Subject : Biology

Question:

The longest phase of the menstrual cycle is:

A) Menstruation

B) Ovulation

C) Proliferation

D) Luteal

Expert Verified Solution:

The correct answer is D) Luteal. The menstrual cycle consists of several phases, each with distinct characteristics. The luteal phase is the longest phase, occurring after ovulation and lasting about 14 days in a typical cycle. During this phase, the body prepares for a possible pregnancy. If fertilization does not occur, the luteal phase ends with the start of menstruation, marking the beginning of a new cycle. This phase is characterized by the production of progesterone, which helps maintain the uterine lining for potential implantation.
