The vagina is a muscle tube connected to the cervix, the bottom of the uterus.
The vagina is also called the birth canal and allows blood and cells to flow during menstruation, the introduction of sperm during intercourse and childbirth and placenta at the end of pregnancy.
The vagina has only a limited number of nerve endings, which is important for women to deal with pain at birth.

Fibrous-muscular tube, which is the female genital organ and has two main functions: sexual intercourse and childbirth.
The vagina, the female genital organ, is a fibromuscular tubular duct that has two main functions: intercourse and childbirth.
In humans, this transition leads from the opening of the vulva to the uterus, but the vaginal tract ends at the cervix.

Female mammals usually have two outer holes in the vulva, a urethral opening in the urinary tract and a vaginal opening in the genital tract.
The vaginal opening is much larger than the nearby urethral opening and both are protected by the labia in humans.
In amphibians, birds, reptiles and monotremes, the cloaca is the only external opening for the digestive tract, urinary tract and reproductive organs.
To allow gentler vaginal penetration during sexual intercourse or other sexual activity, vaginal moisture during sexual excitement increases in humans and other sex mammals.
The texture of the vaginal walls causes the penis to rub during sexual intercourse and stimulates it to ejaculate, which enables fertilization.

With age, the vaginal walls become loose and the vagina diameter increases (1).
When it comes to sexual satisfaction, the size of the vagina does not affect sexual function (6).
The perception of vaginal constriction during sexual intercourse is primarily related to the pelvic floor muscles that are around the base of the vagina, and not really how wide the vaginal canal is.
After menopause, the vaginal walls become thinner and more fragile when the estrogen is lower. This can cause symptoms of vaginal dryness and reduced vaginal discharge (5).

When agitated, the vagina becomes moist to facilitate entry into the penis.
The inner texture of the vagina causes friction of the penis during intercourse.
The vaginal opening is at the caudal end of the vulva behind the urethral opening.

The main structures of the vulva include the labia minora, pubic, clitoral, vestibular bulbs, vestibular vestibule, vestibular glands and genital opening (or vaginal opening).
The vulva is rich in nerves that are stimulated during sexual activity and excitement.
The vulva also contains the female urethral opening, and therefore performs the vital function of urination.

The clitoris, a small sensory organ, is located towards the front of the vulva, where the labia connect.
Between the labia are holes for the urethra (the channel that carries piss from the bladder out of the body) and into the vagina.
When the girls become sexually mature, the labia and pubic monsoons are covered with pubic hair.
The vagina is a muscular, hollow tube that extends from the vaginal opening into the uterus.

The clitoral hood is the female counterpart of the male foreskin and can be partially hidden in a bunch gap.
The area between the labia majora is called the vulva vestibule and contains vaginal and urethral holes.
The urethral opening (auditory muscle) is located below the clitoris and directly in front of the vagina.

The vagina is located between the cervix and the external genitalia, especially the vulva.
A series of ridges formed by folding the outer wall of one-third of the vagina is called vaginal rugae.
The hymen is a tissue membrane that surrounds or partially covers the outer vaginal opening.

In mammals, the vagina is a flexible, muscular part of the female genitals.
The outer vaginal opening is usually partially covered by a membrane called the hymen.
At the deep end, the cervix bends in the vagina.

The genitourinary triangle is covered with a membrane of the perineum, a layer of connective tissue that lies between the pubis and is penetrated through the vagina, urethra and the rest of the external genitalia.
The anal triangle consists of the anal canal, the internal and external anal sphincter, the pit of the ischiorectalis and the middle raphe.
The muscles of the external genitalia include the superficial and deep transverse perineum, sciatica that covers the clitoris, and the sciatica.
The blood supply to the external genitalia is mainly from the carotid artery and its branches to the genitourinary triangle and anus.

The vagina is attached laterally to the side walls of the pelvis with the help of connective tissue density and smooth muscles closely related to the adventitious vaginal blood vessels.
In the midline, the relatively vascular bladder-vaginal and rectovaginal spaces allow the vagina to deform freely from both the bladder and rectum.
The rectovaginal septum is anastomosed to the posterior vaginal wall as the front lining of the rectovaginal space.

The vaginal operator can cut directly through the connection point between the bladder and vagina, allowing easy access to the perineum of the anterior bladder.
If this is not immediately apparent, the doctor could make this preparation under the uterine connective tissue capsule well above the anterior peritoneal rebound and peel the peritoneum along with this fibrous fibrous capsule of the uterus from the anterior surface of the uterus.
