If the blood vessels are replaced with collagen connective tissue, they will no longer be elastic and become hard, so the vessels will lose their ability to stretch. This hampers performance.
What is the difference between connective tissue, collagen fibers, and elastic fibers?
- Collagen fibers are the strongest and most abundant of all connective tissue fibers. These are fibrous proteins and are secreted into the extracellular space and they provide high tensile strength to the matrix.
- Elastic fibers are long and thin fibers that form a branching network in the extracellular matrix. They help the connective tissue to stretch and recoil.

A site where pathogens can survive , multiply and serve as a continual source of infection is called the reservoir. It is site where the infectious agent survives.
Reservoir is a host which allows the pathogen to live, and possibly grow and multiply. Humans , animals and environment can be reservior for microorganisms. Principal habitat that which pathogen lives , flourishes and able to multiply.
There are some examples such as humans are the reservior for the measles virus because it does not infect the other organisms. The place where microorganism, resides, thrives and reproduces. A carrier is a person with in-apparent infection who are capable of transmitting the pathogen to others.
