Introduction - Female Reproductive System

• The Human Female Reproductive System is a complex system designed to perform several important functions such as production of ovum, providing the site for fertilization, implantation and development of the fetus, and giving birth.
• Unlike the male reproductive system, most parts of the female system are located inside the pelvic cavity or Pelvis region which makes understanding its anatomy with a labelled diagram very important for NEET. The female reproductive system is divided into two parts:
• Primary Sex Organ - Ovary: It produces the ovum (female gamete) and secretes female sex hormones - Estrogen and Progesterone.
• Accessory Sex Organs:These include the Fallopian tubes (Oviducts), Uterus, Vagina, External Genitalia (Vulva) and Mammary Glands. They help in transport of gametes, fertilization and child care.
• For NEET , the most important topics from this system are the 3 layers of the Uterus (Perimetrium, Myometrium, Endometrium) and the 4 parts of the Fallopian Tube. Direct diagram-based questions are asked from these topics every year.
• In this post, we will study the structure of each organ of the Female Reproductive System one by one with a clear labelled diagram. We have not included Menstrual Cycle and Oogenesis in this post to keep your concepts clear and focused.

Human female reproductive system diagram labelled for NEET

Main Parts of Female Reproductive System

• The female reproductive system consists of following parts:

1. Ovary - Location, Structure, Function

• There are two ovaries, one on each side of the lower abdomen. Each ovary is about 2-4 cm in length. Ovaries are connected to the pelvic wall and uterus by ligaments.
• Ovary is covered by a thin epithelium which encloses the ovarian stroma. The stroma is divided into two zones - outer cortex and inner medulla.

Function:

• It Produces female gamete  in form of Ovum.
• It acts as an endocrine gland and secretes hormones  Estrogen and Progesterone.

2. Oviduct / Fallopian Tube 

• Fallopian tubes are about 10-12 cm long. Each tube is divided into 3 parts. This is a very important topic for NEET.
• Infundibulum  is the funnel-shaped opening near the ovary. Its edges have finger-like projections called Fimbriae, which help in collection of the ovum after ovulation.
• Ampulla is the widest and longest part of the fallopian tube. Fertilization takes place in the Ampulla.This is a direct NEET question. 
• Isthmus is a narrow portion with a thick wall. It connects the Ampulla to the Uterus.

Part of Fallopian Tube	Feature	Function (NEET Point)
Infundibulum	Funnel-shaped with Fimbriae	Collects ovum after ovulation
Ampulla	Widest part	Site of Fertilization
Isthmus	Narrow, connects to uterus	Transport of zygote to uterus

3. Uterus (Womb) and  three Layers : 

• Uterus is a single, inverted pear-shaped, hollow muscular organ located in the pelvic cavity. It is the site for implantation and fetal development. The three layers of uterus are as 
• Perimetrium is Outer thin membranous layer. It is the outer protective serous layer.
• Myometrium is Middle thick layer made of smooth muscles. It shows strong contractions during delivery of the baby. This is the thickest layer.
• Endometrium is Inner glandular layer that lines the uterine cavity. It undergoes cyclic changes during menstrual cycle and is necessary for implantation.

4.Cervix and Vagina 

• Cervix is the lower narrow part which opens into the Vagina. Cervix has a canal called Cervical Canal.  It is the lowermost part of the uterus. It contains Cervical Canal which along with Vagina forms the Birth Canal.
• Vagina is a muscular tube of about 7-9 cm length. It has two main functions: It receives the sperm during copulation. It acts as a Birth Canal during parturition (childbirth).

External Genitalia (Vulva) - Short Note

• The external genitalia of female is collectively called Vulva. It includes the following parts:
• Mons Pubis is a cushion of fatty tissue covered by skin and pubic hair.
• Labia Majora  are two large fleshy folds of tissue which surround the vulva. They are homologous to the scrotum in males.
• Labia Minora are two smaller fleshy folds which lie inside the Labia Majora.
• Clitoris  is a small finger-like erectile structure present at the upper junction of Labia Minora. It is homologous to the penis in males.
• The vaginal opening is often partially covered by a membrane called Hymen. 
• The Hymen is often torn during the first coitus, but it can also be broken by physical activities like cycling, horse riding etc. So, presence or absence of hymen is not a reliable indicator of virginity.

Structure of Vulva	Feature / Location	NEET Trick & Function
1. Mons Pubis	Fatty cushion covered by skin and pubic hair, above vulva.	Protection, cushion during copulation
2. Labia Majora	Two large outer folds, fleshy, with sweat & sebaceous glands.	Homologous to Scrotum in males
3. Labia Minora	Two small inner folds, more vascular, no hair.	Protects vaginal & urethral opening
4. Clitoris	Tiny finger-like erectile structure at upper junction of labia minora.	Homologous to Penis in male, highly sensitive
5. Hymen	Thin membrane partially covering vaginal opening.	Not a reliable indicator of virginity - NCERT line
6. Bartholin's Gland	Pea-sized gland, one on each side of vaginal orifice.	Lubrication; Homologous to Cowper's Gland

Accessory Glands - Bartholin's Gland & Mammary Glands

• Bartholin's Gland  are two in number and located on each side of the vaginal opening or located in the posterior region of Labia Majora.
• They secrete mucus to provide lubrication during copulation.Their secretion helps to keep the vulva moist. Bartholin's gland in female is homologous to the Bulbourethral Gland (Cowper's Gland) in males. Bartholin's glands are also called Greater Vestibular Glands .

Mammary Glands (Breasts)

• Mammary glands are a characteristic feature of all female mammals. They are paired structures (breasts) that contain glandular tissue and variable amount of fat. 
• The mammary glands are situated over the pectoral muscles on the chest. 
• Each breast contains 15-20 mammary lobes. Each lobe is divided into many lobules containing milk-secreting cells called Alveoli.
• The alveoli open into mammary tubules. The tubules of each lobe join to form a mammary duct. Several mammary ducts join to form a wider Mammary Ampulla, which is connected to Lactiferous Duct through which milk is sucked out.

💡Trick to learn the path by which milk is released in mammary glands :

Aunty : Alveoli 
Toffee  : Tubule 
Do : Duct 
Aur : Ampulla 
Ladoo : Lactiferous 
Do : Duct

External Structure of Breast:

• Nipple is Central conical projection through which milk is released. 
• Areola is Pigmented circular area around the nipple. It contains small sebaceous glands called Areolar glands.

Function of Mammary gland 

• After childbirth, under the effect of hormone Prolactin, milk is produced in alveoli.
• Hormone Oxytocin helps in the ejection of milk during suckling by the baby.
