Chapter 18 - Female Reproductive System

The femal reproductive system includes ovaries, oviduct, uterus, vagina and placenta during pregnancy and mammary glands for post-natal nutrition.


The Ovaries produces ovum that when released travel down the oviducts into the uterus.

The oviducts (uterine ducts, Fallopian tubes) are fibromuscular tubes that transport the ovulated oocytes from the ovary to the uterus.

The uterus is a muscular organ that is connected to the oviducts. It is within the uterus that the fetus develops during gestation.

Uterus - Menstrual Cycle

During the menstrual cycle, the inner surface of the uterus (endometrium) grows into a thick, blood vessel-rich tissue lining that allows implantation of an embryo upon its arrival in the uterus. In the absence of implantation, the cells die off, shed and pass out as menstrual bleeding.

The cervix is the lower end of the uterus and opens into the vagina.

MHS 207 Cervis

MH 172 Cervis


The vagina is a fibromuscular tube that connects the uterus to the opening of the external genitalia.

MH 173 Vagina

Mammary Gland

After the birth of a baby, the mammary glands synthesize and secrete milk components for its nutriution.

MHS 218 Mammary Gland



The placenta develops during pregnancy to support the developing fetus by producing hormones and transferring nutrients and waste products between the mother and the fetus.
