Menstrual Cycle Explained

Показать описание
The menstrual cycle is a process that occurs every 28 days (on average) in females who have reached puberty. In this video, I discuss the following aspects of the menstrual cycle: plasma hormone levels, changes in the ovary, and changes in the endometrium.

00:00 - Hormones in the menstrual cycle
01:35 - Day 1 to 5 of the menstrual cycle
03:32 - Day 6 to 14 of the menstrual cycle
06:40 - Day 14 to 21 of the menstrual cycle
08:09 - Day 22 to 28 of the menstrual cycle

Catering for IGCSE and SPM students.
