What is a Fallopian Tube?
A fallopian tube is a long, thin tube that links the ovary to the uterus. Eggs travel down the fallopian tubes to the uterus, where they can be fertilized by sperm.
Structure of Fallopian Tubes
The fallopian tubes are a pair of tubes that extend from the uterus to the ovaries. The tubes are about 10 cm long and about 1 cm in diameter. The tubes are covered by a thin layer of tissue called the serosa. The tubes are divided into three sections: the infundibulum, the isthmus, and the ampulla.
The infundibulum is the funnel-shaped part of the tube that lies at the ovary. The isthmus is the narrow part of the tube that joins the infundibulum and the ampulla. The ampulla is the enlarged part of the tube that lies near the uterus.
The fallopian tubes are lined with cilia. The cilia help to move the eggs from the ovaries to the uterus. The fallopian tubes also contain muscles that help to move the eggs and the sperm.
Menstrual Cycle
Menstrual cycle is the monthly process of changes that occur in the female reproductive system. It is controlled by hormones and it affects the ovaries, uterus, and vagina. The menstrual cycle begins on the first day of a woman’s period and ends about a week before the next period.
There are four main phases of the menstrual cycle: the follicular phase, ovulation, the luteal phase, and the menstrual phase.
The follicular phase begins on the first day of the period and ends when the follicle ruptures and releases the egg. The ovulatory phase begins when the egg is released and ends when the egg is fertilized or the woman’s period begins. The luteal phase begins when the egg is fertilized or the woman’s period begins and ends when the egg is released. The menstrual phase begins when the woman’s period begins and ends a week before the next period.
The main hormones involved in the menstrual cycle are estrogen and progesterone. Estrogen is responsible for the development of the follicle and the egg. Progesterone is responsible for the thickening of the uterine lining in the luteal phase.
FAQs
What is the menstrual cycle?
The menstrual cycle is the process that the body goes through in order to prepare for a possible pregnancy each month. The cycle is made up of four phases: the menstrual phase, the follicular phase, the ovulatory phase, and the luteal phase.
What is the menstrual phase?
The menstrual phase is the first phase of the menstrual cycle. This is when the body sheds the lining of the uterus. This phase typically lasts for about two to seven days.
What is the follicular phase?
The follicular phase is the second phase of the menstrual cycle. This is when the body starts to produce a follicle, which is a structure that contains an egg. This phase typically lasts for about 10 to 14 days.
What is the ovulatory phase?
The ovulatory phase is the third phase of the menstrual cycle. This is when the egg is released from the follicle. This phase typically lasts for about two days.
What is the luteal phase?
The luteal phase is the fourth and final phase of the menstrual cycle. This is when the body produces the hormone progesterone. This phase typically lasts for about 14 days.
