3470. FMA. 7209. Anatomical terminology. [ edit on Wikidata] The ovary (from Latin ōvārium 'egg, nut') is a gonad in the female reproductive system that produces ova; [ 1 ] when released, an ovum travels through the fallopian tube / oviduct into the uterus. There is an ovary on the left and the right side of the body.
It begins with a single fertilized egg and culminates 38 weeks later with the birth of a male child. It is a part of the stages of sexual differentiation. The development of the male reproductive system coincides with the urinary system. Their development can also be described together as the development of the urinary and reproductive organs.
External genitalia of an adult female (left) and male (right). The human reproductive system includes the male reproductive system, which functions to produce and deposit sperm, and the female reproductive system, which functions to produce egg cells and to protect and nourish the fetus until birth. Humans have a high level of sexual ...
A sex organ, also known as a reproductive organ, is a part of an organism that is involved in sexual reproduction. Sex organs constitute the primary sex characteristics of an organism. Sex organs are responsible for producing and transporting gametes, as well as facilitating fertilization and supporting the development and birth of offspring.
Human reproduction is sexual reproduction that results in human fertilization to produce a human offspring. It typically involves sexual intercourse between a sexually mature human male and female. [1] During sexual intercourse, the interaction between the male and female reproductive systems results in fertilization of the ovum by the sperm to ...
Human fertilization is the union of an egg and sperm, occurring primarily in the ampulla of the fallopian tube. [ 1 ] The result of this union leads to the production of a fertilized egg called a zygote, initiating embryonic development. Scientists discovered the dynamics of human fertilization in the 19th century.
The ovary is differentiated into a central part, the medulla of ovary, covered by a surface layer, the germinal epithelium. The immature ova originate from cells from the dorsal endoderm of the yolk sac. Once they have reached the gonadal ridge they are called oogonia. Development proceeds and the oogonia become fully surrounded by a layer of ...
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.
