The main function of the male reproductive system is to produce and deliver sperm.
The main function of the female reproductive system is to produce ova. In addition, the female
reproductive system prepares the female's body to nourish a developing embryo.
The reproductive system ensures continuity that the species by producing offspring. This system, doesn’t “kick in”
until puberty. The primary sex organs are the __________________ in males in the ______________ in females.
MALE - reproductive role of the male is to manufacture male gametes (__________________) and deliver
them to the female reproductive tract. The primary reproductive organs of the male are the ____________
which have both and exocrine (sperm-producing) and an endocrine (testosterone-producing) function. The
___________ is designed to deliver sperm into a female reproductive tract as well as for urination. It is the
outward part of the male reproductive system.
Sperm are derived from Special Cells within the Testes that go through the process of MEIOSIS to form HAPLOID
NUCLEI found in Mature Sperm. The Chromosome number drops from 46 to 23, Four sperm cells result from
each cell that begins meiosis.
PATHWAY:
A Mature Sperm consists of THREE Regions:
A. HEAD B. MID PIECE C.
TAIL –
FEMALE - produces gametes called ova (_____________________), fuses with a sperm (called
_______________) and provide, in the uterus, an environment in which the embryo develops until birth (located
in the pelvis between the urinary bladder and the rectum). The vagina is a thin walled tube, which lies between
the bladder and rectum and is often referred to as the birth canal - provides a passageway for the delivery of an
infant and for the menstrual flow to leave the body. ____________________ are the primary reproductive
organs of a female which produce both exocrine (_________________) and endocrine (_______________ and
________________) products. The other organs serve as accessory structures to transport, nurture, or
otherwise serve the needs of the reproductive cells and/or the developing fetus.
PATHWAY:
The menstrual cycle has four phases:
1. follicular phase
