• C. Follicular phase and lasts for about 13 days
• D. Luteal phase and lasts for about 13 days

Answer 1

The correct option is D

Luteal phase and lasts for about 13 days

The correct option is D.

Explanation of the correct option:

1. Between 11 to 17 days is the typical length of the luteal phase.
2. The luteal phase typically lasts 12 to 14 days in most females.
3. If our luteal phase is shorter than 10 days, it is regarded as short.
4. In other words, if our menstruation comes 10 days or less after ovulation, we have a short luteal phase.

Explanation of the incorrect options:
Option A:

1. When We ovulate, it comes to an end. It starts on the first day of our menstruation.
2. The follicular phase lasts, on average, 16 days.
3. However, depending on our cycle, it might last anywhere from 11 to 27 days.
4. Our follicular phase's duration is somewhat influenced by how long it takes for one dominant follicle to emerge.

Option B:

1. It usually takes the luteal phase 12 to 14 days to complete.
2. Our ovaries produce the hormone progesterone at this time.
3. It instructs our uterus' lining to expand.

Option C:

1. An additional hormone is released once the follicle reaches maturity, and this hormone causes the uterus' soft tissue lining to develop.
2. This lining develops after the lining from the preceding cycle has been shed, and it will aid in supporting a fertilized egg for a successful pregnancy.

Final answer:
The secretory phase in the human menstrual cycle is also called the luteal phase and lasts for about 13 days.
