Question

. What are the Uterine changes during initial phase or in the bleeding phase?​

Answer 1

Answer:

The Uterine changes during initial phase or in the bleeding phase are :

Due to withdrawal of sex hormone, prostaglandins are formed in uterus

which cause arteriolar vasoconstriction.

lt leads to decreased blood supply to stratum functionalis that results in its degeneration and separation. Prostaglandin also cause contraction of myometrium which leads to sloughing of dead endometrial functionalis with blood from uterine

cavity through vagina. This bleeding

continues upto 4-5 days and clotting does not occur due to presence of

fibrinolytic enzymes. Average 40 to 80 ml blood loss per cycle.

Answer 2

Answer:

Explanation:

During the secretory phase of the uterus, the hormone progesterone is produced by the ovaries. ... Progesterone also stimulates the glands in the uterus to secrete substances that maintain the endometrium and keep it from breaking down. For this reason, this phase of the menstrual cycle is called the secretory phase.
