Solution
The inner glandular wall of the uterus is known as endometrium.
Role - During the menstrual cycle, the endometrium wall grows into a thick, blood vessel-rich, glandular layer. This condition of the endometrium favours the implantation of the foetus. If fertilisation does not occur, the endometrium is shed during the hemorrhagic phase of the menstrual cycle.
The middle wall of the uterus is known as myometrium.
Role- It consists of smooth muscles. It brings about contraction while delivery of the baby.
