During this phase, the following events occur: The luteal phase of the menstrual cycle begins right after ovulation and involves the following processes: The vast majority of the eggs within the ovaries steadily die, until they are depleted at menopause. These are accessory reproductive organs of the female reproductive system. A collection of ligaments hold the ovaries in position and attach them to the uterus. The vagina is surrounded by three layers, the outer layer of areolar tissue, a middle layer of smooth muscle, and the inner layer of stratified squamous epithelium that forms ridges or rugae. They have no reproductive significance. Unlike the male reproductive organs, the female reproductive organs are located mostly in the pelvic cavity. Fallopian tubes are divided into four sections: Fimbriae: Finger-like projections, entry point of the ovum into the fallopian tube when it is ejected from the ovary. The reproductive systems primary goal is to keep a species alive. In such a case, it is released into the peritoneal cavity. To find out more, read our privacy policy.

Fertilization normally happens in the fallopian tubes. Hall JE and Guyton AC. After fertilization, the secretions of the tubes provide nutrients to the zygote. As a result, they stop growing and die. These phases include: There are four major hormones (chemicals that stimulate or regulate the activity of cells or organs) involved in the menstrual cycle. The external genitalia includes the mons pubis, labia majora, labia minora, clitoris, and structures associated with the vestibule. The intramural (interstitial) part that transverses the myometrium of the uterus. The function of your external genitals are to protect the internal parts from infection and allow sperm to enter your vagina. The menstrual cycle is a series of natural changes in hormone production and the structures of the uterus and ovaries of the female reproductive system that make pregnancy possible.

The femoral artery is one of the major arteries in the human body. Ovaries are the primary reproductive organs of the female reproductive system as they directly take part in reproduction. Ninth Edition. As the follicular phase progresses, one follicle in one ovary becomes dominant and continues to mature. The blastocyst reaches the uterus and gets attached to the endometrium of the uterus by about 7th day after the fertilization process. Made with by Sagar Aryal.

The ovaries are attached to the upper part of the uterus by the ovarian ligament called mesovarium and are connected to the fallopian tubes by a deep tissue called an infundibulopelvic ligament. This process is called parturition. The follicular Egg-producing physiology. Females are born with a large number of potential ova (female sex cells, also called egg cells). If the egg is not fertilized, it passes through the uterus. This causes the dominant follicle to release its egg from the ovary. In an adult female, the uterus weighs about 30-40 grams and is approximately 7.5cm long, 5cm wide with 2.5cm thick walls. The female reproductive anatomy includes parts inside and outside the body.

The hypothalamic releasing hormone, gonadotropic hormone (GnRH): This hormone stimulates the anterior pituitary to release sex hormones, Follicle Stimulating Hormone (FSH) and Luteinizing Hormone (LH). In addition, the female reproductive system produces female sex hormones that maintain the reproductive cycle. The internal genitalia is present in the pelvic cavity of a female and consists of a uterus, a vagina, two uterine tubes, and two ovaries. Once it releases its egg, the empty follicle develops into a new structure called the corpus luteum. Therefore, there is weakening of the follicular wall. A Zygote is a cell that is produced during fertilization. The primary purpose of uterine tubes is to facilitate the transport of ovum from the ovary to the uterus.

Fertility also declines with age due to the decreasing number and quality of your remaining eggs. Fertilisation the final stage of female gametogenesis It provides both space and nourishment to the developing baby. Uterine secretions provide nourishment to the ovum before its implantation on the wall and, later after fertilization, the rapidly expanding ball of cells is nourished by the endometrial cells. The fallopian tubes are located in the pelvis and function to transport eggs from the ovaries to the uterus. Usually, the walls of the vagina are moist and have a pH ranging from 3.8 to 4.2. Hymen: In most women, the mucosa near the distal vaginal orifice forms an incomplete partition called the hymen.
