The reproductive system review
The female reproductive system functions to produce gametes and reproductive hormones, just like the male reproductive system; however, it also has the additional task of supporting the developing fetus and delivering it to the outside world. Unlike its male counterpart, the female reproductive system is located primarily inside the pelvic cavity Figure Recall that the ovaries are the female gonads. The gamete they produce is called an oocyte. The external female reproductive structures are referred to collectively as the vulva Figure
Human reproductive system , organ system by which humans reproduce and bear live offspring. Provided all organs are present, normally constructed, and functioning properly, the essential features of human reproduction are 1 liberation of an ovum , or egg , at a specific time in the reproductive cycle, 2 internal fertilization of the ovum by spermatozoa, or sperm cells, 3 transport of the fertilized ovum to the uterus , or womb, 4 implantation of the blastocyst, the early embryo developed from the fertilized ovum, in the wall of the uterus, 5 formation of a placenta and maintenance of the unborn child during the entire period of gestation , 6 birth of the child and expulsion of the placenta, and 7 suckling and care of the child, with an eventual return of the maternal organs to virtually their original state. For this biological process to be carried out, certain organs and structures are required in both the male and the female. The source of the ova the female germ cells is the female ovary ; that of spermatozoa the male germ cells is the testis. In females, the two ovaries are situated in the pelvic cavity; in males, the two testes are enveloped in a sac of skin, the scrotum , lying below and outside the abdomen. Besides producing the germ cells, or gametes , the ovaries and testes are the source of hormones that cause full development of secondary sexual characteristics and also the proper functioning of the reproductive tracts.
Everything to Know About Female Reproductive Organs
The uterus is a secondary sex organ. Secondary sex organs are components of the reproductive tract that mature during puberty under the influence of sex hormones produced from primary sex organs the ovaries in females and the testes in males. The uterus is a thick-walled muscular organ capable of expansion to accommodate a growing fetus. It is connected distally to the vagina, and laterally to the uterine tubes. The exact anatomical location of the uterus varies with the degree of distension of the bladder. In the normal adult uterus, it can be described as anteverted with respect to the vagina, and anteflexed with respect to the cervix:.
The human female reproductive system contains two main parts: the uterus and the ovaries, which produce a Describe the structure and function of the uterus.
The Fallopian (Uterine) Tubes
These parts are internal; the vagina meets the external organs at the vulva, which includes the labia, clitoris, and urethra. The vagina is attached to the uterus through the cervix, while the uterus is attached to the ovaries via the fallopian tubes. At certain intervals, the ovaries release an ovum, which passes through the fallopian tube into the uterus. If, in this transit, it meets with sperm, the sperm penetrates and merges with the egg, fertilizing it. The fertilization usually occurs in the oviducts, but can happen in the uterus itself.
The female reproductive system consists of both internal and external parts. It has several important functions, including:. But what are the individual parts of the female reproductive system, and what do they do?
Female reproductive system
Ovaries are the female gonads — the primary female reproductive organs. These glands have three important functions: they secrete hormones, they protect the eggs a female is born with and they release eggs for possible fertilization. Human females are typically born with two ovaries stemming from the uterus. Before puberty, ovaries are just long bundles of tissue. As the female matures, so do her ovaries. When mature, ovaries are about the size of a large grape , according to EndocrineWeb. The ovaries lie on either side of the uterus against the pelvic wall in a region called the ovarian fossa.
This article will look at the function, parts, vasculature and innervation of the fallopian tubes, as well as any clinical relevance. The main function of the uterine tubes is to assist in the transfer and transport of the ovum from the ovary, to the uterus.

The female reproductive system is made up of the internal and external sex organs that function in reproduction of new offspring. In humans, the female reproductive system is immature at birth and develops to maturity at puberty to be able to produce gametes , and to carry a foetus to full term. The internal sex organs are the uterus , Fallopian tubes , and ovaries. The uterus or womb accommodates the embryo which develops into the foetus. The uterus also produces vaginal and uterine secretions which help the transit of sperm to the Fallopian tubes.

Послание ничем не отличалось от многих других, которые он получал: правительственное учреждение просит его поработать переводчиком в течение нескольких часов сегодня утром. Странным показалось только одно: об этой организации Беккер никогда прежде не слышал. Беккер позвонил одному из своих коллег: - Тебе что-нибудь известно об Агентстве национальной безопасности.
