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.

<span><span>The correct answer is </span>b. LH.</span>
Luteinizing hormone (LH) is a pituitary hormone with the influence on both, male and female reproductive system, regulated by gonadotropin-releasing hormone (GnRH). In males, LH acts upon the interstitial cells (or Leydig cells) of the testis, which produce testosterone. LH regulates the expression of the enzyme that is used to convert the precursor of the testosterone to testosterone.
