection or transport in the case of the blood system.

 

Without this conjunctive tissue matrix rich in collagen that acts as "a sort of glue that keeps our body together", we would be a puddle.

The connective tissues are the glue that holds the body together; without these tissues, our body would be like a puddle.
