Below we will introduce the various parts of the female reproductive system and their functions in detail.
ovary
Ovary is one of the most important organs in female reproductive system. Its main function is to lay eggs and secrete estrogen. The ovary is located on both sides of the pelvic cavity, which is similar to almond in shape and about 3-5 cm in size. There are many follicles in each ovary, only one of which will mature into an egg, and the rest will degenerate and absorb. Every month, a mature egg is released from a woman's ovary. This process is called ovulation.
oviduct
The fallopian tube is the conduit connecting the ovary and uterus. Its main function is to transport eggs from ovary to uterus, which is also the place where eggs are fertilized. The length of fallopian tube is about 10- 12 cm, which is divided into three parts: bladder end, abdominal end and uterus end. After the egg is released from the ovary, it will enter the fallopian tube and finally reach the uterus through the peristalsis of the fallopian tube.
womb
The uterus is the largest organ in the female reproductive system, and its main function is to give birth to the fetus. The uterus is inverted pear-shaped and located in the center of the pelvic cavity, with a size of about 7-8 cm. The inner wall of uterus is rich in blood vessels and glands, which can provide nutrition and oxygen for embryos. When the egg is fertilized, the embryo will enter the uterus, pass through the implantation on the inner wall of the uterus, and finally form the placenta, and the fetus will be born.
vagina
Vagina is the last part of the female reproductive system, which connects the uterus with the outside world and is the channel for sexual intercourse and childbirth. The length of vagina is about 8- 10 cm, and there are many wrinkles on the inner wall, which can be expanded to adapt to delivery. There are many secretions in the vagina, including vaginal secretions and cervical mucus, which can lubricate the vagina and protect the reproductive organs.
operation sequence/order
The schematic diagram of female reproductive system model can be used in medical education and reproductive health education. When using this model, you need to pay attention to the following points:
1. Keep clean: The female reproductive system is a very sensitive organ, which needs to be disinfected and cleaned before use to avoid infection.
2. Soft operation: When operating the model, you need to handle the organ lightly to avoid damage.
3. Understand the function of organs: Before using the model, it is necessary to understand the function and position of each organ to avoid operational errors.
4. Pay attention to hygiene: after using the model, it needs to be cleaned and disinfected to avoid cross infection.
final result
The female reproductive system is a very important system in the human body, which can produce eggs, conceive fetuses and maintain women's health. Understanding the structure and function of female reproductive system is of great significance for protecting female health and reproductive health. The schematic diagram of the female reproductive system model can help people better understand the female reproductive system, improve reproductive health awareness, and prevent and treat reproductive health problems.
