Male and female urinary bladders in lateral cross-section. In humans, the bladder is a hollow muscular organ situated at the base of the pelvis. In gross anatomy, the bladder can be divided into a broad fundus (base), a body, an apex, and a neck. [5]
The uterus or womb is the major female reproductive organ. The uterus provides mechanical protection, nutritional support, and waste removal for the developing embryo (weeks 1 to 8) and fetus (from week 9 until the delivery). In addition, contractions in the muscular wall of the uterus are important in pushing out the fetus at the time of birth.
The lesser pelvis contains the pelvic colon, rectum, bladder, and some of the sex organs. The rectum is at the back, in the curve of the sacrum and coccyx; the bladder is in front, behind the pubic symphysis. In females, the uterus and vagina occupy the interval between these viscera. [1]
Tail end of human embryo, from eight and a half to nine weeks old. 1 - 7: Homologous male and female pelvic organs. Diagrams that show the development of male and female organs from a common precursor.
In human female anatomy, the vesicouterine pouch, also uterovesicle pouch, is a fold of peritoneum over the uterus and the bladder. Like the rectouterine pouch, it is a female pelvic recess, but shallower and closer to the anterior fornix of the vagina.
In women, the rectouterine pouch is the deepest point of the peritoneal cavity. It is posterior to the uterus, and anterior to the rectum. [2] Its anterior boundary is formed by the posterior fornix of the vagina. [1] The pouch on the other side of the uterus near to the anterior fornix is the vesicouterine pouch.
The reverse is true for the Müllerian duct, as it essentially disappears in the male reproductive system and forms the fallopian tubes, uterus, and vagina in the female system. In both sexes, the gonads go on to form the testes and ovaries; because they are derived from the same undeveloped structure, they are considered homologous organs.
The primary reproductive function of the human uterus is to prepare for the implantation of a zygote, a fertilized ovum, and maintenance of pregnancy if implantation occurs. [22] Traveling along the fallopian tube on its way to the uterine cavity, the zygote divides mitotically to become a blastocyst , which ultimately attaches to the uterine ...
