Now, Relaxant is not only released by aroplacenta, it is also produced by the corpus luteum as well as other structures and is also produced in males now in females and during pregnancy. What relaxant does is basically serves two important functions. Firstly it increases the flexibility of the joints and ligaments found inside our pelvic region of the women which is similar to what estrogen does. And relaxin also basically makes the pubic synthesis, the bone in this region, very relaxed. And this prepares the mother for labor, for childbirth. And secondly, it also increases the blood rate as well as the rate at which our heart actually pumps blood.
