The organs of the female reproductive system are concentrated in the pelvic cavity. Many of the female reproductive organs are attached to the broad ligament, a sheet of tissue that supports the organs and connects the sides of the uterus to the walls and floor of the pelvis.
Ovaries
The ovaries are two almond-shaped structures approximately 2 inches (5 centimeters) wide, one on each side of the pelvic cavity.

Taxonomy is the science that seeks to classify and organize living things, expressed as a series of mutually exclusive categories. The highest (most inclusive) category is domain, of which there are three: Archea, Eubacteria, Eukaryota. Each of these domains is split into kingdoms, which are further divided until each individual organism is its own unique species.

Biology is a very special application of the laws of chemistry and physics. Biology follows and never violates the laws of the physical sciences, but this fact can sometimes be obscured in the complexity and other special characteristics of biological chemistry and physics.Following is a review of some of the principles of chemistry and physics that have special application in anatomy and physiology.

A watery environment is a requirement for a great proportion of your body's metabolic reactions (the rest need a lipid, or fatty, environment). The body contains a lot of water: in your blood, in your cells, in the spaces between your cells, in your digestive organs, here, there, and everywhere.Not pure water, though.

The 280 days, usually expressed as 40 weeks, are the human gestational period (length of pregnancy). This period is divided, again by convention, into three trimesters, though nothing specific marks the transition from one to the next.Officially, by convention, Day 1 of a pregnancy is the first day of the woman's previous menstrual period.

One way to think of human development is as the unfolding in real time and space of a program for generating a unique biological organism. The program is launched when a new zygote comes into existence. All zygotes are created the same way and then proceed down the path of development encoded in their own species-specific and individual-specific DNA.

Human birth is a commonplace miracle: from a single infinitesimal cell to a human baby in less than ten months. The following sections give a brief overview of how it happens.
Free-floating zygote
Following is a description of the events leading to the fertilization of a secondary oocyte and implantation of the blastocyst in the uterus from the point of view of the zygote, from the fusion of the haploid genomes of the parent gametes to implantation in the uterus.

Jargon is a set of words and phrases that people who know a lot about a particular subject use to talk together. Anatomists and physiologists use jargon, much of which is shared with medicine and other fields of biology, especially human biology.Scientists try to create terminology that's precise and easy to understand by developing it systematically.

Terms that indicate direction make no sense if you're looking at the body the wrong way. You likely know your right from your left, but ignoring perspective can get you all mixed up. Stand up straight. Look forward. Let your arms hang down at your sides and turn your palms so they're facing forward. You are now in anatomical position.
